Tensions are rising across the Arctic as European NATO allies rush small troop contingents to Greenland amid U.S. President Donald Trump’s renewed push to acquire the island, a move that has alarmed Europe and exposed fractures inside the alliance. France and Germany are leading the deployment, while other NATO members send symbolic numbers of personnel — a show of support for Denmark that critics say underscores Europe’s limited military posture against U.S. pressure. As Trump signals Greenland is a national security priority and Washington confirms ongoing talks on acquisition, European leaders warn that any U.S. attempt to annex territory from a NATO ally would shatter the Western security order. The standoff highlights a deepening transatlantic rift over Arctic security, sovereignty, and Trump’s unpredictable foreign policy agenda.
