2003 Iraq War Casualties: Death toll

While estimates on the number of casualties during the invasion in Iraq vary widely, the majority of deaths and injuries have occurred after U.S. President Bush declared the end of "major combat operations" on May 1, 2003. According to CNN, the U.S. government reported that 139 American military personnel were killed before May 1, 2003, while over 4,000 have been killed since 2003. Estimates on civilian casualties are more variable than those for military personnel. According to Iraq Body Count, a group that relies on press reports, NGO-based reports and official figures to measure civilian casualties, approximately 7,500 civilians were killed during the invasion phase, while more than 60,000 civilians have been killed as of April 2007.

In November 2006 Iraq's Health Minister Ali al-Shemari said that since the March 2003 invasion between 100,000 and 150,000 Iraqis have been killed. Al-Shemari based his figure on an estimate of 100 bodies per day brought to morgues and hospitals – such a calculation would come out closer to 130,000 in total.

The Lancet surveys of casualties of the Iraq War, conducted by researchers at Johns Hopkins University, estimates much higher civilian casualties, but does not differentiate between the invasion phase (March–May 2003) and the occupation phase (post May 2003). The Lancet survey estimates that over 650,000 Iraqis have died as a result of the conflict, with the vast majority of these deaths occurring after May 2003. These studies were highly controversial at their time of publication, attracting considerable criticism.

On January 9, 2008, the World Health Organization reported the results of the Iraq Family Health Survey published in The New England Journal of Medicine. The study surveyed 9,345 households across Iraq and estimated 151,000 deaths due to violence (95% uncertainty range, 104,000 to 223,000) from March 2003 through June 2006. Employees of the Iraqi Health Ministry carried out the survey.

A September 14, 2007 estimate by ORB (Opinion Research Business), an independent British polling agency, suggests that the total Iraqi violent death toll due to the Iraq War since the US-led invasion is more than 1.2 million (1,220,580). Although higher than the 2006 Lancet estimate, these results, which were based on a survey of 1499 adults in Iraq from August 12–19, 2007, are reasonably consistent with the figures that were published in the Lancet study.

On January 28, 2008, ORB published an update based on additional work carried out in rural areas of Iraq. Some 600 additional interviews were undertaken and as a result of this the death estimate was revised to 1,033,000 with a given range of 946,000 to 1,120,000.

Iraqi refugees

Over 4.2 million Iraqis, more than 16% of the Iraqi population, have lost their homes and become refugees since 2003. As of June 21, 2007, the United Nations High Commissioner for Refugees estimated that 2.2 million Iraqis had been displaced to neighboring countries, and 2 million were displaced internally, with nearly 100,000 Iraqis fleeing to Syria and Jordan each month. Roughly 40% of Iraq's middle class is believed to have fled, the U.N. said. Most are fleeing systematic persecution and have no desire to return. All kinds of people, from university professors to bakers, have been targeted by militias, insurgents and criminals. Approximately 331 school teachers were slain in the first four months of 2006, according to Human Rights Watch, and at least 2,000 Iraqi doctors have been killed and 250 kidnapped since the 2003 U.S. invasion.

The UN reports that although Christians comprise less than 5% of Iraq's population, they make up nearly 40% of the refugees fleeing Iraq. More than 50% of Iraqi Christians have already left the country. In 1987, the last Iraqi census counted 1.4 million Christians. But as the war has radicalized Islamic sensibilities, Christians' total numbers slumped to about 500,000, of whom 250,000 live in Baghdad. Furthermore, the Mandaean and Yazidi communities are at the risk of elimination due to ethnic cleansing by Islamic extremists. As many as 110,000 Iraqis could be targeted as collaborators because of their work for coalition forces.

A May 25, 2007 article noted that in the previous seven months, only 69 people from Iraq had been granted refugee status in the United States.

War Crimes in 2003 Iraq War

After the ambush of the 507th Maintenance Company during the battle of Nasiriyah on March 23, the bodies of several American soldiers who had been killed in the ambush were shown on Iraqi television. Some of these soldiers had visible gunshot wounds to head, leading to speculation that they had been executed. Except for Sgt. Donald Walters, no evidence has since surfaced to support this scenario and it is generally accepted that the soldiers were killed in action. Five live prisoners of war were also interviewed on the air, a violation of the Geneva Conventions.

Sergeant Donald Walters was initially reported to have been killed in the March 23 ambush of the 507th Maintenance Company after killing several Fedayeen before running out of ammunition. However, an eyewitness later reported that he had seen Walters being guarded by several Fedayeen in front of a building. Forensics work later found Walters' blood in front of the building and blood spatter suggesting he died from two gunshot wounds to the back at close range. This led the Army to conclude that Walters had been executed after being captured, and he was posthumously awarded the Prisoner of War Medal in 2004.

It was alleged in the authorized biography of Pfc. Jessica Lynch that she was raped by her captors after her capture as part of the 507th Maintenance Company, based on medical reports and the pattern of her injuries, though this is not supported by Ms Lynch. Mohammed Odeh al-Rehaief, who later helped American forces rescue Lynch, stated that he saw an Iraqi Colonel slap Lynch while she was in her hospital bed. The staff at the hospital where Lynch was held later denied both stories, saying that Lynch was well cared for. While Lynch suffers from amnesia due to her injuries, Lynch herself has denied any mistreatment whilst in captivity.

Also on March 23, a British Army engineering unit made a wrong turn near the town of Az Zubayr, which was still held by Iraqi forces. The unit was ambushed and Sapper Luke Allsopp and Staff Sergeant Simon Cullingworth became separated from the rest. Both were captured and executed by Iraqi irregular forces. In 2006, a video of Allsopp lying on the ground surrounded by Iraqi irregular forces was discovered.

Marine Sergeant Fernando Padilla-Ramirez was reported missing from his supply unit after an ambush north of Nasiriyah on March 28. His body was later dragged through the streets of Ash-Shatrah and hung in the town square. His body was later taken down and buried by sympathetic locals. His body was discovered by American forces on April 10.

During the Battle of Nasiriyah, there was an incident where Iraqi irregulars feigned surrender to approach an American Marine unit securing a bridge. After getting close to the Marines, the Iraqis suddenly opened fire, killing 10 Marines and wounding 40. In response, American forces reinforced security procedures for dealing with prisoners of war.

On March 30, soldiers from the British Royal Scots Dragoon Guards reported that they had observed Fedayeen fighters using children as human shields in the village of Kuj Al Mum. On March 31, Iraqi Republican Guard units were reported to be using women as human shields outside of Hindiyah. Many other incidents of Fedayeen fighters using human shields were reported from various towns in Iraq.

Some reports indicate that the Fedayeen used ambulances to deliver messages and transport fighters into combat. On March 31, Fedayeen forces in a Red Crescent marked ambulance attacked American soldiers outside of Nasiriyah, wounding 3.

During the Battle of Basra, British forces of the Black Watch (Royal Highland Regiment) reported that on March 28, Fedayeen forces opened fire on thousands of civilian refugees fleeing the city, wounding several people.

Fedayeen and Republican Guard forces were reported to have executed Iraqi soldiers who tried to surrender on multiple occasions, as well as threatening the families of those who refused to fight. One such incident was directly observed during the Battle of Debecka Pass.

