With a POD after, say, 1941, create a Cold War where it's mainly between the U.S. and the USSR, (with a PRC either allied to the USSR or hanging off on its own, plus a third-world non-alignment movement not doing much other than being made pawns), but also including a third side based in Europe that's pretty much hostile to both sides (like the PRC post-Sino-Soviet split).
The biggest options are:
All of Western Europe: Doesn't make any sense for NATO to kick the U.S. out, so this option is pretty implausible. I don't think that during the Cold War the entire continent of Europe would get angry at the U.S. at once to warrant such behavior.
The United Kingdom: This requires some sort of POD in which the British empire doesn't fall apart as soon. I think that since we're assuming an Allied victory, the Allied nations are mostly likely to walk away nearly intact. Well, maybe Italy as well, but the Italians never had a big empire as a base to become a major power anyways.
France: Could they pull off a For All Time sort of fascist turn, retain their colonies, and become a lose agent to mess with the U.S. and USSR?
