BRUSSELS — President Donald Trump has revived his ambitions to incorporate Greenland into US territory citing national security, prompting European leaders to voice support for Denmark.

The US president has appointed Governor of Louisiana, Jeff Landry, as the new US special envoy for Greenland with the stated objective of “integrating Greenland into the United States” and repeated the US needs the territory for its national security.

His comments have been taken seriously by EU heads of state and government, who are presenting a united front against what they describe as American expansionist ambitions towards the autonomous territory, which is part of the Kingdom of Denmark.

France's President Emmanuel Macron and his Minister for Europe and Foreign Affairs, Jean-Noël Barrot, both responded to the announcement by reaffirming their support for the integrity of Denmark's territory.

"Greenland belongs to its people. Denmark stands as its guarantor. I join my voice to that of Europeans in expressing our full solidarity," Macron said.

On Tuesday, Trump told reporters the United States "needs Greenland for national security, not for minerals or oil, but national security. And if you take a look at Greenland, there are Russian and Chinese ships all over the place. So, we need this for protection."

He also chastized Denmark for what he described neglecting the territory, "they have spent no money, they have no military protection, they say Denmark arrived there 300 years ago with boats - we were there with boats too, I'm sure. We'll have to work it all out."

Adding to the European voices pushing back on the US ambitions and the criticism of Denmark, Commission Ursula von der Leyen insisted that “territorial integrity and sovereignty are fundamental principles of international law”. Despite the tone coming out of Washington, she appeared to refer to the US as an ally in arctic security.

Spanish Prime Minister Pedro Sánchez echoed those remarks. "Respecting sovereignty and territorial integrity is central to the EU and to all nations of the world," he wrote on X. "Security in the Arctic is a priority in which we seek to work with allies and partners."

The US and Denmark are part of NATO, which is supposed to ensure mutual defence in the event of aggression against one of its members. That principle has never been tested by conflict between members of the alliance if one were to seize territory from another.

NATO Secretary General Mark Rutte has so far remained silent on the issue. During a press conference with Trump in the White House's Oval Office in March, he also chose not to comment after a question from a journalist.

"When it comes to Greenland, if it joins the US or not, I will leave that outside of me in this discussion because I don't want to drag NATO into that," he said. — Agencies
