A Greenland security pact is set for next week’s UN
BBC and Al Jazeera both reported on 18 September 2026 that Denmark, Greenland and the United States described a security pact to be signed at the United Nations General Assembly the following week, still needing votes in Nuuk and Copenhagen. Donald Trump wrote on Truth Social of lasting US control and a bar on adversary bases without written US approval. Mette Frederiksen said the text recognises the Kingdom’s sovereignty and Greenlandic self-determination.

Signed next week, if parliaments agree
The BBC and Al Jazeera, on 18 September 2026, both placed the same calendar on the table: Denmark and Greenland say a pact with the United States is due to be signed during the next United Nations General Assembly session. Al Jazeera added that Nuuk and Copenhagen still have to vote. The BBC quoted Danish Prime Minister Mette Frederiksen saying Arctic and North Atlantic security would be stronger, and that legislative steps remain before the text can enter into force. Greenland’s Jens-Frederik Nielsen, in both accounts, welcomed a deal he said strengthens the territory’s security. That is a planned signing, not a treaty already in force.[1], [2]
What Trump posted
The BBC reported that Trump wrote on Truth Social that the United States, Denmark and Greenland had reached an agreement, claiming lasting US control over security and all other needs, no cost to Washington, and a ban on any US adversary keeping a base, a military presence or making sensitive investments without written US approval. Al Jazeera’s reading of the same post stressed a lasting US ability to do what is necessary in Greenland and a significant US military footprint. Those are his words on a social network, not the Danish joint statement’s wording.[1], [2]
Sovereignty language in Copenhagen
Frederiksen, in the BBC account and again in Al Jazeera, said the agreement recognises the sovereignty and territorial integrity of the Kingdom and the Greenlandic people’s right to self-determination. Nielsen’s welcome sits beside that clause. Neither dispatch says the parliaments have already voted, and neither treats Trump’s lasting-control phrase as the Danish legal text. The story on 18 September is an announced pact and a fight over how to describe it, not a completed transfer of title.[1], [2]
