Jens-Frederik Nielsen has pushed back against the US president's plan to annex the Danish autonomous territory

Newly elected Prime Minister Jens-Frederik Nielsen has urged the people of Greenland to unite and make it clear to US President Donald Trump that Washington will never take control of the island, stating that the Arctic territory's future belongs solely to its residents.

Trump renewed his claim to Greenland over the weekend, telling NBC News that Washington will "100% get" the island. He issued what appeared to be a veiled threat, saying there was a "good possibility that we could do it without military force," but adding that he would not "take anything off the table."

In a Facebook post on Sunday, Nielsen called for a calm but firm response to growing US pressure.

"We must not act out of fear. We must respond with peace, dignity, and unity," he wrote.

"President Trump says the United States is 'getting Greenland.' Let me make this clear: The US is not getting that," Nielsen said.

"We do not belong to anyone else. We determine our own future," he reiterated. "And it is through these values that we must clearly, clearly, and calmly show the American president that Greenland is ours. It was like that yesterday. That's how it is today. And that's how it will be in the future."

Nielsen, the leader of the Demokraatit party, was elected earlier this month in a surprise victory. His platform focused on protecting Greenland's autonomy, reducing dependence on Denmark, and encouraging international investment without relinquishing control over local resources.

Tensions escalated following a visit last week by US Vice President J.D. Vance and his wife to the Arctic island. Speaking at Thule Air Base, Vance claimed Denmark had "largely failed the people of Greenland," and argued the territory would be "a lot better coming under the United States' security umbrella."

Trump first floated the idea of acquiring Greenland in 2019 and has revived the proposal since returning to office. His administration describes the island as a strategic asset, citing its location and untapped natural resources.

Russian President Vladimir Putin, outlining Moscow's own Arctic strategy last week, warned that US annexation plans date back to the 1860s and should not be dismissed as "extravagant talk."
