Denmark, Greenland, and the United States are set to sign a security deal on Tuesday at the UN General Assembly in New York, which will allow for an expanded U.S. military presence in Greenland while placing Arctic responsibility under NATO's jurisdiction. The agreement, expected to include sites like Narsarsuaq and Mestersvig, follows pressure from former President Trump who previously pushed for greater control over Greenland. Danish officials stress that the deal respects Greenland’s sovereignty and strengthens NATO’s role in Arctic security.

Denmark and Greenland say deal will benefit Arctic island and respect its sovereignty
Denmark, Greenland and the U.S. are to sign a deal on Greenland's security on Tuesday, an agreement Denmark says will put Arctic security under NATO's watch rather than leaving it solely to Washington and Copenhagen.

threats → peak → pressure
The agreement "will be in a form where responsibility for security in the Arctic is not only Danish or American," Danish Foreign Minister Lars Løkke Rasmussen told national broadcaster TV2 on Sunday.
asserted
Rasmussen → tell → Sunday
He said that, to a large extent, "it would be NATO that looks after the Arctic."
asserted
that → say → Arctic
It remained unclear whether the deal amends an existing 1951 defence agreement that is the legal basis for the U.S. presence in Greenland.

It appears that we are now using this crisis to try to strengthen NATO's cohesion through Greenland," said Ulrik Pram Gad, a researcher at the Danish Institute for International Studies (DIIS).

U.S. → build → DIIS
In 1946, then-U.S. president Harry Truman sought to buy the island as a strategic asset for $100 million US in gold, but Copenhagen declined to sell.
asserted
Copenhagen → seek → gold
Instead, a new agreement was signed in 1951 that gave the U.S. military extensive rights in Greenland but was tied to the existence of NATO.
asserted
that → sign → NATO
"I don't think Denmark and Greenland will sign if the same NATO clause isn't included," said Gad.

A NATO spokesperson said on Saturday that the alliance welcomed the new agreement, which would "help advance security, stability and co-operation in this vital region."
Rasmussen, who travelled to New York overnight, declined to discuss the contents of the agreement.
"But we have said from the start that we are open to accommodating the United States' legitimate security interests," he told Danish news agency Ritzau on Monday.

Trump says deal struck to boost U.S. military presence in Greenland
Greenland, Denmark say deal with U.S. will not cede sovereignty
Trump said in a social media post on Friday the agreement gave the U.S. "permanent control over security, and all other needs, in Greenland," and that no U.S. adversary could have a base or military presence there without Washington's written approval.
Denmark has not responded to Trump's assertion, though Copenhagen earlier acknowledged it underinvested in Greenland's defence for decades and has pledged to expand its military presence on the island, including more NATO troops.
Greenland's government has sought to reassure the public about the deal.
Erik Jensen, an opposition lawmaker in Greenland, wrote on social media that he had read the draft agreement.
uncertain
he → say → agreement
"I feel reassured and am not worried," he said, adding that the island's foreign minister was handling the work well.
