Why is President Donald Trump’s interest in Greenland a potential threat to NATO?
As President Donald Trump prepares to attend the World Economic Forum’s annual meeting in Davos, Switzerland, he fires a new message to NATO allies over Denmark’s determination to seize territory in Greenland, escalating tensions with Greenland and European leaders.
The escalating debate over the Arctic islands threatens to reignite a trade war with Europe and upend the North Atlantic Treaty Organization (NATO) alliance that has underpinned Western security for decades. President Trump is scheduled to arrive in the Swiss Alpine ski resort town on January 21 for meetings with the world’s business, government and cultural elite.
But ahead of that, in the early hours of January 20, Trump made a series of troll posts on Truth Social, taking aim at French President Emmanuel Macron and what he characterized as Britain’s “great stupidity” over its decision last year to cede the Chagos archipelago in the Indian Ocean to Mauritius, linking it to the Greenland issue.
Trump also posted a doctored image of European Commission President Ursula von der Leyen sitting in the Oval Office of the White House next to a map showing Greenland and Canada as US territories. He also posted another AI image of an American flag planted in Greenlandic soil next to a sign that reads “US TERRITORY. EST 2026.”
The onslaught of messages came as European Union leaders said they were discussing possible $108 billion worth of retaliatory tariffs on U.S. imports after President Trump announced over the weekend tariffs on imports from European allies that oppose his stance on Greenland, an autonomous territory of the Kingdom of Denmark. President Trump has said he will “take” Greenland for the United States, by force if necessary. Denmark is also a NATO ally.
In his post, President Trump shared a message that appeared to be from President Macron, saying, “I don’t understand what they are doing in Greenland.” French authorities did not immediately respond to a request to confirm the authenticity of the message. Reuters reported that it was genuine.
Greenland Prime Minister Jens Frederik Nielsen said in a Facebook post: “Greenland is a democratic society with the right to decide for itself. Recent statements from the United States, including the threat of tariffs, do not change that policy. We will not allow ourselves to be pressured. We remain committed to dialogue, respect, and international law.”
This follows a text message that President Trump sent to Norwegian Prime Minister Jonas Gare Stoer, in which he linked his desire to take control of Greenland to his failure to win the Nobel Peace Prize and said he was no longer thinking “purely about peace.”
In May, British Prime Minister Keir Starmer agreed to hand over the Chagos Islands to Mauritius, while retaining control of the joint Anglo-American military base on Diego Garcia, the largest island in the archipelago. At the time, Secretary of State Mark Rubio said President Trump “expressed his support for this monumental accomplishment.”
U.S. Treasury Secretary Scott Bessent, speaking at Davos, said he was confident European governments would not “escalate” tensions with the United States over its bid to buy Greenland. “This is ultimately going to be a very good thing for everyone,” Bessent told reporters on the sidelines of the World Economic Forum meeting.
