Once Trump steals Greenland he is going to look at a map with the mercator projection of Greenland, Alaska and the continental united states and he will think ‘Canada is just right there in the middle; wouldn’t it be beautiful if they were all the united states.’ He will then commence serious moves to take Canada.
He’s not going to be able to steal it. If he wants to buy it, the cost would be in the 2 to 10 trillion range. Anything less would be Denmark shooting themselves in the face. And even with all their friends wealth plus what they’ve stolen, they can’t afford it.
