Jingoism

Jingoism is a term used to describe extreme patriotism, especially in the form of a warlike foreign policy. The term is often derogatory. The foreign policy of the United States has been described by as jingoist on occasion in history, most recently in criticisms by liberals of how Republican President George W. Bush handled the Iraq War. Liberals have not used to the term to criticize Democratic Presidents' starting of wars, as in the cases of Democratic President Franklin D. Roosevelt (World War II), Democratic President Harry S Truman (Korean War) and Democratic President Lyndon Johnson (Vietnam War).

The term comes from the now outdated and derogatory noun jingo, which describes one who vehemently supports policies that favor war, especially in the name of extreme patriotism.
