A newly revealed letter from Donald Trump to Norway’s prime minister has triggered sharp international concern after the former U.S. president linked a Nobel Peace Prize grievance to demands for “complete and total control of Greenland.” The message, disclosed on January 19, has raised questions about diplomacy, alliance norms, and respect for territorial sovereignty.
The letter, obtained and reported by Nick Schifrin of PBS News, was addressed to Jonas Gahr Støre. In it, Trump complained that Norway had not awarded him the Nobel Peace Prize and argued that this freed him from thinking “purely of peace,” allowing him instead to focus on what he described as U.S. national interests.
Trump went on to question Denmark’s sovereignty over Greenland, asserting—incorrectly—that there are no written documents confirming Danish control. He claimed that Denmark could not protect the territory from Russia or China and argued that the United States should assume full control for global security reasons. Greenland is an autonomous territory within the Kingdom of Denmark, a fact recognized under international law.
According to Schifrin, the letter was not treated as a private exchange. It was formally circulated to several European ambassadors, underscoring that the message represented an official communication rather than a personal aside. Diplomats say this detail significantly heightens the seriousness of the incident, as it places Trump’s remarks within the context of intergovernmental relations.
Foreign policy observers note that it is highly unusual for a sitting U.S. president to openly challenge the sovereignty of a NATO ally. Trump also referenced his record within NATO, claiming he had done more for the alliance than any individual since its founding and suggesting NATO now owed the United States reciprocal action.
The language used in the letter has alarmed European officials, particularly Trump’s framing of Greenland as essential to global security unless it falls under U.S. control. Denmark considers Greenland an integral part of its sovereign territory, and officials have repeatedly rejected any suggestion of transferring control.
Analysts warn that the letter is likely to intensify existing tensions surrounding Greenland’s strategic importance in the Arctic, a region increasingly shaped by geopolitical competition. By tying personal grievances to national security claims and bypassing diplomatic norms, critics argue the message risks undermining trust among allies.
As the contents of the Trump Greenland letter continue to circulate among European governments, diplomats fear it could complicate transatlantic relations and reignite debates over U.S. foreign policy conduct toward long-standing partners.
