I don't think that this is something Bush would want. Gas prices hurt them and Jerome is absolutely right, attacking Iran would make it worse for a long while. Even an invasion of the country would not guarantee the production. (See Iraq.)

I believe Bush is honestly worried about a nuclear Iran. But even more so, I believe that people do not appreciate how much the nuclear issue is a domestic one -- for Bush, but especially Ahmadinejad. They both need their people to be tense and on the edge for now. But war is not either one's realistic goal. Ahmadinejad may even want -- he probably does -- aerial attacks, so that the country unites behind him, but he would not want an all out war either. In my opinion.
