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."

{{Further, 2007 in Iraq, Iraq War troop surge of 2007, Timeline of the Iraq War troop surge of 2007, Strategic reset= Planned troop reduction
= In a speech made to Congress on 10 September 2007, David Petraeus, 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. These Guardian militias are intended to support and secure various Sunni neighborhoods against the Islamists.= Tensions with Iran

In the fall of 2007, the Turkish military stated their right to cross the Iraqi Kurdistan border in "hot pursuit" of PKK militants and began shelling Kurdish areas in Iraq and attacking PKK bases in the Mount Cudi region with aircraft. 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.

{{Further, 2008 in Iraq, Iraqi Civil War (2006–2008) Throughout 2008, US officials and independent think tanks began to point to improvements in the security situation, as measured by key statistics. According to the US Defense Department, in December 2008 the "overall level of violence" in the country had dropped 80% since before Iraq War troop surge of 2007, the surge began in January 2007, and the country's murder rate had dropped to prewar levels.

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.

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.

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