Members of the Coalition included Australia: 2,000 invasion, Poland: 200 invasion—2,500 peak, United Kingdom: 46,000 invasion, United States: 150,000 to 250,000 invasion

United Kingdom

British troops, in what was codenamed Operation (or Op) TELIC participated in the 2003 Invasion of Iraq. The 1st Armoured Division was deployed to the Gulf and commanded British forces in the area, securing areas in southern Iraq, including the city of Basra during the invasion. A total of 46,000 troops of all the British Services were committed to the operation at its start. Including were some 5,000 Royal Navy and Royal Fleet Auxiliary sailors and 4,000 Royal Marines, 26,000 British Army soldiers, and 8,100 Royal Air Force airmen.

Polish

The Battle of Umm Qasr was the first military confrontation in the Iraq War, with its objective the capture of the port.Polish GROM troops supported the amphibious assault on Umm Qasrby with the British 3 Commando Brigade of the Royal Marines, and the US 15th Marine Expeditionary Unit. After the waterway was de-mined by a Detachment from HM-14 and Naval Special Clearance Team ONE of the U.S. Navy and reopened, Umm Qasr played an important role in the shipment of humanitarian supplies to Iraqi civilians.

Australia

Australia contributed approximately 2,000 ADF personnel, including a special forces task group, three warships and 14 F/A-18 Hornet aircraft.

Summary of the invasion

The US-led Coalition forces toppled the government and captured the key cities of a large nation in only 21 days. The invasion did require a large army build-up like the 1991 Gulf War, but many didn't see combat and many were withdrawn after the invasion ended. This proved to be short-sighted, however, due to the requirement for a much larger force to combat the irregular Iraqi forces in the aftermath of the war. General Eric Shinseki, Army Chief of Staff, recommended "several hundred thousand" troops be used to maintain post-war order, but then Secretary of Defense Donald Rumsfeld—and especially his deputy, civilian Paul Wolfowitz—strongly disagreed. General Abizaid later said General Shinseki had been right.

The Iraqi army, armed mainly with Soviet-built equipment, was overall ill-equipped in comparison to the U.S. and UK forces. Attacks on U.S. supply routes by Fedayeen militiamen were repulsed. The Iraqis' artillery proved largely ineffective, and they were unable to mobilize their air force to attempt a defense. The Iraqi T-72 tanks, the heaviest armored vehicles in the Iraqi Army, were both outdated and ill-maintained, and when they were mobilized they were rapidly destroyed, thanks in part to U.S. and UK air supremacy. The U.S. Air Force, Marine Corps, Naval Aviation, and British Royal Air Force operated with impunity throughout the country, pinpointing heavily defended resistance targets and destroying them before ground troops arrived.

The main battle tanks (MBT) of the U.S. and UK forces, the U.S. M1 Abrams and British Challenger 2, proved worthy in the rapid advance across the country. With the large number of rocket propelled grenade (RPG) attacks by irregular Iraqi forces, few U.S. and UK tanks were lost and no tank crew were killed by hostile fire. The only tank loss sustained by the British Army was a Challenger 2 of the Queen's Royal Lancers that was hit by another Challenger 2, killing two crew members. All three British tank crew fatalities were a result of friendly fire.

The Iraqi Army suffered from poor morale, even amongst the elite Republican Guard. Entire units disbanded into the crowds upon the approach of invading troops, or actually sought out U.S. and UK forces out to surrender. In one case, a force of roughly 20–30 Iraqis attempted to surrender to a two-man vehicle repair and recovery team, invoking similar instances of Iraqis surrendering to news crews during the Persian Gulf War. Other Iraqi Army officers were bribed by the Central Intelligence Agency (CIA) or coerced into surrendering.

Worse, the Iraqi Army had incompetent leadership – reports state that Qusay Hussein, charged with the defense of Baghdad, dramatically shifted the positions of the two main divisions protecting Baghdad several times in the days before the arrival of U.S. forces, and as a result the units within were both confused and further demoralized when U.S. Army forces attacked. The invasion force did not see the entire Iraqi military thrown against it; U.S. and UK units had orders to move to and seize objective target-points rather than seek engagements with Iraqi units. This resulted in most regular Iraqi military units emerging from the war fully intact and without ever having been engaged by U.S. forces, especially in southern Iraq. It is assumed that most units disintegrated to either join the growing Iraqi insurgency or returned to their homes.

According to the declassified Pentagon report, "The largest contributing factor to the complete defeat of Iraq's military forces was the continued interference by Saddam." The report, designed to help U.S. officials understand in hindsight how Saddam and his military commanders prepared for and fought the invasion, paints a picture of an Iraqi government blind to the threat it faced, hampered by Saddam's inept military leadership and deceived by its own propaganda and inability to believe the United States would invade a sovereign country without provocation. According to the BBC, the report portrays Saddam Hussein as "chronically out of touch with reality - preoccupied with the prevention of domestic unrest and with the threat posed by Iran."

Security, looting and war damage

Looting took place in the days following the 2003 invasion of Iraq.

It was reported that the National Museum of Iraq was among the looted sites. Most initial news reports were that 100 percent of the museum's artifacts had been removed by looters. In fact, no more than 3 percent of its contents were removed by thieves.

An assertion that U.S. forces did not guard the museum because they were guarding the Ministry of Oil and Ministry of Interior is disputed by investigator Colonel Matthew Bogdanos in his 2005 book, "Thieves of Baghdad." Bogdanos notes that the Ministry of Oil building was bombed, but the museum complex, which took some fire, was not bombed. He also writes that Saddam Hussein's troops set up sniper's nests inside and on top of the museum, and nevertheless U.S. Marines and soldiers stayed close enough to prevent wholesale looting.

Early on, U.S. officials reacted defensively to the first, false news reports of 100 percent looting. According to U.S. officials, the "reality of the situation on the ground" was that hospitals, water plants, and ministries with vital intelligence needed security more than other sites. There were only enough U.S. troops on the ground to guard a certain number of the many sites that ideally needed protection, and so, apparently, some "hard choices" were made.

The FBI was soon called into Iraq to track down the stolen items. It was found that the initial claims of looting of substantial portions of the collection were heavily exaggerated. Initial reports claimed a near-total looting of the museum, estimated at upwards of 170,000 inventory lots, or about 501,000 pieces. The most recent estimate places the number of stolen pieces at around 15,000, and about 10,000 of them probably were taken in an "inside job" before U.S. troops arrived, according to Bogdanos. Over 5,000 looted items have since been recovered.

There has been speculation that some objects still missing were not taken by looters during the invasion, but were taken by Saddam Hussein or his government before or during the fighting. There have also been reports that early looters had keys to vaults that held rarer pieces, and some have speculated as to the pre-meditated systematic removal of key artifacts.

The National Museum of Iraq was only one of many museums and sites of cultural significance that were affected by the war. Many in the arts and antiquities communities briefed policy makers before the need to secure Iraqi museums. Despite the looting being lighter than initially feared, the cultural loss of items from ancient Sumer is significant.

More serious for the post-war state of Iraq was the looting of cached weaponry and ordnance which fueled the subsequent insurgency. As many as 250,000 tons of explosives were unaccounted for by October 2004. Disputes within the US Defense Department led to delays in the post-invasion assessment and protection of Iraqi nuclear facilities. Tuwaitha, the Iraqi site most scrutinized by UN inspectors since 1991, was left unguarded and was looted.

Zainab Bahrani, professor of Ancient Near Eastern Art History and Archaeology at Columbia University, reported that a helicopter landing pad was constructed in the heart of the ancient city of Babylon, and "removed layers of archeological earth from the site. The daily flights of the helicopters rattle the ancient walls and the winds created by their rotors blast sand against the fragile bricks. When my colleague at the site, Maryam Moussa, and I asked military personnel in charge that the helipad be shut down, the response was that it had to remain open for security reasons, for the safety of the troops."

