{{Further, Criticism of the Iraq War, Legitimacy of the 2003 invasion of Iraq, Legality of the Iraq War, Protests against the Iraq War In October 2002, former US President Bill Clinton warned about possible dangers of pre-emptive military action against Iraq. Speaking in the UK at a Labour Party (UK), Labour Party conference he said: "As a preemptive action today, however well-justified, may come back with unwelcome consequences in the future.... I don't care how precise your bombs and your weapons are when you set them off, innocent people will die." Of 209 House Democratic Party (United States), Democrats in Congress, 126 voted against the Iraq Resolution, Authorization for Use of Military Force Against Iraq Resolution of 2002, although 29 of 50 Democrats in the Senate voted in favor of it. Only one Republican Senator, Lincoln Chafee, voted against it. The Senate's lone Independent, Jim Jeffords, voted against it. Retired US Marine, former Navy Secretary and future US senator Jim Webb wrote shortly before the vote, "Those who are pushing for a unilateral war in Iraq know full well that there is no exit strategy if we invade." In the same period, Pope John Paul II publicly condemned the military intervention. During a private meeting, he also said directly to George W. Bush: "Mr. President, you know my opinion about the war in Iraq. Let's talk about something else. Every violence, against one or a million, is a blasphemy addressed to the image and likeness of God."History

The Iraq Study Group made up of people from both of the major US parties, was led by co-chairs James Baker, a former Secretary of State (Republican), and Lee H. Hamilton, a former US Representative (Democrat). It concluded that "the situation in Iraq is grave and deteriorating" and "US forces seem to be caught in a mission that has no foreseeable end."

= In a speech made to Congress on 10 September 2007, Petraeus "envisioned the withdrawal of roughly 30,000 US troops by next summer, beginning with a Marine contingent [in September]." On 13 September, Bush backed a limited withdrawal of troops from Iraq. Bush said 5,700 personnel would be home by Christmas 2007, and expected thousands more to return by July 2008. The plan would take troop numbers back to their level before the surge at the beginning of 2007.= Effects of the surge on security
= By March 2008, violence in Iraq was reported curtailed by 40–80%, according to a Pentagon report. Independent reports raised questions about those assessments. An Iraqi military spokesman claimed that civilian deaths since the start of the troop surge plan were 265 in Baghdad, down from 1,440 in the four previous weeks. ''The New York Times'' counted more than 450 Iraqi civilians killed during the same 28‑day period, based on initial daily reports from Iraqi Interior Ministry and hospital officials.= Political developments
= More than half of the members of Iraq's parliament rejected the continuing occupation of their country for the first time. 144 of the 275 lawmakers signed onto a legislative petition that would require the Iraqi government to seek approval from Parliament before it requests an extension of the UN mandate for foreign forces to be in Iraq, which expires at the end of 2008. It also calls for a timetable for troop withdrawal and a freeze on the size of foreign forces. The UN Security Council mandate for US‑led forces in Iraq will terminate "if requested by the government of Iraq." 59% of those polled in the US support a timetable for withdrawal. In mid-2007, the Coalition began a controversial program to recruit Iraqi Sunnis (often former insurgents) for the formation of "Guardian" militias.

The Turkish parliament approved a resolution permitting the military to pursue the PKK in Iraqi Kurdistan. In November, Turkish gunships attacked parts of northern Iraq in the first such attack by Turkish aircraft since the border tensions escalated. Another series of attacks in mid-December hit PKK targets in the Qandil, Zap, Avashin and Hakurk regions. The latest series of attacks involved at least 50 aircraft and artillery and Kurdish officials reported one civilian killed and two wounded.

