The Iraq War, or the War in Iraq (also referred to as the Occupation of Iraq, the Second Gulf War, or Operation Iraqi Freedom by the United States military), was a conflict that occurred in Iraq from March 20, 2003^[41][42] to December 15, 2011,^[43] though sectarian violence continues since and has caused hundreds of fatalities.

Prior to the war, the governments of the United States and the United Kingdom claimed that Iraq's alleged possession of weapons of mass destruction (WMD) posed a threat to their security and that of their coalition/regional allies.^[44][45][46] In 2002, the United Nations Security Council passed Resolution 1441 which called for Iraq to completely cooperate with UN weapon inspectors to verify that Iraq was not in possession of WMD and cruise missiles. The United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) found no evidence of WMD, but could not verify the accuracy of Iraq's declarations regarding what weapons it possessed.^{[47][48][49][50]} Lead weapons inspector Hans Blix advised the UN Security Council that while Iraq was cooperating in terms of access, Iraq's declarations with regards to WMD still could not be verified.^[47][51]

After investigation following the invasion, the U.S.-led Iraq Survey Group concluded that Iraq had ended its nuclear, chemical, and biological programs in 1991 and had no active programs at the time of the invasion, but that they intended to resume production if the Iraq sanctions were lifted.^[52] Although some degraded remnants of misplaced or abandoned chemical weapons from before 1991 were found, they were not the weapons which had been the one of the main arguments for the invasion.^[53]

Some US officials also accused Iraqi President Saddam Hussein of harboring and supporting al-Qaeda,^[54] but no evidence of a meaningful connection was ever found.^[55][56] Other proclaimed reasons for the invasion included Iraq's financial support for the families of Palestinian suicide bombers,^[57] Iraqi government human rights abuses,^[58] and an effort to spread democracy to the country.^[59][60]

The invasion of Iraq led to an occupation and the eventual capture of President Hussein, who was later tried in an Iraqi court of law and executed by the new Iraqi government. Violence against coalition forces and among various sectarian groups soon led to the Iraqi insurgency, strife between many Sunni and Shia Iraqi groups, and the emergence of a new faction of Al-Qaeda in Iraq.^[61][62]

In June 2008, U.S. Department of Defense officials claimed security and economic indicators began to show signs of improvement in what they hailed as significant and fragile gains.^[63] Iraq was fifth on the 2008 Failed States Index,^[64] and sixth on the 2009 list.^[65] As public opinion favoring troop withdrawals increased and as Iraqi forces began to take responsibility for security, member nations of the Coalition withdrew their forces.^[66][67] In late 2008, the U.S. and Iraqi governments approved a Status of Forces Agreement effective through January 1, 2012.^[68] The Iraqi Parliament also ratified a Strategic Framework Agreement with the U.S.,^[69] aimed at ensuring cooperation in constitutional rights, threat deterrence, education,^[70] energy development, and other areas.^[71]

In late February 2009, newly elected U.S. President Barack Obama announced an 18-month withdrawal window for combat forces, with approximately 50,000 troops remaining in the country "to advise and train Iraqi security forces and to provide intelligence and surveillance".^[72][73] General Ray Odierno, the top U.S. military commander in Iraq, said he believes all U.S. troops will be out of the country by the end of 2011,^[74] while UK forces ended combat operations on April 30, 2009.^[75] Iraqi Prime Minister Nouri al-Maliki has said he supports the accelerated pullout of U.S. forces.^[76] In a speech at the Oval Office on 31 August 2010 Obama declared "the American combat mission in Iraq has ended. Operation Iraqi Freedom is over, and the Iraqi people now have lead responsibility for the security of their country."^[77][78][79] Beginning September 1, 2010, the American operational name for its involvement in Iraq changed from "Operation Iraqi Freedom" to "Operation New Dawn." The remaining 50,000 U.S. troops were designated as "advise and assist brigades" assigned to non-combat operations while retaining the ability to revert to combat operations as necessary. Two combat aviation brigades also remain in Iraq.^[80] In September 2010, the Associated Press issued an internal memo reminding its reporters that "combat in Iraq is not over," and "U.S. troops remain involved in combat operations alongside Iraqi forces, although U.S. officials say the American combat mission has formally ended."^[81][82]

On October 21, 2011, President Obama announced that all U.S. troops and trainers would leave Iraq by the end of the year, bringing the U.S. mission in Iraq to an end.^[83] On December 15, 2011, U.S. Defense Secretary Leon Panetta officially declared the Iraq War over, at a flag lowering ceremony in Baghdad.^[84] The last U.S. troops left Iraqi territory on December 18, 2011 at 4:27 UTC.^[85]

