The economic punishment and threats of aggression that Donald Trump has launched against Canada are so severe that its government has looked at how to prepare for U.S. military action. David Remnick sits down with a former senior Canadian politician, Chrystia Freeland, to talk about the disintegration of a rock-solid partnership. Freeland served as the Deputy Prime Minister under Justin Trudeau, and has also held the roles of Minister of International Trade and Minister of Foreign Affairs; she helped negotiate a trade deal in Trump’s first term, which he subsequently broke. Freeland’s new book about the U.S.-Canada relationship is called “Unreliable Boyfriend,” but that title may soft-pedal it. “The vast majority of Canadians see this as a rupture” that will be permanent, she tells Remnick. “They think America is toxic and broken and can never be trusted again. . . . I actually am an outlier, because I think we shouldn’t write America off quite yet.”  Further reading: “What If Canada Joined the E.U.?,” by Ishaan Tharoor “Canada, the Northern Outpost of Sanity,” by Bill McKibben “The Historical Roots of Donald Trump’s Aggressive Nationalism,” by Isaac ChotinerThe Political Scene draws on the reporting and analysis found in The New Yorker for lively conversations about the big questions in American politics.
