> I think the US could seriously pull out of NATO and leave the EU to fend off Russia by itself. It'll have to start spending enormous tax dollars on defense and war.

Disagree. If US pulls out of NATO, most likely scenario is EU continue to concede to Russia. I think EU will concede on Greenland too, but likely won't do it without any military action (unclear whether that will trigger nuclear escalation and how that can end).
