Operation Iraqi Freedom

The Iraq War was a protracted armed conflict in Iraq from 2003 to 2011. It began with the invasion of Iraq by the United States-led coalition that overthrew the Ba'athist government of Saddam Hussein. The conflict continued for much of the next decade as an insurgency emerged to oppose the coalition forces and the post-invasion Iraqi government. US troops were officially withdrawn in 2011. The United States became re-involved in 2014 at the head of a new coalition, and the insurgency and many dimensions of the armed conflict are ongoing. The invasion occurred as part of the George W. Bush administration's war on terror following the September 11 attacks. In October 2002, the United States Congress passed a joint resolution which granted Bush the power to use military force against the Iraqi government. The Iraq War officially began on 20 March 2003, when the US, joined by the United Kingdom, Australia, and Poland, launched a "shock and awe" bombing campaign. Shortly following the bombing campaign, US-led forces launched a ground invasion of Iraq. Iraqi forces were quickly overwhelmed as coalition forces swept through the country. The invasion led to the collapse of the Ba'athist government; Saddam Hussein was captured during Operation Red Dawn in December of that same year and executed three years later. The power vacuum following Saddam's demise, and mismanagement by the Coalition Provisional Authority, led to widespread civil war between Shias and Sunnis, as well as a lengthy insurgency against coalition forces. The United States responded with a build-up of 170,000 troops in 2007. This build-up gave greater control to Iraq's government and military while also giving the United States a greater say in the postwar reconstruction of Iraq. In 2008, President Bush agreed to a withdrawal of all US combat troops from Iraq. The withdrawal was completed under Barack Obama in December 2011. The United States based most of its rationale for the invasion on claims that Iraq had a weapons of mass destruction (WMD) program and posed a threat to the United States and its allies. Additionally, some US officials accused Saddam of harbouring and supporting al-Qaeda. However, in 2004 the 9/11 Commission concluded there was no evidence of any relationship between Saddam's regime and al-Qaeda. No stockpiles of WMDs or active WMD program were ever found in Iraq.
