It all began with a tariff dispute between the United States and Canada. The two nations held negotiations over overhauling the North American Free Trade Agreement framework and readjusting tariffs. However, when talks ultimately broke down, the Trump administration took hardline measures. It imposed a 50% retaliatory tariff on major Canadian imports worth about $20 billion, including lumber, dairy products, and cement, while also exerting pressure to extend the levies to the automotive and steel sectors. Yet, Canada did not back down. Canadian Prime Minister Mark Carney declared that Canada "will not yield to unilateral threats from the United States." Canada raised tariffs on U.S. steel and aluminum from 25% to 50% and announced tariffs of up to 50% on $20 billion worth of U.S. goods, including agricultural machinery, electronic devices, and home appliances. It fought back with an eye-for-an-eye, one-to-one retaliatory tariff strategy.
President Trump then played the card of renaming Lake Ontario, one of the Great Lakes bordering Canada, declaring it would be changed to 'Lake America.' At first, it was thought to be a mere threat. However, on the afternoon of August 27 local time, he formally signed an executive order in the Oval Office to immediately change the name to 'Lake America.'
This is not the first time President Trump has altered a well-established geographical name. Early in his administration, he renamed the 'Gulf of Mexico' to the 'Gulf of America.' That, too, occurred amid a power struggle with Mexico over tightening border controls, curbing drug smuggling, and resolving trade imbalances. The stance was so uncompromising that the White House denied press access to the Associated Press for adhering to the name 'Gulf of Mexico.' In effect, the U.S. has clashed over place names with both of the only two countries sharing its borders.
Although sparked by a tariff war, this battle of pride is being pursued in earnest by both nations. The U.S. immediately put the executive order into effect. On the U.S. edition of Google Maps, 'Lake Ontario' has already been changed to 'Lake America.' The name 'Lake America' is now used across maps, official documents, and geographic information systems of U.S. federal government agencies.
In response, the Canadian province of Ontario installed a massive sign along the lakefront. On the billboard, which reaches the height of a two-story building, the phrase "Lake Ontario. Now and Always" is displayed side by side in both English and French. Prime Minister Carney also pushed back, noting that the name Lake Ontario predates both the founding of the Canadian Confederation and the U.S. Declaration of Independence, declaring that it is "Lake Ontario in the past, in the present, and in the future." He emphasized that the name Ontario derives from the indigenous Wendat word meaning 'beautiful lake' or 'great lake' and has been used for more than 400 years.
Fifty-two percent of Lake Ontario's surface falls under Canadian jurisdiction, while the remainder belongs to New York State. The border between the two countries has long been established. A geographical name change does not affect the legal or practical advantages in border disputes. The legal status of high seas or shared waters cannot be altered solely by an executive order from a single country. Furthermore, a name change by the U.S. Department of Justice or the U.S. Board on Geographic Names applies only to domestic administrative agencies and cadastral maps within the United States. There is no international legal obligation whatsoever to adhere to this name. Standard diplomatic practice dictates using diplomatic leverage to secure practical gains and maximize mutual benefits. From this perspective, renaming a landmark without justification or tangible gain, while merely offending the pride of a neighboring country, is clearly a losing proposition. However, under Trump's framework of transactional diplomacy and domestic-focused foreign policy, the calculation is entirely different.
First, it serves as a tactic to secure negotiating leverage through symbolic intimidation. In matters of substantial consequence such as tariffs, trade negotiations, and border issues, it acts as psychological warfare to throw the opposing country off balance and seize the initiative. While the name change itself yields no tangible return, it projects a message of unpredictability to foreign governments—signaling that he will not hesitate to cross conventional and diplomatic boundaries. It functions as a form of "madman theory" designed to impose psychological pressure.
It also operates as a political rally-around-the-flag strategy for domestic audiences. Foreign policy actions are utilized as political showmanship to unify the support base. It visually demonstrates the 'America First' branding, maximizing American supremacy and patriotism. Through this, it delivers strong satisfaction to supporters, giving the impression that he has exercised American sovereignty and restored national standing in ways that conventional bureaucrats never dared to attempt.
Another evident objective is to induce the waste of the counterpart's national resources through asymmetric costs. For the United States, it is merely a single executive order, but defending against it consumes enormous diplomatic, administrative, and public relations energy from Mexico or Canada. While Canadian or Mexican politicians and media become entangled in outrage and expend resources responding to the geographical name controversy, the U.S. aims for higher ground in substantive trade talks, such as tariff and regulatory adjustments.
Finally, there is an intention to dominate the media narrative by overshadowing other issues. It diverts media attention away from unfavorable domestic and foreign political issues or controversial policy failures toward provocative headlines concerning sovereignty. By introducing fiercely polarizing topics, it seeks to drown out various controversies and maintain control over agenda-setting.
Traditional diplomats unanimously argue that the costs are far greater, as it only deepens diplomatic isolation and fuels global anti-American sentiment due to foreign backlash. In contrast, Trump and his aides calculate that the sentiments of foreign publics and diplomatic trust are difficult to quantify and produce long-term effects, whereas the cheers of the domestic base and the pressure placed on foreign governments are immediate and tangible. This serves as a stark example showing that diplomacy is defined not as a platform for mutual cooperation, but as an extended stage for domestic politics and a zero-sum arena. However, the core of the "madman strategy" driven by unpredictability lies in shock value and pressure. While it may work once or twice, its effectiveness diminishes when repeated, as counterparts eventually decipher the pattern and devise counterstrategies.
A greater problem is that closest allies such as Canada, Mexico, and the European Union will no longer view the United States as a reliable partner. They are likely to pursue self-reliance strategies to reduce dependence on the U.S. by building independent supply chains and strengthening multilateral cooperation. Weakening solidarity with allies inevitably undermines the capacity to respond to adversaries. Over the long run, the costs of maintaining hegemony are bound to surge sharply.
The domestic political fallout will also turn negative. If retaliatory tariffs and trade friction persist, the U.S. will see cumulative economic damage, particularly among farmers, manufacturers, and consumers. While the public may cheer momentarily over a display of national pride, sustaining such nationalistic fervor becomes difficult once livelihoods deteriorate. Ultimately, it faces the criticism: "What tangible benefits were gained by inviting international isolation?"
Trump's diplomatic strategy is possible only because the country is a hegemon. Conversely, in the long term, it is also a grave miscalculation that threatens its very status as a global hegemon. This remains the biggest blind spot for Trump, a lifelong dealmaker.
