I have this war game dream where I'm POTUS and I ask the Russians and the Chinese, "If the Muslims nuke Israel and I come to Israel's defense, up to and including nukes, what would you rather do: oppose me and defend the Muslims, or do nothing and get an ally's share of the oilfields?"
It always ends the same way.
Man, I don't even think that discussion would be necessary. Russians and the Chinese would be *thrilled* to be rid of the islamists that are inciting issues in their countries (as well). They'd just call to negotiate as to which areas they get. Probably even offer to "test" some of their own ballistics.
