Did 11 September 2001 change everything about the United States including its foreign policy? Have the subsequent US-led wars in Afghanistan and Iraq altered the scholarly calculus of what should be studied and how? Must authors determined to assert the continuing importance of history, geopolitics or domestic factors as explanatory variables recast or abandon their existing conclusions to highlight the newer realities after the terrorist attacks and their aftermath? If so, how? These questions lead to others. Is there a usable American past that helps illuminate the dilemmas of the present? If so, where is it found? Is there a sustainable future role for the US in the world, beyond ideology or improvisation? If so, what are its contours? Is the Bush administration truly ‘radical’ or even ‘revolutionary’ in its imperial thrusts? After Afghanistan and Iraq, is American foreign policy still largely a success story? Or is the United States en route to becoming an ordinary country, albeit one with extraordinary resources in both hard and soft power?