Bahrani also reported that in the summer of 2004, "the wall of the Temple of Nabu and the roof of the Temple of Ninmah, both sixth century BC, collapsed as a result of the movement of helicopters." Electrical power is scarce in post-war Iraq, Bahrani reported, and some fragile artifacts, including the Ottoman Archive, would not survive the loss of refrigeration.

Bush declares "End of major combat operations" (May 2003)

On May 1, 2003, Bush landed on the aircraft carrier USS Abraham Lincoln, in a Lockheed S-3 Viking, where he gave a speech announcing the end of major combat operations in the Iraq war. Bush's landing was criticized by opponents as an unnecessarily theatrical and expensive stunt. Clearly visible in the background was a banner stating "Mission Accomplished." The banner, made by White House staff and supplied by request of the United States Navy, was criticized as premature. The White House subsequently released a statement that the sign and Bush's visit referred to the initial invasion of Iraq and disputing the claim of theatrics. The speech itself noted: "We have difficult work to do in Iraq. We are bringing order to parts of that country that remain dangerous."

Post-invasion Iraq has been marked by violent conflict between U.S.-led soldiers and insurgents. The ongoing resistance in Iraq was concentrated in, but not limited to, an area referred to as the Sunni triangle and Baghdad.

This resistance may be described as guerrilla warfare. The tactics in use were to include mortars, suicide bombers, roadside bombs, small arms fire, improvised explosive devices (IED's), and handheld antitank grenade-launchers (RPG's), as well as sabotage against the oil infrastructure. There were also attacks toward the power and water infrastructure.

There is evidence that some of the resistance was organized, perhaps by the fedayeen and other Saddam Hussein or Ba'ath loyalists, religious radicals, Iraqis angered by the occupation, and foreign fighters.

Fall of Baghdad-April 2003: Three weeks into the invasion, US-led Coalition forces moved into Baghdad. Units of the Iraqi Special Republican Guard led the defence of the city. The rest of the defenders were a mixture of Republican Guard units, Regular army units, Iraqi Fedayeen, and non-Iraqi Arab volunteers. Initial plans were for Coalition units to surround the city and gradually move in, forcing Iraqi armor and ground units to cluster into a central pocket in the city, and then attack with air and artillery forces.

This plan soon became unnecessary, as an initial engagement of armored units south of the city saw most of the Republican Guard's assets destroyed and routes in the southern outskirts of the city occupied. On April 5 Task Force 1-64 Armor of the U.S. Army's Third Infantry Division executed a raid, later called the "Thunder Run", to test remaining Iraqi defenses, with 29 tanks and 14 Bradley Armored Fighting Vehicles advancing to the Baghdad airport.

They met heavy resistance, but were successful in reaching the airport. US troops faced heavy fighting in the airport, and were even temporarily pushed out, but eventually secured the airport. The next day, another brigade of the 3rd I.D. attacked into downtown Baghdad and occupied one of the palaces of Saddam Hussein in fierce fighting. US Marines also faced heavy shelling from Iraqi artillery as they attempted to cross a river bridge. The Iraqi commander directed the fire, and one shell from an Iraqi gun killed or wounded four Marines, but the river crossing was successful. The Iraqis managed to inflict heavy casualties on the American forces near the airport from defensive positions but suffered severe casualties from air bombardment.

Within hours of the palace seizure and with television coverage of this spreading through Iraq, U.S. forces ordered Iraqi forces within Baghdad to surrender, or the city would face a full-scale assault. Iraqi government officials had either disappeared or had conceded defeat, and on April 9, 2003, Baghdad was formally occupied by Coalition forces. Much of Baghdad remained unsecured however, and fighting continued within the city and its outskirts well into the period of occupation. Saddam had vanished, and his whereabouts were unknown.

On April 10, a rumor emerged that Saddam Hussein and his top aides were in a mosque complex in the Al Az'Amiyah District of Baghdad. Three Companies of Marines were sent to capture him. The Marines came under heavy fire from rocket-propelled grenades, mortars, and assault rifles. One Marine was killed and 20 were wounded, but neither Saddam or any of his top aides were found.

U.S. forces supported by mortars, artillery, and aircraft continued to attack Iraqi forces still loyal to Saddam Hussein and non-Iraqi Arab volunteers. U.S. aircraft flying in support were met with Iraqi anti-aircraft fire. On April 12, the final resistance to U.S. forces was mounted. One Marine was killed, but by late afternoon, all fighting had ceased. A total of 34 U.S. soldiers and 2,320 Iraqi soldiers and Fedayeen were killed.

Many Iraqis celebrated the downfall of Saddam by vandalizing the many portraits and statues of him together with other pieces of his cult of personality. One widely publicized event was the dramatic toppling of a large statue of Saddam in Baghdad's Fardus Square. This attracted considerable media coverage at the time. As the British Daily Mirror reported,

"For an oppressed people this final act in the fading daylight, the wrenching down of this ghastly symbol of the regime, is their Berlin Wall moment. Big Moustache has had his day."

As Staff Sergeant Brian Plesich reported in On Point: The United States Army in Operation Iraqi Freedom,

"The Marine Corps colonel in the area saw the Saddam statue as a target of opportunity and decided that the statue must come down. Since we were right there, we chimed in with some loudspeaker support to let the Iraqis know what it was we were attempting to do..." "Somehow along the way, somebody had gotten the idea to put a bunch of Iraqi kids onto the wrecker that was to pull the statue down. While the wrecker was pulling the statue down, there were Iraqi children crawling all over it. Finally they brought the statue down"

The fall of Baghdad saw the outbreak of regional, sectarian violence throughout the country, as Iraqi tribes and cities began to fight each other over old grudges. The Iraqi cities of Al-Kut and Nasiriyah launched attacks on each other immediately following the fall of Baghdad to establish dominance in the new country, and the US-led Coalition quickly found themselves embroiled in a potential civil war. US-led Coalition forces ordered the cities to cease hostilities immediately, explaining that Baghdad would remain the capital of the new Iraqi government. Nasiriyah responded favorably and quickly backed down; however, Al-Kut placed snipers on the main roadways into town, with orders that invading forces were not to enter the city. After several minor skirmishes, the snipers were removed, but tensions and violence between regional, city, tribal, and familial groups continued.

US General Tommy Franks assumed control of Iraq as the supreme commander of the coalition occupation forces. Shortly after the sudden collapse of the defense of Baghdad, rumors were circulating in Iraq and elsewhere that there had been a deal struck (a "safqua") wherein the US-led Coalition had bribed key members of the Iraqi military elite and/or the Ba'ath party itself to stand down. In May 2003, General Franks retired, and confirmed in an interview with Defense Week that the US-led Coalition had paid Iraqi military leaders to defect. The extent of the defections and their effect on the war are unclear.

US-led Coalition troops promptly began searching for the key members of Saddam Hussein's government. These individuals were identified by a variety of means, most famously through sets of most-wanted Iraqi playing cards.

On July 22, 2003 during a raid by the U.S. 101st Airborne Division and men from Task Force 20, Saddam Hussein's sons Uday and Qusay, and one of his grandsons were killed in a massive fire-fight.

Saddam Hussein was captured on December 13, 2003 by the U.S. Army's 4th Infantry Division and members of Task Force 121 during Operation Red Dawn.

Special Operations: The 2nd Battalion of the U.S. 5th Special Forces Group, United States Army Special Forces (Green Berets) conducted reconnaissance in the cities of Basra, Karbala and various other locations.

