If Canadians are worried about Trumps threats of absorption, then I as a citizen of an independent Alberta would be petrified.
Canadians like to argue that no province can secede from Canada because it would be illegal but the reality is that if a referendum showed 50%+ of people in Alberta supported independence then the US would support Alberta and that’s the only thing that matters. A lot of Canadian press is wilfully ignorant of that fact.
I don't make a habit of ignoring major world powers when they threaten annexation, and many others who are "paying attention" don't either.
Trudeau is no longer here, those threats continue to be made, even in the _presence_ of the current leader of Canada. I don't understand how one could not take these threats seriously.
