Women (Nasty or otherwise) are going to be the reason that Donald Trump is NEVER President!
Your imaginings about a nuclear world war have a sort of drama queen ring to them. There is no reason to believe that a nuclear attack by Iran on Israel would cause any nation other than Israel to use its nuclear weapons.
I doubt the Khomeinist murderers who rule Iran have the stomach for an overt nuclear attack Israel, if they get the bomb, but they would not need to use a missile and leave no doubt where it had come from. Iran has many willing suicide squads in Hizballah that could hide an atom bomb in an ordinary truck, drive it into a city, and go up with it. That would leave no clear proof Iran was behind the attack, and it's at least questionable if any Israeli government would be willing to kill millions of Iranians in a counterstrike based only on strong suspicion.
Neither. I don't trust the government of Israel as far as I can throw each of it's members. However, the US has no place interfering in Middle Eastern affairs.

I have a pretty good knowledge of the history of British and French appeasement of Hitler and Mussolini from 1934 to 1939, and I know very well what appeasement means. President Pinocchio does not wish this country well, and he has been kowtowing to the Khomeinist murderers in Tehran for six years. Not surprising for a man who had a Muslim father and stepfather, went to Muslim schools and had a Muslim college roommate, and counted the former PLO propagandist Rashid Khalidi among his closest friends in Chicago.
