Trump, Denmark and Greenland leaders sign sweeping security pact at UN
At the United Nations, Donald Trump and Danish Prime Minister Mette Frederiksen signed a security agreement with Greenland officials that grants the United States permanent security authority over the territory.
The trilateral deal was concluded at the UN headquarters, with Trump describing it as an “Infinite Life” arrangement that gives Washington lasting control of Greenland’s security needs. Denmark’s Mette Frederiksen emphasized that the pact respects the Kingdom’s sovereignty and the Greenlandic people’s right to self-determination. Both sides presented the same document, highlighting divergent interpretations of its implications.
Why it matters
The deal could shift strategic control in the Arctic, affecting U.S., Danish, and Greenlandic interests.
