Utterly ridiculous. First of all the Iranians have nothing to put up in the air that could resist the Israel Air Force, and US Air forces could take of Israel in 30 minutes. So without an air force Iran would have to fight air from the land, that means Radar guides missles and guns. Might take a while to get them but once the radar turns on those sites become targets, once the air defences are taken out the 52's and other bombers come in a wipe out the ground forces.
I hope the Iranians really believe this crap they are putting out, they had a date with US forces for a long long time. Jimmy chickened out I don't think that will happen again.
