Denmark says NATO shares responsibility for Arctic security under Greenland deal

• Denmark, Greenland and the US will sign a security deal on Sept 22, placing Arctic security under NATO's responsibility instead of solely US or Danish control.
• The agreement aims to promote security, stability and cooperation in the Arctic, with Denmark acknowledging the need to strengthen its military presence on Greenland.
• President Trump claims the deal grants the US "permanent control" over Greenland's security, but Denmark and Greenland emphasise respect for sovereignty and have not confirmed this claim.

COPENHAGEN – Denmark, Greenland and the United States are set to sign a deal on Greenland's security on Sept 22, an agreement Denmark says will put Arctic security under NATO’s watch rather than leaving it solely to Washington and Copenhagen.

The agreement, expected to be signed at the UN General Assembly in New York on Sept 22, has not been made public, though US President Donald Trump says it grants the US “permanent control”.

Denmark and Greenland have not commented on Trump’s claim but said the deal will benefit the Arctic island and respect its sovereignty.

The deal follows months of pressure from Trump, who has said the United States should control Greenland and at times refused to rule out using military or economic force to acquire the semi-autonomous Danish territory.

His threats, which peaked in January, triggered a diplomatic crisis within NATO and pushed Denmark and Greenland into negotiations with Washington aimed at defusing the pressure.

“It (the agreement) will be in a form where responsibility for security in the Arctic is not only Danish or American,” Danish Foreign Minister Lars Rasmussen told national broadcaster TV2 on Sept 20.

He added that to a large extent “it would be NATO that looks after the Arctic”.

Promoting ‘security, stability and cooperation’

A NATO spokesperson said on Sept 19 that the alliance welcomed the agreement, which would “help advance security, stability and cooperation 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,” Rasmussen told Danish news agency Ritzau on Sept 20.

Trump said in a post on Truth Social on Sept 18 the agreement gives the United States “permanent control over security, and all other needs, in Greenland,” and that no US adversary could have a base or military presence there without Washington's written approval.

Denmark has not responded to Trump’s claim, though Copenhagen has 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.

Key details have not been made public, including whether the deal amends the 1951 defence agreement that is the legal basis for the US presence in Greenland.

Greenland’s government has sought to reassure the public about the deal.

Erik Jensen, an opposition lawmaker in Greenland, wrote on Facebook that he had read the draft agreement.

“I feel reassured and am not worried,” he said, adding that the island's foreign minister was handling the work well. REUTERS
