I doubt this would happen because this would be the biggest foreign policy disaster in American history. This makes the Bay of Pigs look like the invasion of Grenada. (Also, it's not workable in practice, because the USA can't realistically "restrain" Israel.)
If these Iran-deal details are correct , they’ll make the JCPOA look like Hirohito’s surrender in 1945
