Ah the old what if US + Israel and west attacks Iran. Has it not been debated hundreds of time. The result without Russia and Chinese help would be an Iran left like Afghanistan (if the Americans are so polite as to do so)..Simply to the rest of the world it is just another Iraq no different and hopefully Americans will bleed more. What do Iranian Mullahs want Russian and Chinese to make it WW3 haha dream on Iran is a body shield no offence to fellow Iranian members.
