Not only is the nature of the islamofascist threat more apparent, but it also becomes obvious that many of our supposed 9/11 "allies" or "sympathizers" (such as France, Russia, and Germany) are in fact pro-terrorist, and have been trying to play both sides, taking advantage of our American good nature.
Then when you look closely at the moral fiber (or total absence thereof) of France, Russia, and Germany at the turn of this century, it looks alot like Germany in the 1930's. Confused, alienated, disillusioned masses scapegoating Jews (and now Americans as well) as a means of taking out their frustration at their own decline.
