Prime Minister Justin Trudeau gave an interview to the New York Times in December that deserved far more attention than it got. “There is no core identity, no mainstream in Canada,” Trudeau said, adding that Canada is the world’s first “post-national state”. Is that what Canadians will be celebrating when the country turns 150 next year? Mark Milke hopes not, for he contends that a country without a national identity is a country without a future. Trudeau seems not to have noticed, but he may have framed the next big debate between progressives and conservatives.