On 15 January 2011, three US troops were killed in Iraq. One of the troops was killed on a military operation in central Iraq, while the other two troops were deliberately shot by one or two Iraqi soldiers during a training exercise. On 6 June, five US troops were killed in an apparent rocket attack on JSS Loyalty. A sixth soldier, who was wounded in the attack, died 10 days later of his wounds. On 13 June 2011, two US troops were killed in an IED attack located in Wasit Governorate. On 26 June 2011, a US soldier was killed. Sergeant Brent McBride was sentenced to four years, two months for his involvement in the death. On 29 June, three US troops were killed in a rocket attack on a US base located near the border with Iran. It was speculated that the militant group responsible for the attack was the same one which attacked JSS Loyalty just over three weeks before. With the three deaths, June 2011, became the bloodiest month in Iraq for the US military since June 2009, with 15 US soldiers killed, only one of them outside combat. On 7 July, two US troops were killed and one seriously injured in an IED attack at Victory Base Complex outside Baghdad. They were members of the 145th Brigade Support Battalion, 116th Cavalry Heavy Brigade Combat Team, an Idaho Army National Guard unit base in Post Falls, Idaho. Spc. Nathan R. Beyers, 24, and Spc. Nicholas W. Newby, 20, were killed in the attack, Staff Sgt. Jazon Rzepa, 30, was seriously injured. In September, Iraq signed a contract to buy 18 Lockheed Martin F-16 warplanes, becoming the 26th nation to operate the F-16. Because of windfall profits from oil, the Iraqi government is planning to double this originally planned 18, to 36 F-16s. Iraq is relying on the US military for air support as it rebuilds its forces and battles a stubborn Islamist insurgency. With the collapse of the discussions about extending the stay of any US troops beyond 2011, where they would not be granted any immunity from the Iraqi government, on 21 October 2011, President Obama announced at a White House press conference that all remaining US troops and trainers would leave Iraq by the end of the year as previously scheduled, bringing the US mission in Iraq to an end.{{cite news , title=Barack Obama: All U.S. troops to leave Iraq in 2011, url=https://www.bbc.co.uk/news/world-us-canada-15410154, work=BBC News, access-date=21 October 2011, date=21 October 2011 The last American soldier to die in Iraq before the withdrawal, SPC.

In March 2013, the total cost of the Iraq War to date was estimated at $1.7 trillion by the Watson Institute of International Studies at Brown University. Some argue that the total cost of the war to the US economy will range from $3 trillion to {{Nowrap, $6 trillion, including interest rates, by 2053, as described in the Watson Institute's report. The upper ranges of these estimates include long-term veterans costs and economic impacts. For example, Harvard's public finance expert Linda J. Bilmes has estimated that the long-term cost of providing disability compensation and medical care to US troops injured in the Iraq conflict will reach nearly $1 trillion over the next 40 years, and that the war in Iraq diverted resources from the war in Afghanistan, led to rising oil prices, increased the federal debt, and contributed to a global financial crisis. A CNN report noted that the United States–led interim government, the Coalition Provisional Authority lasting until 2004 in Iraq had lost $8.8 billion in the Development Fund for Iraq. In June 2011, it was reported by CBS News that $6 billion in neatly packaged blocks of $100 bills was air-lifted into Iraq by the George W. Bush administration, which flew it into Baghdad aboard C‑130 military cargo planes. In total, the ''Times'' says $12 billion in cash was flown into Iraq in 21 separate flights by May 2004, all of which has disappeared. An inspector general's report mentioned that "'Severe inefficiencies and poor management' by the Coalition Provisional Authority would leave no guarantee that the money was properly used", said Stuart W. Bowen, Jr., director of the Office of the Special Inspector General for Iraq Reconstruction. "The CPA did not establish or implement sufficient managerial, financial, and contractual controls to ensure that funds were used in a transparent manner." Bowen told the Times the missing money may represent "the largest theft of funds in national history."Reparations

Relation to the Global War on Terrorism
{{Main, Iraq War and the War on Terror {{Further, Criticism of the War on Terrorism, Saddam Hussein and al-Qaeda, Saddam Hussein and al-Qaeda timeline Though explicitly stating that Iraq had "nothing" to do with 9/11, erstwhile President George W. Bush consistently referred to the Iraq War as "the central front in the War on Terrorism, War on Terror", and argued that if the United States pulled out of Iraq, "terrorists will follow us here". While other proponents of the war regularly echoed this assertion, as the conflict dragged on, members of the US Congress, the US public, and even US troops questioned the connection between Iraq and the fight against anti-US terrorism. In particular, a consensus developed among intelligence experts that the Iraq War actually increased terrorism. Counterterrorism expert Rohan Gunaratna frequently referred to the invasion of Iraq as a "fatal mistake". London's International Institute for Strategic Studies concluded in 2004 that the occupation of Iraq had become "a potent global recruitment pretext" for Mujahideen and that the invasion "galvanised" al-Qaeda and "perversely inspired insurgent violence" there. The US National Intelligence Council concluded in a January 2005 report that the war in Iraq had become a breeding ground for a new generation of terrorists; David Low, the national intelligence officer for transnational threats, indicated that the report concluded that the war in Iraq provided terrorists with "a training ground, a recruitment ground, the opportunity for enhancing technical skills ... There is even, under the best scenario, over time, the likelihood that some of the jihadists who are not killed there will, in a sense, go home, wherever home is, and will, therefore, disperse to various other countries." The council's chairman Robert Hutchings said, "At the moment, Iraq is a magnet for international terrorist activity." And the 2006 National Intelligence Estimate, which outlined the considered judgment of all 16 US intelligence agencies, held that "The Iraq conflict has become the 'cause célèbre' for jihadists, breeding a deep resentment of US involvement in the Muslim world and cultivating supporters for the global jihadist movement."Foreign involvement
