For months, many Canadians hoped Donald Trump had lost interest in making their country the 51st U.S. state ¡ª his plate full with turning Washington and the global trading system upside down.

The administration¡¯s declaration that ¡°THIS IS OUR HEMISPHERE¡± makes Trump¡¯s earlier comments about annexing Canada seem ever less like mere insults aimed at former Prime Minister Justin Trudeau, or negotiating tactics in his trade war with current leader Mark Carney.
