A well educated guy spent some time in Pakistan to try and figure out just what the hell is going on over there. His conclusion? It's complicated, but still explainable. My paraphrase: the paks are a bunch of paranoid nutjobs looking to blame everyone but themselves, and the US in particular, for the mess they're in. No wonder they get along with the Arabs so well.
All jokes aside, this even-handed report agrees entirely with longer book-length treatises on the subject that I've read. It's a good primer that won't take long to read which will give you a much better idea of what's going on in the real hotbed of Islamic terrorism.
