2003 invasion of Iraq was a major military operation launched by a United States-led coalition to overthrow the government of Ba'athist Iraq under President Saddam Hussein. The invasion, which began on 20 March 2003, involved forces primarily from the United States, the United Kingdom, Australia, and Poland, and concluded with the fall of Baghdad and the collapse of Hussein's regime by early May. The stated justifications for the war, presented by the George W. Bush administration and the Tony Blair government, centered on Iraq's alleged possession of weapons of mass destruction and links to al-Qaeda, claims which were later widely disputed. The rapid conventional victory was followed by a prolonged and violent occupation and insurgency that fundamentally reshaped the Middle East.

Background and causes

The primary public casus belli was the assertion by the United States intelligence community and the British government, particularly detailed in the September Dossier, that Saddam Hussein's regime possessed and was actively developing weapons of mass destruction in violation of United Nations Security Council Resolution 1441. Key figures like Colin Powell presented evidence to the United Nations Security Council, while officials such as Dick Cheney and Donald Rumsfeld emphasized the threat. The broader geopolitical context included the War on Terror following the September 11 attacks, with alleged ties between Ba'athist Iraq and al-Qaeda cited, though these links were tenuous. Diplomatic efforts, led by nations like France, Germany, and Russia on the UN Security Council, failed to authorize force, leading the Coalition of the willing to act without a second UN resolution.

Invasion and major combat operations

Codenamed Operation Iraqi Freedom, the invasion commenced on 20 March 2003 with a "shock and awe" bombing campaign against targets in Baghdad and a ground assault on the port of Umm Qasr. Major coalition ground forces, including the U.S. Army's 3rd Infantry Division and the 1st Marine Division, thrust north from Kuwait towards the capital. Key early battles included the Battle of Nasiriyah, the Battle of Basra led by the British Army's 1st Armoured Division, and the Battle of Karbala. The Battle of Baghdad culminated in the symbolic toppling of a statue of Saddam Hussein in Firdos Square on 9 April. Major combat operations were declared over by President George W. Bush aboard the USS Abraham Lincoln on 1 May 2003, following the Battle of Tikrit.

Post-invasion stabilization and insurgency

The immediate aftermath was marked by widespread looting and the collapse of civil administration, as the Coalition Provisional Authority under L. Paul Bremer disbanded the Iraqi Army and pursued De-Ba'athification. This power vacuum and growing resentment fueled a complex insurgency involving former Ba'ath Party loyalists, Sunni tribes, and foreign jihadists, notably Abu Musab al-Zarqawi's group, which later evolved into al-Qaeda in Iraq. Major battles of this phase included the First Battle of Fallujah and the Second Battle of Fallujah. The insurgency escalated into a sectarian civil war between Sunni and Shia militias, such as the Mahdi Army led by Muqtada al-Sadr.

Aftermath and legacy

The invasion had profound and lasting consequences. No stockpiles of weapons of mass destruction were ever found, leading to intense scrutiny of pre-war intelligence and investigations like the Iraq Inquiry in the United Kingdom. The war resulted in significant loss of life, with estimates of hundreds of thousands of Iraqi civilian casualties and thousands of coalition soldiers killed. Politically, it led to the Execution of Saddam Hussein in 2006 and the eventual establishment of a Shia-led government, altering the regional balance of power in favor of Iran. The conflict severely damaged the credibility of the United States and its allies, influenced the 2008 United States presidential election, and is widely considered a catalyst for the rise of the Islamic State of Iraq and the Levant.
