Global attention has shifted sharply to the icy expanse of the Arctic, where diplomacy, defence, and territorial sovereignty are colliding in uncomfortable ways.
What might once have seemed like a distant geopolitical issue has now become a pressing test of unity for NATO and its allies, with Greenland unexpectedly at the heart of the debate.
Starmer Steps In to Calm US–Europe Frictions
UK Prime Minister Keir Starmer moved swiftly on Thursday night, launching a last-minute diplomatic effort to convince former US President Donald Trump that NATO and its European members are fully capable of protecting the Arctic—without the United States needing to take over Greenland.
The push came amid growing alarm in European capitals that the dispute could seriously fracture the NATO alliance.
Within the space of a single day, Sir Keir held conversations with Denmark’s Prime Minister, NATO’s Secretary General, and then spoke directly to Trump for the second time in just 48 hours. The urgency reflected the seriousness of the moment.
A Delicate Message to Washington
According to Downing Street, Starmer’s message to Trump was clear but carefully balanced.
He argued that European allies are already defending the Arctic region, while also acknowledging that more could still be done.
Both leaders reportedly discussed wider Euro-Atlantic security concerns and agreed on the need to counter what they described as increasingly aggressive Russian activity in the “High North.”
A UK government statement stressed that European allies had stepped up their efforts in recent months, but conceded there was room for further action to secure the region more effectively.
Denmark Draws a Firm Line
Earlier that day, Starmer spoke with Danish Prime Minister Mette Frederiksen, who has taken a notably hard stance on the issue.
She previously warned that if the US were ever to attack another NATO country militarily, “then everything stops”—a stark reminder of how serious the situation could become.
Despite the tension, both leaders agreed that NATO should increase its presence and readiness in the Arctic to protect shared Euro-Atlantic interests.
That position was echoed by NATO Secretary General Mark Rutte, who also agreed that stronger deterrence against Russia in the High North is now essential.
Trump’s Greenland Plan Sparks Alarm
At the centre of the storm is Donald Trump’s long-standing idea of acquiring Greenland, either by purchasing it or, more controversially, through military means.
The proposal has drawn criticism not only from political opponents but also from long-standing US allies across Europe.
Many critics believe Trump’s interest is driven by Greenland’s vast reserves of minerals and rare-earth elements, which are increasingly valuable in the global energy and technology race.
Others argue that the damage such a move could do to NATO far outweighs any strategic gain.
US Signals Preference for Purchase, Not Force
US Secretary of State Marco Rubio has attempted to ease some concerns by telling American lawmakers that the administration’s preference is to buy Greenland rather than use military force.
He has also avoided publicly discussing any military options, saying those conversations would take place privately with Danish officials during scheduled talks next week.
White House advisers are expected to use those crisis meetings to explore a peaceful path forward, with the stated aim of avoiding any escalation.
Greenland’s Complicated Status
Although Greenland governs its own domestic affairs, it remains part of the Kingdom of Denmark.
Its population of around 57,000 largely favours eventual independence from Copenhagen, adding another layer of complexity to the situation.
Greenland’s government has confirmed it will take part in the upcoming talks between Denmark and the US, signalling that decisions about the island’s future cannot be made without its involvement.
A Chilling Military Reality
Behind the diplomatic language lies a far more unsettling scenario.
Under Danish military rules dating back to 1952, Danish forces are legally required to respond immediately to any invasion—without waiting for orders.
In practical terms, that could mean Danish and US troops facing each other militarily, despite having worked side by side to protect Greenland for decades.
The mere possibility of such a clash has deeply worried European leaders.
Europe Closes Ranks as Macron Speaks Out
Across the continent, leaders have lined up behind Denmark.
French President Emmanuel Macron openly condemned what he called the “law of the strongest,” warning that the world is now seriously asking whether Greenland could be invaded.
Keir Starmer has reiterated the UK’s position in repeated calls with both Copenhagen and Washington, consistently stressing that NATO cooperation—not unilateral action—is the only viable way forward.
What Comes Next for NATO and Greenland?
With high-level talks scheduled and diplomatic lines buzzing, the coming weeks will be crucial.
The question now is whether the US, Denmark, and their allies can find a solution that strengthens Arctic security without tearing at the fabric of NATO—or whether Greenland will remain a flashpoint in an already unstable global landscape.
