The neocons pondered the question just two days before the Uzbeks publicly kicked American troops out of the Karshi-Khanabad (K2) airbase. Here's a summary of the presentations on the AEI website--note that none of the assembled pundits predicted the dramatic rejection of America's leadership in the Global War on Terror (Uzbekistan controls access to northern Afghanistan) that actually took place. The Karshi-Khanabad air base dispute is not even mentioned in the official AEI summary, a significant omission.
That said, the AEI webcast showcases a fascinating, passionate debate between William Kristol and Fred Starr, an interesting presentation by Chris Seiple that quotes E.H. Carr, and Martha Brill Olcott's attempt to find a middle way--as well as a lively question-and-answer session.
Leon Aron should be congratulated for bringing this panel together.
