Iraq War

The Iraq War (Arabic: حرب العراق, romanized: ḥarb al-ʿirāq), also referred to as the Second Gulf War, was a protracted armed conflict in Iraq from 2003 to 2011. It began with the invasion by a United States–led coalition, which resulted in the overthrow of the Ba'athist government of Saddam Hussein. During the US occupation of Iraq, the conflict persisted as an insurgency that arose against coalition forces and the newly established Iraqi government. US forces were officially withdrawn in 2011. In 2014, the US became re-engaged in Iraq, leading a new coalition under Combined Joint Task Force – Operation Inherent Resolve, as the conflict evolved into the ongoing Islamic State insurgency. The Iraq invasion was part of the Bush administration's broader war on terror, launched in response to the September 11 attacks. In October 2002, the US Congress passed a bipartisan resolution granting Bush authority to use military force against Iraq. The war began on March 20, 2003, when the US, joined by the UK, Australia, and Poland, initiated a "shock and awe" bombing campaign. Coalition forces launched a ground invasion, defeating Iraqi forces and toppling the Ba'athist regime. Saddam Hussein was captured in 2003 and executed in 2006. The fall of Saddam's regime created a power vacuum, which, along with the Coalition Provisional Authority's mismanagement, fueled a sectarian civil war between Iraq's Shia majority and Sunni minority, and contributed to a lengthy insurgency. In response, the US deployed an additional 170,000 troops during the 2007 troop surge, which helped stabilize parts of the country. In 2008, Bush agreed to withdraw US combat troops, a process completed in 2011 under President Barack Obama. The primary rationale for the invasion centered around false claims that Iraq possessed weapons of mass destruction (WMDs) and that Saddam Hussein was supporting al-Qaeda. The 9/11 Commission concluded in 2004 that there was no credible evidence linking Saddam to al-Qaeda, and no WMD stockpiles were found in Iraq. These false claims faced widespread criticism, in the US and abroad. Kofi Annan, then secretary-general of the United Nations, declared the invasion illegal under international law, as it violated the UN Charter. The 2016 Chilcot Report, a British inquiry, concluded the war was unnecessary, as peaceful alternatives had not been fully explored. Iraq held multi-party elections in 2005, and Nouri al-Maliki became Prime Minister in 2006, a position he held until 2014. His government's policies alienated Iraq's Sunni minority, exacerbating sectarian tensions. The war led to an estimated 150,000 to over a million deaths, including over 100,000 civilians, with most occurring during the post-invasion insurgency and civil war. The war had lasting geopolitical effects, including the emergence of the extremist Islamic State, whose rise led to the 2013–17 War in Iraq. The war damaged the US' international reputation, and Bush's popularity declined. UK prime minister Tony Blair's support for the war diminished his standing, contributing to his resignation in 2007. Among the international law justifications for the Iraq War offered by the United States were the inherent right of anticipatory self-defense and prior authorization by the Security Council.
