United States-led military invasion
The 2003 invasion of Iraq was the first stage of the Iraq War. The invasion began on 20 March 2003 and lasted just over one month, including 26 days of major combat operations, in which a United States-led combined force of troops from the United States, the United Kingdom, Australia and Poland invaded the Republic of Iraq. Twenty-two days after the first day of the invasion, the capital city of Baghdad was captured by coalition forces on 9 April after the six-day-long Battle of Baghdad. This early stage of the war formally ended on 1 May when U.S. President George W. Bush declared the "end of major combat operations" in his Mission Accomplished speech, after which the Coalition Provisional Authority (CPA) was established as the first of several successive transitional governments leading up to the first Iraqi parliamentary election in January 2005. U.S. military forces later remained in Iraq until the withdrawal in 2011.
The coalition sent 160,000 troops into Iraq during the initial invasion phase, which lasted from 19 March to 1 May. About 73% or 130,000 soldiers were American, with about 45,000 British soldiers (25%), 2,000 Australian soldiers (1%), and ~200 Polish JW GROM commandos (0.1%). Thirty-six other countries were involved in its aftermath. In preparation for the invasion, 100,000 U.S. troops assembled in Kuwait by 18 February. The coalition forces also received support from the Peshmerga in Iraqi Kurdistan.
According to U.S. President George W. Bush and UK Prime Minister Tony Blair, the coalition aimed "to disarm Iraq of weapons of mass destruction [WMDs], to end Saddam Hussein's support for terrorism, and to free the Iraqi people", even though the UN inspection team led by Hans Blix had declared it had found no evidence of the existence of WMDs just before the start of the invasion. Others place a much greater emphasis on the impact of the September 11 attacks, on the role this played in changing U.S. strategic calculations, and the rise of the freedom agenda. According to Blair, the trigger was Iraq's failure to take a "final opportunity" to disarm itself of alleged nuclear, chemical, and biological weapons that U.S. and British officials called an immediate and intolerable threat to world peace.
In a January 2003 CBS poll, 64% of Americans had approved of military action against Iraq; however, 63% wanted Bush to find a diplomatic solution rather than go to war, and 62% believed the threat of terrorism directed against the U.S. would increase due to war. The invasion was strongly opposed by some long-standing U.S. allies, including the governments of France, Germany, and New Zealand. Their leaders argued that there was no evidence of weapons of mass destruction in Iraq and that invading that country was not justified in the context of UNMOVIC's 12 February 2003 report. About 5,000 largely unusable chemical warheads, shells or aviation bombs were discovered during the Iraq War, but these had been built and abandoned earlier in Saddam Hussein's rule before the 1991 Gulf War. The discoveries of these chemical weapons did not support the government's invasion rationale. In September 2004, Kofi Annan, United Nations Secretary-General at the time, called the invasion illegal under international law and said it was a breach of the UN Charter.
On 15 February 2003, a month before the invasion, there were worldwide protests against the Iraq War, including a rally of three million people in Rome, which the Guinness World Records listed as the largest-ever anti-war rally. According to the French academic Dominique Reynié, between 3 January and 12 April 2003, 36 million people across the globe took part in almost 3,000 protests against the Iraq war.
The invasion was preceded by an airstrike on the Presidential Palace in Baghdad on 20 March 2003. The following day, coalition forces launched an incursion into Basra Governorate from their massing point close to the Iraqi-Kuwaiti border. While special forces launched an amphibious assault from the Persian Gulf to secure Basra and the surrounding petroleum fields, the main invasion army moved into southern Iraq, occupying the region and engaging in the Battle of Nasiriyah on 23 March. Massive air strikes across the country and against Iraqi command and control threw the defending army into chaos and prevented an effective resistance. On 26 March, the 173rd Airborne Brigade was airdropped near the northern city of Kirkuk, where they joined forces with Kurdish rebels and fought several actions against the Iraqi Army, to secure the northern part of the country.
The main body of coalition forces continued their drive into the heart of Iraq and were met with little resistance. Most of the Iraqi military was quickly defeated and the coalition occupied Baghdad on 9 April. Other operations occurred against pockets of the Iraqi Army, including the capture and occupation of Kirkuk on 10 April, and the attack on and capture of Tikrit on 15 April. Iraqi president Saddam Hussein and the central leadership went into hiding as the coalition forces completed the occupation of the country. On 1 May, President George W. Bush declared an end to major combat operations: this ended the invasion period and began the period of military occupation. Saddam Hussein was captured by U.S. forces on 13 December.
Prelude to the invasion.
Hostilities of the Gulf War were suspended on 28 February 1991, with a cease-fire negotiated between the UN coalition and Iraq. The U.S. and its allies tried to keep Saddam in check with military actions such as Operation Southern Watch, which was conducted by Joint Task Force Southwest Asia (JTF-SWA) with the mission of monitoring and controlling airspace south of the 32nd Parallel (extended to the 33rd Parallel in 1996) as well as using economic sanctions. It was revealed that a biological weapons (BW) program in Iraq had begun in the early 1980s with help from the U.S. and Europe who were unaware of Iraq's intentions, in violation of the Biological Weapons Convention (BWC) of 1972. Details of the BW program—along with a chemical weapons program—surfaced after the Gulf War (1990–91) following investigations conducted by the United Nations Special Commission (UNSCOM) which had been charged with the post-war disarmament of Saddam's Iraq. The investigation concluded that the program had not continued after the war. The U.S. and its allies then maintained a policy of "containment" towards Iraq. This policy involved numerous economic sanctions by the UN Security Council; the enforcement of Iraqi no-fly zones declared by the U.S. and the UK to protect the Kurds in Iraqi Kurdistan and Shias in the south from aerial attacks by the Iraqi government; and ongoing inspections. Iraqi military helicopters and planes regularly contested the no-fly zones.
