I don't think that Arens is out of his mind, he just doesn't strike me as a very intelligent bloke. I'm all for learning, even the hard way, it's just that Moshe obviously hasn't learned much. Occupations don't work. He should know that by now. But I may be wrong and Moshe is not so dim, maybe he sees an occupation as a nice tool to feed his buddies in the military industrial complex, just like his neocon American counterparts have used Iraq as a wonderful tool.
