This is a link to the presentation I gave to a plenary panel “The Clash of Cultures and American Hegemony” (this wasn’t my title) at the American Political Science Association annual meeting in Philadelphia on Sept. 1.  Sam Huntington was supposed to be on the panel but was not able to participate; other panelists were Ben Barber (Univ. of Maryland), Steve Walt (Harvard), and Jim Kurth (Swarthmore).
