Conrad Black analyzes the impending trade dispute between Canada and the United States, labeled "the dumbest trade war ever." President Trump's comments describing Canada as a "51st state" and calling the Prime Minister "governor" have sparked deep resentment across Canada.

However, the political opposition is demanding that Carney publish the underlying negotiation documents and recall parliament to build an all-party policy. Black argues this represents a moment of great risk but also a Churchillian opportunity. (5)
