A controversial letter written by Donald Trump to Norway’s prime minister has ignited fresh tensions among NATO allies, after the former U.S. president linked a Nobel Peace Prize grievance to a demand for “complete and total control of Greenland.” The letter, revealed on Sunday evening, raises serious questions about diplomacy, sovereignty, and alliance relations.
The letter was made public by Nick Schifrin, who reported that Trump addressed the message to Jonas Gahr Støre. According to Schifrin, the correspondence was also circulated to several European ambassadors, indicating it was intended as an official communication rather than a private exchange.
In the letter, Trump argues that not receiving the Nobel Peace Prize released him from any obligation to think “purely of peace.” He claims this shift allows him to focus solely on what he describes as the interests of the United States. Trump then questions Denmark’s sovereignty over Greenland, asserting—incorrectly—that there are no written documents establishing Danish control over the territory.
Trump goes further by declaring that Denmark cannot adequately protect Greenland from geopolitical rivals such as Russia or China. He claims the world would remain unsafe unless the United States obtained “complete and total control of Greenland,” using language that analysts describe as unusually maximalist for diplomatic correspondence between allied nations.
The letter also invokes NATO, with Trump stating that he has done more for the alliance than any individual since its founding and suggesting that NATO now “should do something for the United States.” Observers note that explicitly questioning the territorial sovereignty of a NATO ally represents a sharp departure from conventional alliance norms.
Denmark considers Greenland an integral part of its sovereign territory, despite the island’s autonomous status. Trump’s assertions are widely viewed as historically inaccurate and legally unfounded, as Denmark’s sovereignty over Greenland is recognized under international law and formal treaties.
The fact that the letter was shared beyond Norway’s prime minister to multiple European diplomats has amplified concern across Europe. Analysts say the move signals an intentional effort to apply pressure publicly rather than resolve disputes through established diplomatic channels.
Trump’s remarks are expected to further escalate tensions surrounding Greenland, a strategically important Arctic territory that has become increasingly significant amid rising global competition in the region. While Trump has previously expressed interest in Greenland, the explicit demand for total control and the linkage to a personal Nobel Peace Prize grievance mark a notable escalation.
Diplomatic experts warn that such rhetoric risks straining transatlantic relations at a time when NATO unity is already under pressure from global security challenges. They add that the episode underscores how personal grievances, when embedded in official communications, can have far-reaching geopolitical consequences.
