I don't think Bush is going to be able to go to war with two countries at the same time in two month's time. His support, and support for the Iraq war, is abysmal. People see what's going on in Iraq, and I doubt many actually expect us to be able to effectively fight an Iranian resistance, with three times the land and three times the population, PLUS a Syrian resistance as well.

And I highly doubt that Saudi Arabia is going to be invaded any time soon. Bush is not on a crusade to invade every Muslim nation he can. The Saudi dictatorship has served US interests well, and as long as they continue to do so they have nothing to fear from him trying to "liberate" their people from their oppressive régime.
