Trump has declared an intention to rename the Gulf of Mexico to the "Gulf of America," stirring controversy regarding trade and immigration.
His comments included criticisms of Mexico's policies and claims that the US does the majority of work in the region, asserting it "belongs" to America.
Trump threatened significant tariffs on both Mexico and Canada, citing concerns over drug trafficking and a trade deficit.
He proposed a potential US-Canada merger following Canadian Prime Minister Trudeau's resignation, heightening political tensions.
Historical experts caution that renaming the Gulf could lead to international backlash and further strain North American relations.
