US-Led Coalition Invades Iraq
Tensions had escalated after the September 11 attacks as the United States accused Iraq under Saddam Hussein of possessing weapons of mass destruction and supporting terrorism. A coalition including the UK, Australia, and Poland prepared military action despite lacking full UN Security Council approval. On March 20, 2003, coalition forces launched airstrikes and a ground invasion from Kuwait, rapidly advancing toward Baghdad. Iraqi resistance varied, but major cities fell within weeks. The operation, codenamed Iraqi Freedom, marked the start of a prolonged conflict that toppled the Ba'athist regime.
