•The US stated in the run-up to the war of Iraq that Saddam Hussein was developing weapons of mass destruction and so posed a threat to his neighbors and the international community. The Bush administration attempted to establish a case for invading Iraq throughout late 2001, 2002, and early 2003, culminating in Secretary of State Colin Powell's February 2003 statement to the Security Council. After the 2003 invasion of Iraq, intelligence agencies mainly discounted data relating to Iraqi weapons and suspected ties to al-Qaeda. The Bush and Blair administrations moved their focus to secondary reasons for the conflict, such as the regime of Saddam Hussein's human rights record and the promotion of democracy in Iraq. According to polls, almost everyone in the world opposes a war without a UN mandate, and the United States is considered as a threat to international peace.
•Congress gave President Bush the authority to determine whether or not to initiate a military attack in Iraq in October 2002. The Iraq War began on March 20, 2003, when the United States, along with the United Kingdom, Australia, and Poland, launched a "shock and awe" bombing campaign against Iraq. Saddam Hussein was arrested in December 2003 and executed three years later after the invasion brought down the Ba'athist administration.
•After fifteen years of US military involvement in Iraq, public opinion on whether or not it was the right decision to deploy force has become more divided. In March 2018, 48 percent of Americans questioned said the invasion was a bad judgment, while 43 percent said it was a good decision, up 4% from 2014.