Background[link]

Iraq disarmament crisis and pre-war intelligence[link]

UN weapons inspections resume[link]

The issue of Iraq's disarmament reached a crisis in 2002–2003, when Bush demanded a complete end to alleged Iraqi production of weapons of mass destruction and full compliance with UN Security Council Resolutions requiring UN weapons inspectors unfettered access to suspected weapons production facilities. The UN had prohibited Iraq from developing or possessing such weapons after the Gulf War and required Iraq to permit inspections confirming compliance. During inspections in 1999, Iraq alleged that UN inspectors included U.S. intelligence agents that supplied the U.S. with a direct feed of conversations between Iraqi security agencies as well as other information. This was confirmed by the New York Times and the Wall Street Journal.^[86]

During 2002, Bush repeatedly warned of military action unless inspections were allowed to progress unfettered. In accordance with UN Security Council Resolution 1441 Iraq reluctantly agreed to new inspections in late 2002. A third weapons inspection team in 2003 led by David Kelly (weapons expert) viewed and photographed with the cooperation of Iraqis two alleged mobile weapons laboratories which were facilities for the production of hydrogen gas to fill balloons.

Shortly before the invasion Hans Blix, the lead weapons inspector, advised the UN Security Council that Iraq was cooperating with inspections and that the confirmation of disarmament through inspections could be achieved in a short period of time if Iraq remained cooperative.^[51]

Alleged weapons of mass destruction[link]

Yellowcake uranium[link]

A UN weapons inspector in Iraq

Before the Gulf War, in 1990, Iraq had stockpiled 550 short tons (500 t) of yellowcake uranium at the Tuwaitha nuclear complex about 20 kilometres (12 mi) south of Baghdad.^[87] In late February 2002, the CIA sent former Ambassador Joseph Wilson to investigate reports (later found to be forgeries) that Iraq was attempting to purchase additional yellowcake from Niger. Wilson returned and informed the CIA that reports of yellowcake sales to Iraq were "unequivocally wrong." The Bush administration, however, continued to allege Iraq's attempts to obtain additional yellowcake were a justification for military action, most prominently in the January 2003, State of the Union address, in which President Bush declared that Iraq had sought uranium, citing British intelligence sources.^[88]

2003 State of the Union Address given by President George W. Bush

In response, Wilson wrote a critical New York Times op-ed piece in June 2003 stating that he had personally investigated claims of yellowcake purchases and believed them to be fraudulent.^[89] After Wilson's op-ed, Wilson's wife Valerie Plame was publicly identified as an undercover CIA analyst by a columnist. This led to a Justice Department investigation into the source of the leak.

On May 1, 2005, the "Downing Street memo" was published in The Sunday Times. It contained an overview of a secret July 23, 2002, meeting among British government, Ministry of Defence, and British intelligence figures who discussed the build-up to the Iraq war—including direct references to classified U.S. policy of the time. The memo stated, "Bush wanted to remove Saddam, through military action, justified by the conjunction of terrorism and WMD. But the intelligence and facts were being fixed around the policy."^[90]

In September 2002, the Bush administration, the CIA and the DIA said attempts by Iraq to acquire high-strength aluminum tubes that were prohibited under the UN monitoring program and which they said pointed to a clandestine effort to make centrifuges to enrich uranium for nuclear bombs.^[91] This analysis was opposed by the United States Department of Energy (DOE) and INR, which was significant because of DOE's expertise in such gas centrifuges and nuclear weapons programs. The DOE and INR argued that the Iraqi tubes were poorly suited for centrifuges and that while it was technically possible with additional modification, conventional military uses were more plausible.^[92] A report released by the Institute for Science and International Security in 2002 reported that it was highly unlikely that the tubes could be used to enrich uranium.^[93]

An effort by the DOE to correct this detail in comments prepared for United States Secretary of State Colin Powell's UN appearance was rebuffed by the administration^[93][94] and Powell, in his address to the UN Security Council just before the war, referenced the aluminum tubes, stating that while experts disagreed on whether or not the tubes were destined for a centrifuge program, the specifications of the tubes were unusually tight.^[95] Powell later admitted he had presented what turned out to be an inaccurate case to the UN on Iraqi weapons, and the intelligence he was relying on was, in some cases, "deliberately misleading."^[96][97][98] After the United States presidential election, 2008, and the election of Democratic party nominee Barack Obama, president Bush stated that "[my] biggest regret of all the presidency has to have been the intelligence failure in Iraq".^[99]
