Might help to remember he is at war with everyone who isn’t far right, even citizens. Canada is seen as a country of liberals. Your conservative party could fit in with some of the democrats that he calls far left lunatics.
He is open to doing things like denying disaster relief to blue states for not voting for him and sending in the military to force them into enforcing hate.
With him there is no moral standard or relationship that matters besides if he can personally profit off of you. If he knows he can do anything to you and there is nothing you can do about it he will exploit that. It’s not about ties between countries but ties between your country and him personally.
His support is a little less than a third of the country. The majority of Americans still look at Canadians as close friends.
Dividing everyone was the goal. Is it disappointing what happened? Yes. Are we still falling for the tactics that caused it to happen? Yes
