There is a temptation to laugh at Donald Trump ordering the Interior Department to rename Lake Ontario "Lake America." A poster board reading "Making the Great Lakes Even Greater" plays as farce, and it is meant to.
Trade talks between Washington and Ottawa collapsed last week. Canadian officials say the United States walked in with deal-breaking demands. What followed was a lake being erased from the map by executive order, days after Trump posted that the country did not expect to be "doing much business with Ontario any longer."
Trump is turning geography, one of the few things nations are not supposed to fight over with a pen, into a lever of humiliation against anyone who does not fall in line on trade. The Gulf of Mexico was the trial run. Lake Ontario is the sequel, aimed at a country that happens to sit inside America's own alliance structure, a NATO partner, one of its closest intelligence allies, a nation whose military Trump himself complained about defending "for nothing," as though mutual defence were a favour owed rather than an obligation shared.
What should worry us is not the renaming itself. New York will keep calling it Lake Ontario. Canada will keep calling it Lake Ontario. The Interior Department's Geographic Names Information System has no jurisdiction over how the rest of the world speaks. The worry is the method: that a serious economic disagreement between two allied democracies is now conducted through stunts designed to bait, embarrass and dominate rather than negotiate. Manitoba's premier, Wab Kinew, called it a rock band replaying its old hits for a fading crowd. He is right, but the metaphor understates the danger. A head of state who has learned that spectacle plays better than diplomacy is teaching every other leader watching, allies and adversaries alike, that international relations can be conducted as theatre, that agreements can be abandoned mid-negotiation without cost as long as the abandonment generates enough attention to distract from the substance.
Trump is reviving Gilded Age politics: the belief that raw assertions of dominance, tariffs as threats, borders redrawn by decree, alliances treated as transactions, are simply how a great power is supposed to behave, and that anyone offended by the display is the one being naive. Carney's response, that America can rename its lakes but not the facts of geography, was tellingly, the only adult voice in the exchange.
Every stunt lowers the bar for the next one, and every leader who learns that mockery costs nothing internationally will reach for it again. Discourse between nations, like discourse between people, is built on the assumption that words carry weight and that walking away from a negotiating table has consequences. Turn enough of that into theatre and eventually no one, allies included, knows anymore what a serious commitment from Washington actually means.
As with Trump's earlier renaming of the Gulf of Mexico to the Gulf of America, Thursday's order is expected to bind only US federal agencies and does not require recognition by Canada or any other country.
