Denmark is rushing soldiers, warships and air defences to Greenland after Donald Trump renewed threats to “take over” the Arctic island, forcing Copenhagen to turn a distant territorial concern into an urgent NATO mission that affects everyone living in the Danish Realm.
I’ve watched Denmark navigate Trump’s tantrums before, but this time feels different. Within days of the former president again claiming Denmark cannot protect Greenland and hinting at U.S. seizure, Defence Minister Troels Lund Poulsen announced a significant military build up in and around the island. Aircraft, ships and ground troops are deploying now, not next year.
This isn’t just Arctic posturing. Greenland is part of the Kingdom of Denmark, home to 56,000 people including thousands of foreign workers in mining, research and logistics. Any escalation puts them on the frontline of a confrontation Denmark never asked for.
NATO allies answer Denmark’s call
Politiken reports that soldiers from multiple NATO countries are heading to Greenland, with several European governments signalling readiness for a coordinated mission. Greenlandic politicians across key parties have backed the plan, framing it as protection of self rule rather than an erosion of autonomy. That support matters because Greenland enjoys extensive self government under Danish law and has a right to self determination under international law.
As reported by TV 2, Poulsen stressed there will be an increased military footprint through 2025 and 2026 under the Arctic Endurance exercise. The army chief is flying to Greenland with additional troops as a direct response to Trump’s latest outburst. Poulsen labelled the threats unacceptable, noting they target Denmark, Greenland and NATO allies in an already tense security environment.
Walking a tightrope between Trump and Greenlanders
The dilemma is obvious to anyone who has followed Danish Arctic policy. Denmark insists the build up defends against Russia and China, but everyone knows it also aims to placate or deter Trump. The Danish Institute for International Studies warns it will be difficult to make both Trump and Greenlanders feel safe at the same time.
I’ve seen how Denmark likes consensus, but militarisation is divisive. Critics in Greenland and among scholars argue that heavy NATO branding may weaken perceptions of Greenlandic self determination if local consent looks secondary. Environmental groups oppose more military traffic in fragile ecosystems, though that concern has been drowned out by security talk.
The official line emphasises consultation with Nuuk, but decisions are being taken in Copenhagen, Brussels and Washington. Ordinary Greenlanders and the foreign nationals living there have little say in a process that could reshape their home.
What Trump wants and what Greenland gets
Trump first floated buying Greenland in 2019, sparking a diplomatic row and a sharp rebuke from Copenhagen and Nuuk. The idea was laughed off then, but his return to the political stage has revived the threat with more menace. Denmark technically owns Greenland under international law, but Greenlanders hold the right to decide their future under the 2009 Self Government Act.
Legal experts suggest preventive measures like a UN General Assembly resolution reaffirming the prohibition on forcible annexation. Canadian Arctic law scholar Michael Byers has urged NATO allies to send small military units to Greenland on exercises with Danish forces as a visible deterrent. Denmark is now doing exactly that, turning theory into boots on the ground.
What it means for expats in Denmark and Greenland
For foreign nationals in Denmark or Greenland, there are no immediate changes to residence rules, work permits or travel. The Aliens Act and standard permit frameworks remain in force. But the political mood is shifting. Defence spending is rising toward two percent of GDP by 2030, with tens of billions of kroner earmarked for Arctic capabilities including surveillance radars, drones and air defence systems.
Expats in Greenland may notice infrastructure changes tied to defence upgrades, temporary access restrictions during exercises, and increased military traffic through airports and ports. Journalists and NGO workers should monitor advisories from the Joint Arctic Command and local Greenlandic authorities. In any serious incident, foreign nationals should follow instructions from politi.dk and their home country embassies.
Living in Denmark means accepting that geopolitics now intrudes on daily life in ways it didn’t five years ago. Finland and Sweden joined NATO, Norway expanded Arctic exercises, and Denmark is enlisting European allies to guard an island most Danes rarely think about. That island is suddenly the centre of a standoff with an unpredictable American politician, and everyone in the Kingdom is along for the ride.
