Israel has nukes. At least 90 and possibly hundreds. If Iran attacks Israel it would be the end of Iran.
The question is why are you so excited for the Muslims, rooting for them over Israel?
The only player in this game I'm rooting for is the USA. What you're forgetting is that Russia is treaty bound to come to the aid of Iran....and Russia has nukes too.
This is the reason why Carter resisted demands for an invasion of Iran . An airborne invasion would have been a disaster due to the inability to get heavy weapons in sufficient quantities into the region quickly enough.
So why hasn't Israel stormed Gaza? Why is it holding back? The equipment and manpower are all in place so why are they just standing around?. Could Israel now be getting cold feet worried about what the Arab world's response might be or perhaps is harboring doubts about the American taxpayers willingness to foot the huge bill for the mountain of very expensive military equipment it will need to support a bloody house to house street fight?
