Lots of speculation about whether the Americans (or the Israelis) will hit Iran, perhaps even with nuclear weapons. The real question is, can they be that crazy?
One line of thought is that the Bush people put out the nuclear story to set up public expectations. The idea is that if they then go in for conventional bombing, instead of being outraged, people will breathe a sigh of relief.
Anyway, having been burned with the WMD boogy man once, we are sensible to be skeptical. Who said "Fool me once, shame on you, Fool me twice and---uh---uh---can't fool me." ?
The real reason Bush wants to take out Iran has nothing to do with nukes.
