What would have happened? What would a post-war world look like?
I don't believe in this "3-way Cold War" thingy. "USSR vs. everyone else" is more likely. If USA could befriend Mao as soon as he became anti-Soviet, there's nothing to prevent Nazi and America working mano-a-mano.You probably end up with a three way cold war with America, Nazi Germany (with most of central and western europe) and the USSR.