In the North, the 10th Special Forces Group (10th SFG) and CIA paramilitary officers from their Special Activities Division had the mission of aiding the Kurdish parties, the Patriotic Union of Kurdistan and the Kurdistan Democratic Party, de facto rulers of Iraqi Kurdistan since 1991, and employing them against the 13 Iraqi Divisions located near Kirkuk and Mosul. Turkey had officially prohibited any Coalition troops from using their bases or airspace, so lead elements of the 10th SFG had to make a detour infiltration; their flight was supposed to take four hours but instead took ten.

Hours after the first of such flights, Turkey did allow the use of its air space and the rest of the 10th SFG infiltrated in. The preliminary mission was to destroy the base of the Kurdish terrorist group Ansar al-Islam, believed to be linked to Al Qaeda. Concurrent and follow-on missions involved attacking and fixing Iraqi forces in the north, thus preventing their deployment to the southern front and the main effort of the invasion.

On March 26, 2003, the 173rd Airborne Brigade augmented the invasion's northern front by parachuting into northern Iraq onto Bashur Airfield, controlled at the time by elements of 10th SFG and Kurdish peshmerga. The fall of Kirkuk on April 10, 2003 to the 10th SFG, CIA Paramilitary Teams and Kurdish peshmerga precipitated the 173rd's planned assault, preventing the unit's involvement in combat against Iraqi forces during the invasion.

The successful occupation of Kirkuk came as a result of approximately two weeks of fighting that included the Battle of the Green Line (the unofficial border of the Kurdish autonomous zone) and the subsequent Battle of Kani Domlan Ridge (the ridgeline running northwest to southeast of Kirkuk), the latter fought exclusively by 3rd Battalion, 10th SFG and Kurdish peshmerga against the Iraqi I Corps. The 173rd Brigade would eventually take responsibility for Kirkuk days later, becoming involved in the counterinsurgency fight and remain there until redeploying a year later.

Further reinforcing operations in Northern Iraq, the 26th Marine Expeditionary Unit (Special Operations Capable), serving as Landing Force Sixth Fleet, deployed in April to Erbil and subsequently Mosul via Marine KC-130 flights. The 26 MEU(SOC) maintained security of the Mosul airfield and surrounding area until relief by the 101st Airborne Division.

After Sargat was taken, Bravo Company, 3rd Battalion, 10th SFG and CIA paramilitary officers along with their Kurdish allies pushed south towards Tikrit and the surrounding towns of Northern Iraq. Previously, during the Battle of the Green Line, Bravo Company, 3/10 with their Kurdish allies pushed back, destroyed, or routed the 13th Iraqi Infantry Division. The same company took Tikrit. Iraq was the largest deployment of Special Forces since Vietnam.

The Karbala Gap was a 20-25-mile wide strip of land with the Euphrates River to the east and Lake Razazah to the west. This strip of land was recognized by Iraqi commanders as a key approach to Baghdad, and was defended by some of the best units of the Iraqi Republican Guard. The Iraqi high command had originally positioned two Republican Guard divisions blocking the Karbala Gap. Here these forces suffered heavy Coalition air attacks. However, the Coalition had since the beginning of March been conducting a strategic deception operation to convince the Iraqis that the US 4th Infantry Division would be mounting a major assault into northern Iraq from Turkey.

This deception plan worked, and on April 2 Saddam's son Qusay Hussein declared that the American invasion from the south was a feint and ordered troops to be re-deployed from the Karbala front to the north of Baghdad. Lt. Gen. Raad al-Hamdani, who was in command of the Karbala region, protested this and argued that unless reinforcements were rushed to the Karbala gap immediately to prevent a breach, American troops would reach Baghdad within 48 hours, but his suggestions fell on deaf ears. American troops rushed through the gap and reached the Euphrates River at the town of Musayib. At Musayib, American troops crossed the Euphrates in boats and seized the vital al-Kaed bridge across the Euphrates after Iraqi demolitions teams had failed to destroy it in time.

The 10th Armored Brigade from the Medina Division and the 22nd Armored Brigade from the Nebuchadnezzar Division, supported by artillery, launched night attacks against the American bridgehead at Musayib. The attack was savagely repulsed using tank fire and massed artillery rockets, destroying or disabling every Iraqi tank in the assault. The next morning, Coalition aircraft and helicopters rained death on the Republican Guard units, destroying many more vehicles as well as communications infrastructure. The Republican Guard units broke under the massed firepower and lost any sense of command and cohesion and the American forces poured through gap on to Baghdad

The Iraqi port city of Umm Qasr was the first British obstacle. A joint Polish-British-American force ran into unexpectedly stiff resistance, and it took several days to clear the Iraqi forces out. Fourteen Coalition soldiers and 30 Iraqi soldiers were killed. Farther north, the British 7 Armoured Brigade ('The Desert Rats'), fought their way into Iraq's second-largest city, Basra, on April 6, coming under constant attack by regulars and Fedayeen, while 3rd Battalion, The Parachute Regiment (the British Red Devils) cleared the 'old quarter' of the city that was inaccessible to vehicles. Entering Basra was achieved after two weeks of fierce fighting, which included the biggest tank battle by British forces since World War II when the Royal Scots Dragoon Guards destroyed 14 Iraqi tanks on 27 March.

Elements of 1 (UK) Armoured Division began to advance north towards U.S. positions around Al Amarah on April 9. Pre-existing electrical and water shortages continued throughout the conflict and looting began as Iraqi forces collapsed. While Coalition forces began working with local Iraqi Police to enforce order, a joint team composed of Royal Engineers and the Royal Logistics Corps of the British Army rapidly set up and repaired dockyard facilities to allow humanitarian aid to begin to arrive from ships arriving in the port city of Umm Qasr.

After a rapid initial advance, the first major pause occurred near Karbala. There, U.S. Army elements met resistance from Iraqi troops defending cities and key bridges along the Euphrates River. These forces threatened to interdict supply routes as American forces moved north. Eventually, troops from the 101st Airborne Division of the U.S Army secured the cities of Najaf and Karbala to prevent any Iraqi counterattacks on the 3rd Infantry Division's lines of communication as the division pressed its advance toward Baghdad.

A total of 11 British soldiers were killed, while 395-515 Iraqi soldiers, irregulars, and Fedayeen were killed.

The Battle of Najaf was a major battle in the 2003 invasion of Iraq. The first stage of the battle was fought when the US 3rd Infantry Division fought to surround the town. The second stage was fought when soldiers from the U.S. 101st Airborne Division fought to clear and secure the city.

The Battle of Najaf started with American AH-64 Apache helicopter gunships setting out on a mission to attack Republican Guard armored units, and while flying low, came under heavy anti-aircraft, small arms, and RPG fire which disrupted the attack and led to one of the gunships down and many heavily damaged. They attacked again successfully on March 26, this time after a pre-mission artillery barrage and with support from F/A-18 Hornet jets, with no gunships lost.

The 1st Brigade Combat Team's air defense battery moved in and after heavy fighting with entrenched Iraqi Fedayeen seized a strategic bridge in Najaf, known as "Objective Jenkins". They then came under fierce counter attacks by Iraqi forces and Fedayeen, but they failed to dislodge U.S. forces from their positions. After 36 hours of combat at the bridge at Najaf, the Iraqis were defeated, and the key bridge was secured, isolating Najaf from the north.

The 101st Airborne Division on March 29, supported by a battalion from the 1st Armored Division attacked Iraqi forces in the southern part of the city, near the Imam Ali Mosque and captured Najaf's airfield. However, four Americans were killed by a suicide bomber. Then on March 31, the 101st launched a attack with a reconnaissance-in-force into Najaf and on April 1, elements of the 70th Armored Regiment launched a "Thunder Run", a armored thrust through Najaf's city center and after several days of heavy fighting and with air support was able to defeat the Iraqi forces, slowly securing the city by April 4. The Iraqis had suffered hundreds of casualties during the battle.

