I don't go with that. China would have some serious concerns as would Russia. I think it is because of those two countries that America is loath to make the first move. However, secretly I believe America would prepare itself to jump in to aid Israel if she started. Obama may lay on his back and P up his belly like a puppy when it goes off, but the alternatives are too dire to contemplate, if he does nothing and nukes are smuggled onto American soil.
