Donald Trump says a “deal on Greenland” could be a condition for the United States to keep its troops in Europe, according to reports after he spoke on his return flight from a NATO summit. Trump frames Greenland—an autonomous territory within the Kingdom of Denmark—as a potential area for a US arrangement. In the reporting, he suggests Greenland should come under US control, tying the issue to broader questions about the future presence and role of American forces in Europe. The outlets describe his remarks as linked to negotiations or leverage related to troop deployment rather than as an immediate policy decision. The reports are consistent in their account that Trump connected Greenland to sustaining the US military footprint in Europe, but they do not provide further details on the terms of any proposed arrangement or responses from Denmark or NATO partners in the material provided.
