India, John Keay, gives a good picture of "moderate" Islam vs. "fundamentalist" Islam during the Mogul, Moghul, Muhgal, era; you might also want to look into the "Old Man in the Mountain" and his (their) "hashshashin, hashishin, assassins" --- depending on sources, they look a lot like the model bin Laden styles himself after, or you'll read that they're "apostates." Sunni, Shia, Wahabi, this, that, and the other Caliphate, and the squabbles among them all have been going on for a millennium. The point being that they've been making a colossal mess of the cultures, politics, and social structures of the area for well over a thousand years. Acknowledgment of the root of the squabbles, who's got first dibs on the collection plates, is never made by any of the parties to the squabbles; the squabbles are instead attributed to the actions of outsiders, infidels, "the Great Satan," and any other number of puerile excuses, much the same as the "fact" that no group of 8-12 year olds have ever put baseballs through neighbors' windows --- birds swooped down, grabbed the ball and dropped it, it rolled into the street and a passing truck squeezed it under a tire and it popped out like a watermelon seed, a passing biker gang grabbed it and deliberately threw it through the window --- you can as easily attribute "the rise of fundamentalism" to the rise of the "dial an excuse industry" Freud started --- they aren't fundamentalists because they're ignorant, greedy, vicious, vindictive people --- they're fundamentalists because 90% of the world's population enjoys a better standard of living without Islam, and it makes them look and feel bad about themselves --- we've destroyed their "self-esteem."
Sorry about that. (And its aggression not agression)
