Donald Trump will become U.S. President on Jan. 20. He’s already given some indication of what he’s thinking of doing when he returns to the White House. It may be bluster, and it may never materialize, but the next Liberal Prime Minister — and Conservative leader Pierre Poilievre, who seems destined to become PM — must be prepared to deal with it.

The President-elect went on a tear at a press conference yesterday. He mused about changing the Gulf of Mexico’s name to Gulf of America, which he suggested had a “beautiful ring” to it. He didn’t discount military action to take control of Greenland and the Panama Canal, believing the U.S. needs them “for economic security.”
