Surely you jest. Even Bush can't be stupid enough to attack Iran. Unless we use Nukes, we have no chance of defeating their million man army, They would swarm Iraq and kill every American in sight with help from the shia militias, and then kill all the Sunnis and what Kurds didn't surrender. Then you'd have one Giant Iran with both countries oil reserves, Remember, Iran has tanks and planes and missles and heavy artillery, and maybe even a borrowed Nuke or two. This would mean certain defeat for the US. (Unless we use nukes), then it's on, Russia, china, Packistan, India, would all jump in and Armegeddon here we come! And if it looked like we were gettin our asses handed to us, Isreal would probably Nuke them anyway, as they know they're next!
