If Prime Minister Justin Trudeau truly believes that U.S. President Donald Trump is not joking about annexing Canada, he certainly isn’t taking it as a serious threat. If he were taking it seriously, he would never have prorogued Parliament — or, at the very least, he would recall the House of Commons now. Instead, Trudeau and those angling to replace him next month continue to operate under the fiction that all countries are fundamentally equal and that the United States, while certainly more powerful and more wealthy, is just like any other state living under the “rules-based international order.”
