Trump warns he could cause the ‘ruination’ of Canada

Returning to his bellicose trade rhetoric, U.S. President Donald Trump warned Friday that he would cause the “ruination” of Canada if he imposed tariffs on Canadian-made cars.

Trump has repeatedly threatened to hit Canada with the auto tariffs if Prime Minister Justin Trudeau refused to make NAFTA concessions. He had never before spoken about ruining Canada, but it was not clear if the rhetorical escalation was a deliberate, meaningful shift or merely impromptu loose talk.
