Canadians who oppose Trump, or support Carney, or both, might respond to these examples by saying “Trump started it.” It’s true that Trump initiated this trade dispute by ushering in a series of policies aimed at changing the global economy. But Carney knew that when he signed up for the job of prime minister. When asking for Canadians to elect him, Carney promised he could deal with the situation. At no point did he say that he would actively make it worse, or that he would use the prime minister’s office to advance the interests of the Democratic Party over Canadian workers.
