America totally sucks at actually annexing territory (so, not merely conquering, but actually all the way to making it part of its own territory), with the last successful instance of doing it being Puerto Rico during the Spainish-American War back at the end of the 19th Century.
So of those you listed, maybe Greenland would be possible to actually annex due to its tiny population - Americans could literally just kick everybody else out, by which point the place is just empty land which can be treated like some kind of North Atlantic oil platform that just happens not to be floating, which is fine if all you want to do there is exploit mineral resources that don’t require much manpower to extract - as well as the small european occupied islands like Azores (though what would be the point of getting Azores since it has zero mineral resources and the only real value of its economic exclusive area is for Fishing which is a low economic value activity that requires quiet a lot more manpower than oil extraction).
Certainly actually annexing a South American country would almost certainly turn into a quagmire for America in the same style as Vietnam.
I mean, if you currently look at Venezuela, for all of Trump’s strutting like a rooster on it, it’s not actually occupied by America (zero boots on the ground) and any real American gains extracted from it (which in reality are far less than Trump’s proclamations would make it seem) come from literally blackmailing the individuals in leadership there with “if you don’t do what I demand I’ll do to you personally the same I did to Maduro” - that situation is not at all one where America owns Venezuela.
