You keep talking about a war of attrition, nuclear strikes don't fall in that category at all.
Once again you are sadly mistaken thinking Israel will wait fot the US ok to do WHATEVER they deem necessary.
I seem to remember them selling weapons systems to China without any prior approval.
Israel is not going to nuke the entire ME with over 200,000+ U.S. soldiers on the ground. Not gonna happen.
Israel is not going to nuke Iran either. That is foolish speculation.
