Liberal hawks refer to past US presidents who took part in bringing about the US's status as the premier military power and liberals and leftists who supported the US invasion of Iraq in 2003 which began on March 19.
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. 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 invasion phase began on 19 March 2003 (air) and 20 March 2003 (ground) and lasted just over one month, including 26 days of major combat operations, in which a combined force of troops from the United States, the United Kingdom, Australia and Poland invaded Iraq.
