Trump proposes expansion of U.S. territory with plans for Canada, Greenland, and Panama Canal

President-elect Donald Trump has proposed expanding U.S. territory by encouraging Canada to become the 51st state, purchasing Greenland, and reclaiming the Panama Canal. These ideas have drawn comparisons to 19th-century American expansionism. Trump announced a 25% tariff on goods from Canada and Mexico until they address drug trafficking and illegal immigration. Canadian Prime Minister Justin Trudeau has responded to these tariffs, but no major Canadian political party supports joining the U.S. Trump's suggestions for Greenland and the Panama Canal echo past U.S. territorial ambitions. Danish officials have previously rejected the idea of selling Greenland, and the Panama Canal was handed over to Panama in 1999.
