So, a war is brewing over there and the sides are being Drawn now. Goal is to outnumber Iran. Though Isreal would have the backing of the UN would they not?
I would definitely not count on the UN, no. That organization is corrupt beyond belief, and there are plenty of countries sympathetic to Iran on there. But yes, the goal is to stand united against Iran so Israel, the Gulf countries and Saudia can't be defeated in detail, and to coordinate their own responses against Iran.
