Well, what can i say except for:
Piss people off, and you're going to see sh!t flying around your head. The USA has been pissing people off for decades, so it's not a surprising event.
If people are desperate enough to give their lives for a cause, they must be pretty desperate, desperate enough to do major insanity. the ONLY way to stop those desperate actions is to give them an escape from their desperate situation, and NOT kill every single one of them.
ofcourse, that won't happen, and the USA will just bomb the hell out of innocents, as usual.