Iraq War 2003-Battle of Nasiriyah: Initially, the U.S. 1st Marine Division fought through the Rumaila oil fields, and moved north to Nasiriyah—a moderate-sized, Shi'ite dominated city with important strategic significance as a major road junction and its proximity to nearby Talil Airfield. It was also situated near a number of strategically important bridges over the Euphrates River. The city was defended by a mix of regular Iraqi army units, Ba'ath loyalists, and Fedayeen from both Iraq and abroad. The United States Army 3rd Infantry Division defeated Iraqi forces entrenched in and around the airfield and bypassed the city to the west.

On March 23, a convoy from the 3rd Infantry Division, including the female American soldiers Jessica Lynch and Lori Piestewa, was ambushed after taking a wrong turn into the city. Eleven U.S. soldiers were killed, and seven, including Lynch and Piestewa, were captured. Piestewa died of wounds shortly after capture, while the remaining five prisoners of war were later rescued. Piestewa, who was from Tuba City, Arizona, and an enrolled member of the Hopi Tribe, was believed to have been the first Native American woman killed in combat in a foreign war.

On the same day, U.S Marines entered Nasiriyah in force, facing heavy resistance as they moved to secure two major bridges in the city. Several Marines were killed during a firefight with Fedayeen in the urban fighting. At the Saddam Canal, another 18 Marines were killed in heavy fighting with Iraqi soldiers. An Air Force A-10 was involved in a case of friendly fire that resulted in the death of six Marines when it accidentally attacked an American amphibious vehicle. Two other vehicles were destroyed when a barrage of RPG and small arms fire killed most of the Marines inside.

A Marine from Marine Air Control Group 28 was killed by enemy fire, and two Marine engineers drowned in the Saddam Canal. On the evening of March 24, a battalion of the 1st Marine Regiment pushed through Nasiriyah and established a perimeter 15 kilometers (9.3 miles) north of the city. Iraqi reinforcements from Kut launched several counterattacks. The Marines managed to repel them using indirect fire and close air support. The last Iraqi attack was beaten off at dawn. The battalion estimated that 200-300 Iraqi soldiers were killed, without a single American casualty. Nasiriyah was declared secure, but attacks by Iraqi Fedayeen continued. These attacks were uncoordinated, and resulted in firefights in which large numbers of Fedayeen were killed. Because of Nasiriyah's strategic position as a road junction, a significant gridlock occurred as U.S. forces moving north converged on the city's surrounding highways.

With the Nasiriyah and Talil Airfields secured, Coalition forces gained an important logistical center in southern Iraq and established FOB/EAF Jalibah, some 10 miles (16 km) outside of Nasiriyah. Additional troops and supplies were soon brought through this forward operating base. The 101st Airborne Division continued its attack north in support of the 3rd Infantry Division.

By 27 March 28, a severe sand storm slowed the Coalition advance as the 3rd Infantry Division halted its northward drive half way between Najaf and Karbala. As a result of heavy rains that occurred along with the sand storm, orange-colored mud fell on some parts of the invasion force in the area. Air operations by helicopters, poised to bring reinforcements from the 101st Airborne, were blocked for three days. There was particularly heavy fighting in and around the bridge near the town of Kufl.

Opening Attack of Iraq War: On March 20, 2003 at approximately 02:30 UTC or about 90 minutes after the lapse of the 48-hour deadline, at 05:33 local time, explosions were heard in Baghdad. Special operations commandos from the CIA's Special Activities Division from the Northern Iraq Liaison Element infiltrated throughout Iraq and called in the early air strikes. At 03:15 UTC, or 10:15 p.m. EST, George W. Bush announced that he had ordered an "attack of opportunity" against targets in Iraq. When this word was given, the troops on standby crossed the border into Iraq.

Before the invasion, many observers had expected a lengthy campaign of aerial bombing before any ground action, taking as examples the 1991 Persian Gulf War or the 2001 invasion of Afghanistan. In practice, U.S. plans envisioned simultaneous air and ground assaults to decapitate the Iraqi forces quickly (Shock and Awe), attempting to bypass Iraqi military units and cities in most cases. The assumption was that superior mobility and coordination of Coalition forces would allow them to attack the heart of the Iraqi command structure and destroy it in a short time, and that this would minimize civilian deaths and damage to infrastructure. It was expected that the elimination of the leadership would lead to the collapse of the Iraqi Forces and the government, and that much of the population would support the invaders once the government had been weakened. Occupation of cities and attacks on peripheral military units were viewed as undesirable distractions.

Following Turkey's decision to deny any official use of its territory, the Coalition was forced to modify the planned simultaneous attack from north and south. Special Operations forces from the CIA and US Army managed to build and lead the Kurdish Peshmerga into an effective force and assault for the North. The primary bases for the invasion were in Kuwait and other Persian Gulf nations. One result of this was that one of the divisions intended for the invasion was forced to relocate and was unable to take part in the invasion until well into the war. Many observers felt that the Coalition devoted sufficient numbers of troops to the invasion, but too many were withdrawn after it ended, and that the failure to occupy cities put them at a major disadvantage in achieving security and order throughout the country when local support failed to meet expectations.

The invasion was swift, leading to the collapse of the Iraqi government and the military of Iraq in about three weeks. The oil infrastructure of Iraq was rapidly seized and secured with limited damage in that time. Securing the oil infrastructure was considered of great importance. In the Persian Gulf War, while retreating from Kuwait, the Iraqi army had set many oil wells on fire, in an attempt to disguise troop movements and to distract Coalition forces. Before the 2003 invasion, Iraqi forces had mined some 400 oil wells around Basra and the Al-Faw peninsula with explosives. Coalition troops launched an air and amphibious assault on the Al-Faw peninsula during the closing hours of March 20 to secure the oil fields there; the amphibious assault was supported by warships of the Royal Navy, Polish Navy, and Royal Australian Navy.

The United States Marine Corps' 15th Marine Expeditionary Unit, attached to the British 3 Commando Brigade and the Polish Special Forces unit GROM attacked the port of Umm Qasr. There they met with heavy resistance by Iraqi troops. A total of 14 Coalition troops and 30-40 Iraqi troops were killed, and 450 Iraqis taken prisoner. The British Army's 16 Air Assault Brigade also secured the oil fields in southern Iraq in places like Rumaila while the Polish commandos captured offshore oil platforms near the port, preventing their destruction. Despite the rapid advance of the invasion forces, some 44 oil wells were destroyed and set ablaze by Iraqi explosives or by incidental fire. However, the wells were quickly capped and the fires put out, preventing the ecological damage and loss of oil production capacity that had occurred at the end of the Persian Gulf War.

In keeping with the rapid advance plan, the U.S. 3rd Infantry Division moved westward and then northward through the western desert toward Baghdad, while the 1st Marine Expeditionary Force moved along Highway 1 through the center of the country, and 1 (UK) Armoured Division moved northward through the eastern marshland.

During the first week of the war, Iraqi forces fired a Scud missile at the American Battlefield Update Assessment center in Camp Doha, Kuwait. The missile was intercepted and shot down by a Patriot missile seconds before hitting the complex. Subsequently, two A-10 Warthogs bombed the missile launcher.

