For Canada, though, America’s disrespect and intimidation are now standard issue. The U.S. ambassador to Canada, Pete Hoekstra, seems to have been installed primarily as an insult engine, tasked mainly with belittling his hosts wherever and wherever possible. (His advice to Canadians upset by Mr. Trump’s remarks that Canada should be the 51st American state: “Move on.”) Recent revelations that U.S. officials have been meeting with Albertan separatists have indicated that the Trump administration may not have given up on the idea of Canada’s dissolution. Threatening one’s neighbors, as Canada has learned the hard way over the last year, is a hallmark of autocracy-minded leaders.
