[shrugs] Everything costs money. The "Islamic Revolution" is no different. It's happening because someone is paying for it. And someone is paying for it because it furthers that particular power bloc's agenda...
Knowledgable posts around the forum seem to agree that bin Laden's "organization" was, basically, a kind of mercenary group. They worked for whatever power bloc/money source was most profitable to them. If they flew planes into buildings -- or provided resources of one kind or another to such an operation -- then I imagine the "real" reason they did it will eventually be seen to be the reason mercenaries do anything -- for the money. (I'm not saying the suicide pilots were in it for the money -- I'm saying that the organization which supplied the suicide pilots probably made a profit on the deal...)
(By the way, good pithy response to a two-month old post... [smiles])
