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).
Well, Eastern Europe was under the thumb of the Evil Empire, and Western Europe in its shadow. The well springs of American religiousity run much deeper than that.
