The Bush administration faced three major strategic choices between September 11 and October 7, when the military campaign started: how to define the war, what to do about the Taliban, and what kind of military footprint to deploy. The administration chose to frame the conflict as a War on Terror, to treat the Taliban as of secondary importance, and to adopt a light footprint. The first choice – to declare a War on Terror – has been the subject of ample and justified criticism, then and now. The latter two choices made more sense at the time, and the Taliban’s fall from power two months later, on December 7, seemed to vindicate the administration’s impressive improvisation. But the sense of vindication also numbed the administration to the need to adapt as circumstances changed.
