Right now Iran does not have nukes. Russia probably won't fight for Iran because they know that attacking Israel means angering the US, which is bad for any nation. About half of Europe is in NATO, so unless they break that alliance they're siding with the US. India probably also won't get involved, as Israel simply doesn't concern them. I doubt it would get nuclear, as MAD just ruins everyone's day. And seeing how NATO accounts for about 40% or so in military spending in the world, that's a lot to contend with. Not including other nations like Israel, S. Korea, Japan, Australia, or New Zealand. NATO would likely win a conventional war.
