The U.S. war with Iraq that resulted in the removal of Saddam Hussein will be remembered as one of the most momentous events of the early 21st century and one of the most contentious. Much has been written about the decision to invade and the difficulties the United States and its allies encountered during and after the 2003 invasion and the resulting occupation. As time passes, however, the focus of analysis will naturally shift toward the war s longer-term impact on U.S. foreign policy. The lasting effect that the Iraq war has had on U.S. security structures and institutions is one important dimension. This paper presents an admittedly early overview of the major ways in which the war has and has not shaped U.S. security and foreign policy structures and the implications for the future. It is intended for readers who have a general understanding of the war and of the basic apparatus of U.S. foreign and security policy. Necessarily preliminary, it is intended as an initial contribution to the discussion rather than a definitive review of the subject.
