‘Greenland belongs to its people’: European leaders unite over Trump’s threats to annex territory

European leaders on Tuesday issued a joint statement to push back against U.S. President Donald Trump’s renewed interest in Greenland, saying security in the Arctic must be achieved collectively.

“The Kingdom of Denmark – including Greenland – is part of NATO,” the statement said, according to a letter published by Denmark’s Prime Minister’s Office on X.

“Security in the Arctic must therefore be achieved collectively, in conjunction with NATO allies including the United States, by upholding the principles of the UN Charter, including sovereignty, territorial integrity and the inviolability of borders. These are universal principles, and we will not stop defending them,” they continued.

“Greenland belongs to its people. It is for Denmark and Greenland, and them only, to decide on matters concerning Denmark and Greenland.”

The letter was signed by Danish Prime Minister Mette Frederiksen, French President Emmanuel Macron, German Chancellor Friedrich Merz, British Prime Minister Keir Starmer, as well as the leaders of Italy, Spain and Poland.

The coordinated message, which also described the U.S. as “an essential partner” in the push for Arctic security, comes as Trump once again sets his sights on the vast, mineral-rich and sparsely populated territory.

The U.S. president, who has long advocated for control over the self-governing Danish territory, told NBC News on Monday that he was “very serious” with his intent to acquire Greenland. Trump also said he had “no timeline” for doing so, however.

Alarm bells have been ringing in Denmark, which is responsible for the defense of Greenland, given that Trump’s remarks follow Washington’s major military operation in Venezuela.
