Donald Trump’s threat to take control of Greenland “one way or the other” has shocked Denmark and Europe. After the US’s military raid on Venezuela, Trump’s plans for Greenland are no longer seen as mere talk. Europe fears these are serious moves driven by expansionism and US demand for minerals. Trump’s open disregard for international law creates a dilemma: should Europe confront or appease him? Stephen Miller, a Trump aide, said on CNN, “nobody is going to fight the United States” for Greenland. But recently, six European countries, including France, Germany, Spain, Italy, Poland, and the UK, issued a joint statement. They said Greenland belongs to its people and Denmark alone, nothing for the US to claim. Denmark aims to calm the crisis in Washington and insists Greenland is not for sale. Greenlanders have mixed feelings about Denmark, but both governments stand together for now. Meanwhile, US Vice-President JD Vance might push ideas like buying Greenland. Experts say Trump's claim that the move protects Greenland from Russia or China makes little sense. Greenland has semi-autonomy but is defended by NATO under Denmark. The US could increase security without annexing the island by using existing treaties. Alarm is growing in Greenland, where many fear what Trump might do. The UK, under Keir Starmer, hopes to find a peaceful solution. Starmer has spoken with Trump about protecting the Arctic against Russia. His foreign secretary, Yvette Cooper, pressed NATO to enhance Arctic security, indirectly addressing the tensions. Europe is cautious but considers strategic moves. Robert Habeck, former German vice-chancellor, suggests Europe offer Greenland EU membership and large investments to resist US pressure. Fabian Zuleeg of the European Policy Centre says Europe should hit back where it hurts Trump politically, like trade and market access. Some see the Greenland threat as a sign of US fascism and call for strong measures, even pushing the US to leave European military bases. For now, Europe must balance diplomacy and power to protect Greenland’s future and its own security ties.
