Russia would either stay neutral or be on NATO's side, going to war would only destroy 20+ years of repairing relations with the West.

Remind you that Iranian terrorists have carried out (failed) terrorist attempts in Russia recently so no way Russia would join them.

I'm not so sure that the US would even come to Israel's defense anymore. Obama has spoken against Israel's presence in the West Bank numerous times, although the military itself is staunchly pro-Zionist.

The only real problem is Pakistan, who'd likely come to defend the Iranians, which would trigger conflict with the Indians and theres your WW3 :P
