Another reason for the start of the war was that many people thought that Abu Musab al-Zarqawi, one of the leaders of al-Qaeda, was hiding in Iraq after the September 11, 2001 attacks. Though Saddam Hussein was not involved in the planning of the September 11 attacks, many people accused him of giving al-Qaeda a safe place to hide from the United States. The war was extremely controversial. Many British and American people blamed British Prime Minister Tony Blair and the American President, George W. Bush.
