Reports that the UK is considering contributing troops to Greenland have put Arctic security back in focus, after remarks by Donald Trump raised concerns among European allies.
According to Reuters, Britain and Germany have discussed options for a NATO role in Greenland aimed at easing tensions and reinforcing existing security arrangements, rather than altering sovereignty. Other news outlets report that UK Prime Minister Keir Starmer is considering a contribution.
Greenland’s prime minister said, “We don’t want to be Americans, we don’t want to be Danish, we want to be Greenlanders.”
Trump told reporters at the White House on January 9, “We are going to do something on Greenland whether they like it or not. Because if we don’t do it, Russia or China will take over Greenland, and we’re not going to have Russia or China as a neighbour.”
UK involvement in a NATO Arctic mission
The key point for readers is that no UK deployment has been announced. The discussions reported by Reuters relate to contingency planning within NATO, as allies look at ways to reassure the United States while maintaining alliance unity.
Belgium’s defence minister, Theo Francken, has suggested a limited NATO surveillance operation – dubbed an “Arctic Sentry” mission – modelled on existing alliance deployments that rely on joint forces, drones and monitoring rather than permanent bases.
Geographically, Greenland sits close to the GIUK gap (Greenland–Iceland–UK), a critical maritime passage between the Arctic and the Atlantic. A European Parliament research brief describes it as a key transit route for naval forces between regions.
What a NATO Arctic mission could look like
Despite the heated rhetoric, analysts describe any NATO role as limited and defensive. Based on proposals cited by Reuters, it would likely include:
- Surveillance and reconnaissance, using maritime patrol aircraft, satellites and drones.
- Maritime patrol and anti-submarine monitoring, linked to the GIUK gap.
- Cold-weather training and logistics, through short rotations and joint exercises.
- No change to sovereignty, operating only with Denmark and Greenland’s consent.
Greenland already hosts US defence assets under long-standing treaties, and current discussions focus on reassurance and coordination rather than escalation.
