Every American who immigrated from a foreign country in search of employment because their foreign country's government and society was completely screwed over by American interventionism is laughing and crying was they watch the rest of the world come to the same realization that the name of the game is who can suck Uncle Sam the fastest, and that almost every nation has been playing this game for 80+ years.
For a lot of people, this isn't even new. The only difference is now the top donors, NATO, are being discarded just like what happened to SEATO.
I would bet cash money that if Trump invades Greenland, NATO or EU will do jack all about it.
I would even bet hat even after we elect a new president, we won't leave Greenland without requiring a massive military outpost there.
