Iran is not a superpower, it is in effect a weak regime strengthened by ruthless collaboration from Europe. There will be two strike targets, first one against the military and their missile system, later on against their nuclear sites. The mullahs will have no command and control and all they can send are their basijis and their exploding grandmas. The military dangers involved are not much greater than the ones we have seen during the first Gulf War called the mother of all battles. Apart from pin point commando operations there will be no US ground forces in Iran. It will depend on the Iranians to take back their country from medieval mullahs. In any case Iran will be a country without a military attacking potential and for sure a country without a military nuclear program. Do not forget that we saw going down the FSU. Why are you constantly whining when it comes to a few medieval mullahs?