2003 Iraq War: The early morning of March 19, 2003, U.S. forces abandoned the plan for initial, non-nuclear decapitation strikes against fifty-five top Iraqi officials, in light of reports that Saddam Hussein was visiting his daughters and sons, Uday and Qusay at Dora Farms, within the al-Dora farming community on the outskirts of Baghdad. At approximately 05:30 UTC two F-117 Nighthawks from the 8th Expeditionary Fighter Squadron dropped four enhanced, satellite-guided 2,000-pound Bunker Busters GBU-27 on the compound. Complementing the aerial bombardment were nearly 40 Tomahawk cruise missiles fired from at least four ships, including the Arleigh Burke class destroyer, the USS Donald Cook, and two submarines in the Red Sea and Persian Gulf.

One missed the compound entirely and the other three missed their target landing on the other side of the wall of the palace compound. Saddam Hussein was not present nor were any members of the Iraqi leadership or Hussein family. The attack killed one civilian and injured fourteen others, including nine women and one child. Later investigation revealed that Saddam Hussein had not visited the farm since 1995.

Iraq War 2003: Since the 1991 Persian Gulf War, the U.S. and UK had been engaged in low-level attacks on Iraqi air defenses which targeted them while enforcing Iraqi no-fly zones. These zones, and the attacks to enforce them, were described as illegal by the former UN Secretary General, Boutros Boutros-Ghali and the then French foreign minister, Hubert Vedrine. Other countries, notably Russia and China, also condemned the zones as a violation of Iraqi sovereignty. In mid-2002, the U.S. began more carefully selecting targets in the southern part of the country to disrupt the military command structure in Iraq. A change in enforcement tactics was acknowledged at the time, but it was not made public that this was part of a plan known as Operation Southern Focus.

The amount of ordnance dropped on Iraqi positions by Coalition aircraft in 2001 and 2002 was less than in 1999 and 2000 which was during the Clinton administration. This information has been used to attempt to refute the theory that the Bush administration had already decided to go to war against Iraq before coming to office and that the bombing during 2001 and 2002 was laying the groundwork for the eventual invasion in 2003. However, information obtained by the UK Liberal Democrats showed that the UK dropped twice as many bombs on Iraq in the second half of 2002 as they did during the whole of 2001. The tonnage of UK bombs dropped increased from 0 in March 2002 and 0.3 in April 2002 to between 7 and 14 tons per month in May–August, reaching a pre-war peak of 54.6 tons in September – before Congress' October 11 authorization of the invasion.

The September 5 attacks included a 100+ aircraft attack on the main air defense site in western Iraq. According to an editorial in New Statesman this was "Located at the furthest extreme of the southern no-fly zone, far away from the areas that needed to be patrolled to prevent attacks on the Shias, it was destroyed not because it was a threat to the patrols, but to allow allied special forces operating from Jordan to enter Iraq undetected."

Tommy Franks, who commanded the invasion of Iraq, has since admitted that the bombing was designed to “degrade” Iraqi air defences in the same way as the air attacks that began the 1991 Gulf War. These "spikes of activity" were, in the words of then British Defence Secretary, Geoff Hoon, designed to 'put pressure on the Iraqi regime' or, as The Times reported, to "provoke Saddam Hussein into giving the allies an excuse for war". In this respect, as provocations designed to start a war, leaked British Foreign Office legal advice concluded that such attacks were illegal under international law.

Another attempt at provoking the war was mentioned in a leaked memo from a meeting between George W. Bush and Tony Blair on January 31, 2003 at which Bush allegedly told Blair that "The US was thinking of flying U2 reconnaissance aircraft with fighter cover over Iraq, painted in UN colours. If Saddam fired on them, he would be in breach." The Nuremberg Trials concluded that premeditated attacks on sovereign countries is aggression, the ultimate war crime.

United States military operations were conducted under the codename Operation Iraqi Liberation (OIL). The codename was later changed to Operation Iraqi Freedom, due to the unfortunate acronym. The United Kingdom military operation was named Operation Telic.

Multilateral support

In November 2002, President George W. Bush, visiting Europe for a NATO summit, declared that, "should Iraqi President Saddam Hussein choose not to disarm, the United States will lead a coalition of the willing to disarm him."

Thereafter, the Bush administration briefly used the term Coalition of the Willing to refer to the countries who supported, militarily or verbally, the military action in Iraq and subsequent military presence in post-invasion Iraq since 2003. The original list prepared in March 2003 included 49 members. Of those 49, only six besides the U.S. contributed troops to the invasion force (the United Kingdom, Spain, Australia, Poland, Portugal, and Denmark), 33 provided some number of troops to support the occupation after the invasion was complete. Six members have no military.

Invasion force

Approximately 248,000 soldiers from the United States, 45,000 British soldiers, 2,000 Australian soldiers and 194 Polish soldiers from Special Forces unit GROM were sent to Kuwait for the invasion. The invasion force was also supported by Iraqi Kurdish militia troops, estimated to number upwards of 70,000. In the latter stages of the invasion 620 troops of the Iraqi National Congress opposition group were deployed to southern Iraq.

A U.S. Central Command, Combined Forces Air Component Commander report, indicated that as of April 30, 2003, there were a total of 466,985 U.S. personnel deployed for Operation Iraqi Freedom. This included USAF, 54,955; USAF Reserve, 2,084; Air National Guard, 7,207; USMC, 74,405; USMC Reserve, 9,501; USN, 61,296 (681 are members of the U.S. Coast Guard); USN Reserve, 2,056; and US Army, 233,342; US Army Reserve, 10,683; and Army National Guard, 8,866.

Plans for opening a second front in the north were severely hampered when Turkey refused the use of its territory for such purposes. In response to Turkey's decision, the United States dropped several thousand paratroopers from the 173rd Airborne Brigade into northern Iraq, a number significantly less than the 15,000 strong 4th Mechanized Infantry Division that the U.S. originally planned to use for opening the northern front.

Operation Iraqi Freedom Preparation

CIA Special Activities Division (SAD) Paramilitary teams entered Iraq in July 2002 before the 2003 invasion. Once on the ground they prepared for the subsequent arrival of US military forces. SAD teams then combined with US Army Special Forces to organize the Kurdish Peshmerga. This joint team combined to defeat Ansar al-Islam, an ally of Al Qaida, in a battle in the northeast corner of Iraq. The US side was carried out by Paramilitary Officers from SAD and the Army's 10th Special Forces Group.

SAD teams also conducted high risk special reconnaissance missions behind Iraqi lines to identify senior leadership targets. These missions led to the initial strikes against Saddam Hussein and his key generals. Although the initial strike against Hussein was unsuccessful in killing the dictator, it was successful in effectively ending his ability to command and control his forces. Other strikes against key generals were successful and significantly degraded the command's ability to react to and maneuver against the US-led invasion force coming from the south.

SAD operations officers were also successful in convincing key Iraqi Army officers to surrender their units once the fighting started and/or not to oppose the invasion force. NATO member Turkey refused to allow its territory to be used for the invasion. As a result, the SAD/SOG and US Army Special Forces joint teams and the Kurdish Peshmerga were the entire northern force against government forces during the invasion. Their efforts kept the 5th Corps of the Iraqi army in place to defend against the Kurds rather than their moving to contest the coalition force.

According to General Tommy Franks, April Fool, an American officer working undercover as a diplomat, was approached by an Iraqi intelligence agent. April Fool then sold to the Iraqi false "top secret" invasion plans provided by Franks' team. This decoy deception successfully misled the Iraqi military into deploying major forces in Northern and Western Iraq in anticipation of attacks by way of Turkey or Jordan, which never took place. This greatly reduced the defensive capacity in the rest of Iraq and significantly facilitated the actual attacks via Kuwait and the Persian Gulf in the southeast.

