Danish leader says kingdom can't negotiate sovereignty after Trump's Greenland about-turn

He said “additional discussions” on Greenland were being held concerning the Golden Dome missile defense program, a multilayered, $175 billion system that for the first time will put U.S. weapons in space. Trump offered few details, saying they were still being worked out.

Denmark insists on territorial integrity

Danish Prime Minister Mette Frederiksen said in a statement Thursday that security in the Arctic is a matter for all of NATO, and it is “good and natural” that it be discussed between the U.S. president and NATO Secretary General Mark Rutte. She said that she had spoken with Rutte “on an ongoing basis,” including before and after he met Trump in Davos.

She wrote that NATO is fully aware of the kingdom of Denmark's position that anything political can be negotiated on, including security, investment and economic issues — “but we cannot negotiate on our sovereignty.”

“I have been informed that this has not been the case,” she said, adding that only Denmark and Greenland can make decisions on issues concerning Denmark and Greenland.

Frederiksen said that Denmark wants to continue engaging in constructive dialogue with allies on how to strengthen security in the Arctic, including the U.S. Golden Dome program, “provided that this is done with respect for our territorial integrity.”

Asked in an interview with Fox News whether Greenland would remain part of the kingdom of Denmark under the framework deal Trump announced, Rutte replied that “that issue did not come up any more in my conversations tonight with the president.”

“He’s very much focused on what do we need to do to make sure that that huge Arctic region, where change is taking place at the moment, where the Chinese and Russians are more and more active, how we can protect it,” he said. “That was really the focus of our discussions.”

Welcome and skepticism over Trump's switch

On the streets of Copenhagen, some were skeptical about Trump’s switch.

“I think the man has said many things and done a lot of different things to what he says,” said Louise Pedersen, 22, who works with a startup company. “I have a hard time believing it. I think it’s terrifying that we stand here in 2026.”

She said it’s for Greenlanders to decide what happens with their land — “not Donald Trump.”

“I don’t really trust anything Mr. Trump is saying,” said Poul Bjoern Strand, 70, an advertising worker.

On the possibility of ceding territory, he said: “That’s not what the Greenlanders want, that’s not what the Danish people want, and ... I cannot believe that Danes are going to follow that.”

Chancellor Friedrich Merz of Germany, one of the European countries that had faced Trump's threat of tariffs over Greenland, underlined the need for European NATO allies to do more to secure the Arctic region and stressed that it is “a common trans-Atlantic interest.”

“We will protect Denmark, Greenland, the north from the threat posed by Russia,” he said at the World Economic Forum meeting in Davos, Switzerland. “We will uphold the principles on which the trans-Atlantic partnership is founded, namely sovereignty and territorial integrity.”

“We support talks between Denmark, Greenland (and) the United States on the basis of these principles,” aiming for closer cooperation, Merz said. “It is good news that we are making steps into that right direction. I welcome President Trump's remarks from last night — this is the right way to go.”
