The Iraq War at Ten

April marked the tenth anniversary of the overthrow of Saddam Hussein by the United States and its partners. At this juncture, it is reasonable for Americans—and Iraqis and others—to ask whether the past decade of U.S. involvement in Iraq was worth it. Did the large human and financial costs pro-duce an outcome that justifies the sacrifice? The frustrating reality is that it is still too early to form a definitive answer to this question. It is possible, however, to provide a partial evaluation at this time, one that identifies the relevant variables that should go into such a calculation and provides an assessment of them where possible.
