10. The Decision to Invade Iraq in 2003
President George W. Bush’s decision to invade Iraq in 2003 remains one of the most contentious actions in recent U.S. history. Justified by claims of weapons of mass destruction and links to terrorism, the invasion aimed to topple Saddam Hussein’s regime. However, the absence of such weapons and the ensuing instability sparked intense criticism and debate over U.S. foreign policy. The invasion had profound long-term consequences, including prolonged military engagement, regional instability, and significant loss of life. It also shaped public opinion and policy discussions on military intervention and its implications for global security.
