In the aftermath of the September 11 attacks, U.S. president George W. Bush included Saddam in his "Axis of evil". In 2002 the UN Security Council adopted Resolution 1441, which stated that Iraq had failed to fulfill its obligations demanded by the UN. The United States and the United Kingdom would use Resolution 1441 as a pretext for war. The 2003 US-led invasion of the country forced the Ba'ath Party and Saddam to go underground. Saddam was captured later that year, and was executed in 2006.