Defending force

The number of personnel in the Iraqi military prior to the war was uncertain, but it was believed to have been poorly equipped. The International Institute for Strategic Studies estimated the Iraqi armed forces to number 538,000 (Iraqi Army 375,000, Iraqi Navy 2,000, Iraqi Air Force 20,000 and air defense 17,000), the paramilitary Fedayeen Saddam 44,000, Republican Guard 80,000 and reserves 650,000.

Another estimate numbers the army and Republican Guard at between 280,000 to 350,000 and 50,000 to 80,000, respectively, and the paramilitary between 20,000 and 40,000. There were an estimated thirteen infantry divisions, ten mechanized and armored divisions, as well as some special forces units. The Iraqi Air Force and Iraqi Navy played a negligible role in the conflict.

During the invasion, Iraqi forces, along with foreign volunteers from Syria, traveled to Iraq and took part in the fighting, usually under the command of the Saddam Fedayeen. It is not known for certain how many foreign fighters fought in Iraq in 2003, however, intelligence officers of the U.S. First Marine Division estimated that 50% of all Iraqi combatants in central Iraq were foreigners.

In addition, the terrorist group Ansar al-Islam controlled a small section of northern Iraq in an area outside of Saddam Hussein's control. Ansar al-Islam had been fighting against Kurdish forces since 2001. At the time of the invasion they fielded approximately 600 to 800 fighters. Ansar al-Islam was led by the Jordanian-born militant Abu Musab al-Zarqawi, who would later become an important leader in the Iraqi insurgency. Ansar al-Islam was driven out of Iraq in late March by a joint American-Kurdish force during Operation Viking Hammer.

The Authorization for Use of Military Force Against Iraq Resolution of 2002 was passed by congress with Democrats voting 58% in favor in the Senate, and 39% in favor in the House. Republicans supported the joint resolution 98% and 97% in the Senate and House respectively. The resolution asserts the authorization by the Constitution of the United States and the Congress for the President to fight anti-United States terrorism. Citing the Iraq Liberation Act of 1998, the resolution reiterated that it should be the policy of the United States to remove the Saddam Hussein regime and promote a democratic replacement.

The resolution "supported" and "encouraged" diplomatic efforts by President George W. Bush to "strictly enforce through the U.N. Security Council all relevant Security Council resolutions regarding Iraq" and "obtain prompt and decisive action by the Security Council to ensure that Iraq abandons its strategy of delay, evasion, and noncompliance and promptly and strictly complies with all relevant Security Council resolutions regarding Iraq." The resolution authorized President Bush to use the Armed Forces of the United States "as he determines to be necessary and appropriate" to "defend the national security of the United States against the continuing threat posed by Iraq; and enforce all relevant United Nations Security Council Resolutions regarding Iraq."

The legality of the invasion of Iraq has been challenged since its inception on a number of fronts, and several prominent supporters of the invasion in all the invading nations have publicly and privately cast doubt on its legality. It is claimed that the invasion was fully legal because authorization was implied by the United Nations Security Council. International legal experts, including the International Commission of Jurists, a group of 31 leading Canadian law professors, and the U.S.-based Lawyers Committee on Nuclear Policy, have denounced both of these rationales.

On Thursday November 20, 2003, an article published in the Guardian alleged that Richard Perle, a senior member of the administration's Defense Policy Board Advisory Committee, conceded that the invasion was illegal but still justified.

The United Nations Security Council has passed nearly 60 resolutions on Iraq and Kuwait since Iraq's invasion of Kuwait in 1990. The most relevant to this issue is Resolution 678, passed on November 29, 1990. It authorizes "member states co-operating with the Government of Kuwait... to use all necessary means" to (1) implement Security Council Resolution 660 and other resolutions calling for the end of Iraq's occupation of Kuwait and withdrawal of Iraqi forces from Kuwaiti territory and (2) "restore international peace and security in the area." Resolution 678 has not been rescinded or nullified by succeeding resolutions and Iraq was not alleged after 1991 to invade Kuwait or to threaten do so.

Resolution 1441 was most prominent during the run up to the war and formed the main backdrop for Secretary of State Colin Powell's address to the Security Council one month before the invasion. According to an independent commission of inquiry set up by the government of the Netherlands, UN resolution 1441 "cannot reasonably be interpreted (as the Dutch government did) as authorising individual member states to use military force to compel Iraq to comply with the Security Council's resolutions." Accordingly, the Dutch commission concluded that the 2003 invasion violated international law.

At the same time, Bush Administration officials advanced a parallel legal argument using the earlier resolutions, which authorized force in response to Iraq's 1990 invasion of Kuwait. Under this reasoning, by failing to disarm and submit to weapons inspections, Iraq was in violation of U.N. Security Council Resolutions 660 and 678, and the U.S. could legally compel Iraq's compliance through military means.

Critics and proponents of the legal rationale based on the U.N. resolutions argue that the legal right to determine how to enforce its resolutions lies with the Security Council alone, not with individual nations.

In February 2006, Luis Moreno Ocampo, the lead prosecutor for the International Criminal Court, reported that he had received 240 separate communications regarding the legality of the war, many of which concerned British participation in the invasion. In a letter addressed to the complainants, Mr. Moreno Ocampo explained that he could only consider issues related to conduct during the war and not to its underlying legality as a possible crime of aggression because no provision had yet been adopted which "defines the crime and sets out the conditions under which the Court may exercise jurisdiction with respect to it." In a March 2007 interview with the Sunday Telegraph, Moreno Ocampo encouraged Iraq to sign up with the court so that it could bring cases related to alleged war crimes.

United States Ohio Congressman Dennis Kucinich held a press conference on the evening of April 24, 2007, revealing US House Resolution 333 and the three articles of impeachment against Vice President Dick Cheney. He charges Cheney with manipulating the evidence of Iraq's weapons program, deceiving the nation about Iraq's connection to al-Qaeda, and threatening aggression against Iran in violation of the United Nations Charter.

George Bush, speaking in October 2002, said that “The stated policy of the United States is regime change… However, if Hussein were to meet all the conditions of the United Nations, the conditions that I have described very clearly in terms that everybody can understand, that in itself will signal the regime has changed”. Based on claims from certain intelligence sources, Bush stated on March 6, 2003 that he believed that Hussein was not complying with UN Resolution 1441.

In September 2002, Tony Blair stated, in an answer to a parliamentary question, that “Regime change in Iraq would be a wonderful thing. That is not the purpose of our action; our purpose is to disarm Iraq of weapons of mass destruction” In November of that year, Blair further stated that, “So far as our objective, it is disarmament, not régime change - that is our objective. Now I happen to believe the regime of Saddam is a very brutal and repressive regime, I think it does enormous damage to the Iraqi people... so I have got no doubt Saddam is very bad for Iraq, but on the other hand I have got no doubt either that the purpose of our challenge from the United Nations is disarmament of weapons of mass destruction, it is not regime change.”

At a press conference on January 31, 2003, Bush again reiterated that the single trigger for the invasion would be Iraq’s failure to disarm, “Saddam Hussein must understand that if he does not disarm, for the sake of peace, we, along with others, will go disarm Saddam Hussein.” As late as February 25, 2003, it was still the official line that the only cause of invasion would be a failure to disarm. As Blair made clear in a statement to the House of Commons, “I detest his regime. But even now he can save it by complying with the UN's demand. Even now, we are prepared to go the extra step to achieve disarmament peacefully.”

Additional justifications used at various times included Iraqi violation of UN resolutions, the Iraqi government's repression of its citizens, and Iraqi violations of the 1991 cease-fire.

