Once we nuke Iran, China & Russia will dump everything they have onto the U.S. and the U.S. will lose everything. WWIII will have broke out, and bush will be blame 4 starting it. The mexican army along with other nations army will cross over to the U.S. and we will be stuck fighting our own battle because all our soldiers will be getting nuked in Iraq. I dont have enuff firearms & ammo to take out an army, just yet..
