A group of European countries, led by the U.K. and Germany, is discussing plans for a military presence in Greenland to show U.S. President Donald Trump that the continent is serious about Arctic security and to try to tamp down American threats to take over the self-ruling Danish territory.

Germany will propose setting up a joint NATO mission to protect the Arctic region, according to people familiar with the plans. U.K. Prime Minister Keir Starmer has separately urged allies to step up their security presence in the High North and recently reached out to leaders including French President Emmanuel Macron and German Chancellor Friedrich Merz to discuss the issue.

The U.S. raid to capture the leader of Venezuela this month, as well as heightened rhetoric from the Trump administration on possibly using military force to control Greenland, has forced European leaders to quickly cobble together a strategy. They want to show that Europe and the North Atlantic Treaty Organization have the region’s security under control, as they try to undercut Trump’s argument for taking over Greenland, said the people, who spoke on the condition of anonymity.

German Foreign Minister Johann Wadephul will meet with U.S. Secretary of State Marco Rubio this week, when he’ll address the issue of Greenland and what role NATO can play in the region’s stability.

“Because security in the Arctic is becoming increasingly important, I also want to discuss on my trip how we can best bear this responsibility in NATO — in view of old and new rivalries in the region by Russia and China — together,” Wadephul said in a statement on Sunday. “We want to discuss this together in NATO.”