The main allegations were that Hussein possessed or was attempting to produce weapons of mass destruction which Saddam Hussein, had used such as in Halabja, possessed, and made efforts to acquire. Particularly considering two previous attacks on Baghdad nuclear weapons production facilities by both Iran and Israel which was alleged to have postponed weapons development progress. And that he had ties to terrorists, specifically al-Qaeda.

While it never made an explicit connection between Iraq and the September 11 attacks, the George W. Bush administration repeatedly insinuated a link, thereby creating a false impression for the US public. Grand jury testimony from the 1993 World Trade Center attack trials cited numerous direct linkages from the bombers to Baghdad and Department 13 of the Iraqi Intelligence Service in that initial attack marking the second anniversary to vindicate the surrender of Iraqi armed forces in Operation Desert Storm. For example, The Washington Post has noted that,

“

While not explicitly declaring Iraqi culpability in the September 11, 2001, terrorist attacks, administration officials did, at various times, imply a link. In late 2001, Cheney said it was "pretty well confirmed" that attack mastermind Mohamed Atta had met with a senior Iraqi intelligence official. Later, Cheney called Iraq the "geographic base of the terrorists who had us under assault now for many years, but most especially on 9/11."

”

Steven Kull, director of the Program on International Policy Attitudes (PIPA) at the University of Maryland, observed in March 2003 that "The administration has succeeded in creating a sense that there is some connection [between Sept. 11 and Saddam Hussein]". This was following a New York Times/CBS poll that showed 45% of Americans believing Saddam Hussein was "personally involved" in the September 11 atrocities. As the Christian Science Monitor observed at the time, while "Sources knowledgeable about US intelligence say there is no evidence that Hussein played a role in the Sept. 11 attacks, nor that he has been or is currently aiding Al Qaeda... the White House appears to be encouraging this false impression, as it seeks to maintain American support for a possible war against Iraq and demonstrate seriousness of purpose to Hussein's regime." The CSM went on to report that, while polling data collected "right after Sept. 11, 2001" showed that only 3 percent mentioned Iraq or Saddam Hussein, by January 2003 attitudes "had been transformed" with a Knight Ridder poll showing that 44% of Americans believed "most" or "some" of the September 11 hijackers were Iraqi citizens.

The BBC has also noted that while President Bush, "never directly accused the former Iraqi leader of having a hand in the attacks on New York and Washington", he, "repeatedly associated the two in keynote addresses delivered since September 11", adding that, "Senior members of his administration have similarly conflated the two." For instance, the BBC report quotes Colin Powell in February 2003, stating that, "We've learned that Iraq has trained al-Qaeda members in bomb-making and poisons and deadly gases. And we know that after September 11, Saddam Hussein's regime gleefully celebrated the terrorist attacks on America." The same BBC report also noted the results of a recent opinion poll, which suggested that "70% of Americans believe the Iraqi leader was personally involved in the attacks."

Also in September 2003, the Boston Globe reported that "Vice President Dick Cheney, anxious to defend the White House foreign policy amid ongoing violence in Iraq, stunned intelligence analysts and even members of his own administration this week by failing to dismiss a widely discredited claim: that Saddam Hussein might have played a role in the Sept. 11 attacks." A year later, presidential candidate John Kerry alleged that Cheney was continuing "to intentionally mislead the American public by drawing a link between Saddam Hussein and 9/11 in an attempt to make the invasion of Iraq part of the global war on terror."

Throughout 2002, the Bush administration insisted that removing Hussein from power to restore international peace and security was a major goal. The principal stated justifications for this policy of "regime change" were that Iraq's continuing production of weapons of mass destruction and known ties to terrorist organizations, as well as Iraq's continued violations of UN Security Council resolutions, amounted to a threat to the US and the world community.

The Bush administration's overall rationale for the invasion of Iraq was presented in detail by US Secretary of State Colin Powell to the United Nations Security Council on February 5, 2003. In summary, he stated,

“

We know that Saddam Hussein is determined to keep his weapons of mass destruction; he's determined to make more. Given Saddam Hussein's history of aggression... given what we know of his terrorist associations and given his determination to exact revenge on those who oppose him, should we take the risk that he will not some day use these weapons at a time and the place and in the manner of his choosing at a time when the world is in a much weaker position to respond? The United States will not and cannot run that risk to the American people. Leaving Saddam Hussein in possession of weapons of mass destruction for a few more months or years is not an option, not in a post-September 11 world.

”

Since the invasion, the US and British government claims concerning Iraqi weapons programs and links to terrorist organizations have been discredited. While the debate of whether Iraq intended to develop chemical, biological, and nuclear weapons in the future remains open, no WMDs have been found in Iraq since the invasion despite comprehensive inspections lasting more than 18 months. In Cairo, on February 24, 2001, Colin Powell had predicted as much, saying, "Hussein has not developed any significant capability with respect to weapons of mass destruction. He is unable to project conventional power against his neighbours." Similarly, assertions of significant operational links between the Iraqi regime and al Qaeda have largely been discredited by the intelligence community, and Secretary Powell himself eventually admitted he had no incontrovertible proof.

In September 2002, the Bush administration said attempts by Iraq to acquire thousands of high-strength aluminium tubes pointed to a clandestine program to make enriched uranium for nuclear bombs. Powell, in his address to the UN Security Council just before the war, referred to the aluminium tubes. A report released by the Institute for Science and International Security in 2002, however, reported that it was highly unlikely that the tubes could be used to enrich uranium. Powell later admitted he had presented an inaccurate case to the United Nations on Iraqi weapons, based on sourcing that was wrong and in some cases "deliberately misleading."

The Bush administration asserted that the Hussein government had sought to purchase yellowcake uranium from Niger. On March 7, 2003, the US submitted intelligence documents as evidence to the International Atomic Energy Agency. These documents were dismissed by the IAEA as forgeries, with the concurrence in that judgment of outside experts. At the time, a US official claimed that the evidence was submitted to the IAEA without knowledge of its provenance and characterized any mistakes as "more likely due to incompetence not malice".

Unmanned Iraqi drones

In October 2002, a few days before the US Senate vote on the Authorization for Use of Military Force Against Iraq Resolution, about 75 senators were told in closed session that the Iraqi government had the means of delivering biological and chemical weapons of mass destruction by unmanned aerial vehicle (UAV) drones that could be launched from ships off the US' Atlantic coast to attack US eastern seaboard cities. Colin Powell suggested in his presentation to the United Nations that UAVs were transported out of Iraq and could be launched against the US. In fact, Iraq had no offensive UAV fleet or any capability of putting UAVs on ships. Iraq's UAV fleet consisted of less than a handful of outdated Czech training drones. At the time, there was a vigorous dispute within the intelligence community whether the CIA's conclusions about Iraq's UAV fleet were accurate. The US Air Force agency denied outright that Iraq possessed any offensive UAV capability.

Human rights

As evidence supporting U.S. and British claims about Iraqi WMDs and links to terrorism weakened, some claim supporters of the invasion have increasingly shifted their justification to the human rights violations of the Hussein government. Leading human rights groups such as Human Rights Watch have argued, however, that they believe human rights concerns were never a central justification for the invasion, nor do they believe that military intervention was justifiable on humanitarian grounds, most significantly because "the killing in Iraq at the time was not of the exceptional nature that would justify such intervention." Many supporters of the war, however, claim from the start human rights concerns were among the reasons given for the invasion, and that the threat of weapons of mass destruction was emphasized at the United Nations, since this dealt with Iraq flouting UN resolutions. They further claim human rights groups that oppose the war have no objective standard regarding when to invade a country.
