United States President Donald Trump has indicated he may impose tariffs on countries that do not support United States control of Greenland. This statement comes amid ongoing diplomatic tensions, as a bipartisan Congressional delegation visits Denmark to ease relations. Trump has repeatedly asserted that the United States should control Greenland, calling any other outcome 'unacceptable.' He referenced previous threats of tariffs on European pharmaceuticals and suggested similar measures could be used regarding Greenland, citing national security concerns.
