I doubt it. That is much too narrow a view. I don't think Islam has anything to do with it. Islam was not on the radar screen until 9-11, and the evil empire went out 10 years before. There was no sign of flagging religious faith in the 1990's. Religion is so much more personal, and micro, than some reaction to macro international events.
Yes, but generational shifts require generations to operate and 10 years does not make a generation, much less the several required for such macro transitions. The conservatism of contemporary Islam itself represents a modern phenomenon of reaction to Western imperialism.
Moreover, I did not mean to suggest that no other factors were operant, just that this was a significant distinction with those other societies that you are presumably drawing a contrast against (Europe & East Asia).
