I think it would be interesting to ponder what would happen if we pulled out of the Middle East entirely. I would suspect that Israel would become enemy number 1 (if it isn't already), and there would be a muslim war against the Jewish state, condemning them for their "oppression" of Palestine.

Though I could see us sending them arms, perhaps even WMD's, to aid their cause? Just a theory, mind you. But it would keep the US hands clean. Clearly, Israel knows how to take care of business, as they obliterated the PLO from Lebanon in the 80's (despite the western media's outright rejection of the actions as illegitimate).
