Past U.S. presidents Franklin D. Roosevelt, Harry S. Truman, John F. Kennedy and Lyndon B. Johnson have been described as liberal hawks for their roles in bringing about the US's status as the world's premier military power. The Clinton Doctrine can also be considered as consistent with this vision. Today the term is most frequently used to describe liberals and leftists who supported or still support the decision to invade Iraq in 2003, which was authorized by the United States Congress and ordered by president George W. Bush. The war has stirred heated controversy among all political sides of the debate. The American left was divided over the issue of whether going to war in Iraq was the right decision, as some liberals felt that they should support the war, in accordance with the philosophy of liberal internationalism, which had caused them to support military intervention in the past.
