> Greenland leaves the Danish Realm

> Greenland becomes sovereign nation

Greenlanders don't want to become part of the USA afaik, but they know that in the current situation becoming independent means being invaded, sooner or later, by the USA, Russia or China, so I think that the scenario of Greenland trying to become a sovereign nation is less likely now.

As for Canada, although there are a number of Trump supporters that foam at the idea of invading their neighbor, I think that the invasion would be deeply unpopular (a number of people voted for Trump because he was supposed to stop the wars, not start new ones), especially if the Canadian population offer some kind of resistance although who knows, it is just a matter of enough propaganda...
