I t’s been two decades since, on March 19, 2003, United States forces invaded Iraq. President George W. Bush ordered the invasion to neutralize what he said was the threat of weapons of mass destruction posed by Iraqi dictator Saddam Hussein. Except it turned out Saddam did not have weapons of mass destruction. U.S. forces searched and searched and searched, and never found them. In all, 4,586 American servicemen and women died in the war, and 32,455 were wounded.
