“I want tariffs,” President Trump was recently quoted as having said. He also said, off the cuff, he would “end up probably terminating NAFTA.” Either one would be a catastrophe for my home country, Canada, and not just economically.

Overwhelmingly, it is American sperm and American blood plasma that makes and saves so many Canadian lives.
