If Isreal- embattled and surrounded by enemies on all sides thought that they were going to be attacked or even saw a nuke threat they would have pulverized that threat like they did in Iraq in 81.
Yup, and that is why America is going to do the hard work.
If Israel is forced to fight, then it will probably go nuclear.
America has the conventional forces to remove this danger, and prevent a release of nuclear weapons.
This is our choice, and so far, the wise one to follow.
