In fact, I now discover, the motive probably isn't even as clear-cut as that. Apparently there is no stated motive for the recent terrorist acts, which makes them seem even more pointless wastes of life in my opinion, but Al Qaeda (who are considered responsible for the attacks) simply do it because they hate the whole of Western society. The question that begs to be asked is: "what can men do against such reckless hate?" (Theoden, LotR:TT)