In October 1998, removing the Iraqi government became official U.S. foreign policy with enactment of the Iraq Liberation Act. Enacted following the expulsion of UN weapons inspectors the preceding August (after some had been accused of spying for the U.S.), the act provided $97 million for Iraqi "democratic opposition organizations" to "establish a program to support a transition to democracy in Iraq." This legislation contrasted with the terms set out in United Nations Security Council Resolution 687, which focused on weapons and weapons programs and made no mention of regime change. One month after the passage of the Iraq Liberation Act, the U.S. and UK launched a bombardment campaign of Iraq called Operation Desert Fox. The campaign's express rationale was to hamper Saddam Hussein's government's ability to produce chemical, biological, and nuclear weapons, but U.S. intelligence personnel also hoped it would help weaken Saddam's grip on power.
With the election of George W. Bush as president in 2000, the U.S. moved towards a more aggressive policy toward Iraq. The Republican Party's campaign platform in the 2000 election called for "full implementation" of the Iraq Liberation Act as "a starting point" in a plan to "remove" Saddam. After leaving the George W. Bush administration, Treasury Secretary Paul O'Neill said that an attack on Iraq had been planned since Bush's inauguration and that the first United States National Security Council meeting involved discussion of an invasion. O'Neill later backtracked, saying that these discussions were part of a continuation of foreign policy first put into place by the Clinton administration.
Despite the Bush administration's stated interest in invading Iraq, little formal movement towards an invasion occurred until the 11 September attacks. For example, the administration prepared Operation Desert Badger to respond aggressively if any Air Force pilot was shot down while flying over Iraq, but this did not happen. Secretary of Defense Donald Rumsfeld dismissed National Security Agency (NSA) intercept data available by midday of the 11th that pointed to al-Qaeda's culpability, and by mid-afternoon ordered the Pentagon to prepare plans for attacking Iraq. According to aides who were with him in the National Military Command Center on that day, Rumsfeld asked for: "best info fast. Judge whether good enough hit Saddam Hussein at same time. Not only Osama bin Laden." A written by Rumsfeld in November 2001 considers an Iraq war. The rationale for invading Iraq as a response to 9/11 has been widely questioned, as there was no cooperation between Saddam Hussein and al-Qaeda.
On 20 September 2001, Bush addressed a joint session of Congress (simulcast live to the world), and announced his new "War on Terror". This announcement was accompanied by the doctrine of "pre-emptive" military action, later termed the Bush Doctrine. Allegations of a connection between Saddam Hussein and al-Qaeda were regularly made by several senior officials in the Bush administration, who asserted that a highly secretive relationship existed between Saddam and the radical Islamist militant organization al-Qaeda from 1992 to 2003, specifically through a series of meetings reportedly involving the Iraqi Intelligence Service (IIS). Some Bush advisers favored an immediate invasion of Iraq, while others advocated building an international coalition and obtaining United Nations authorization. Bush eventually decided to seek UN authorization, while still reserving the option of invading without it.
General David Petraeus recalled in an interview his experience during the time before the invasion, stating that "When we were getting ready for what became the invasion of Iraq, the prevailing wisdom was that we were going to have a long, hard fight to Baghdad, and it was really going to be hard to take Baghdad. The road to deployment, which was a very compressed road for the 101st Airborne Division, started with a seminar on military operations in urban terrain, because that was viewed as the decisive event in the takedown of the regime in Iraq — that and finding and destroying the weapons of mass destruction."
Preparations for war.
While there had been some earlier talk of action against Iraq, the Bush administration waited until September 2002 to call for action, with White House Chief of Staff Andrew Card saying, "From a marketing point of view, you don't introduce new products in August." Bush began formally making his case to the international community for an invasion of Iraq in his 12 September 2002 address to the United Nations General Assembly. Benjamin Netanyahu testified before US Congress on September 12, 2002 with an expert testimony, encouraging America to invade Iraq and stating that there is "no question" that Saddam is working on WMDs.
The United Kingdom agreed with the U.S. actions, while France and Germany were critical of plans to invade Iraq, arguing instead for continued diplomacy and weapons inspections. After considerable debate, the UN Security Council adopted a compromise resolution, UN Security Council Resolution 1441, which authorized the resumption of weapons inspections and promised "serious consequences" for non-compliance. Security Council members France and Russia made clear that they did not consider these consequences to include the use of force to overthrow the Iraqi government. Both the U.S. ambassador to the UN, John Negroponte, and the UK ambassador, Jeremy Greenstock, publicly confirmed this reading of the resolution, assuring that Resolution 1441 provided no "automaticity" or "hidden triggers" for an invasion without further consultation of the Security Council.
Resolution 1441 gave Iraq "a final opportunity to comply with its disarmament obligations" and set up inspections by the United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) and the International Atomic Energy Agency (IAEA). Saddam accepted the resolution on 13 November and inspectors returned to Iraq under the direction of UNMOVIC chairman Hans Blix and IAEA Director-General Mohamed ElBaradei. As of February 2003, the IAEA "found no evidence or plausible indication of the revival of a nuclear weapons program
