I'm not familiar with the author and don't know his reliability or experience with the subject. However, I have a little trouble believing that bin Ladin's money isn't finding it's way into at least some of the pockets of Bedouin tribal leaders.
interesting take, but the idea that individuals are possibly insprired by osama's words and not money does not bode well for us. from what i read elsewhere the attacks in sinai did not cost much, so is it really osama's money at work here?
