U.S. President Donald Trump has escalated his campaign for American control of Greenland, threatening on January 16 to impose tariffs on countries that do not support his plan. The move has drawn sharp reactions from European allies, with Denmark’s defense minister characterizing the situation as “grave” .
Trump’s Tariff Threat and Justification
Speaking at a White House roundtable on rural healthcare, President Trump explicitly linked his “Greenland plan” to trade policy for the first time. He stated that he might levy tariffs on nations opposing U.S. control of the autonomous Danish territory, citing national security concerns . “I may put a tariff on countries if they don’t go along with Greenland, because we need Greenland for national security,” Trump said, comparing the tactic to previous threats against European pharmaceutical companies . This stance reiterates his long-held position that Greenland’s strategic location in the Arctic is vital to U.S. interests .
International and Domestic Reactions
The threat has intensified diplomatic tensions within NATO and prompted both condemnation and concern.
- Danish and European Response: Danish Defense Minister Trine Bramsen described Trump’s remarks as highlighting the “severity of the situation” . In a show of solidarity with Denmark, several European nations, including France, Germany, and Norway, have dispatched small numbers of military personnel to Greenland. However, European officials have acknowledged that these deployments are largely symbolic and unlikely to deter a potential U.S. action . Austrian Chancellor described the situation as evidence that Europe must take control of its own security .
- Opposition Within the U.S.: A bipartisan delegation of U.S. lawmakers visiting Copenhagen signaled opposition to the administration’s plan. Senator Lisa Murkowski (R-Alaska) emphasized that Greenland should be viewed as an ally, not an asset, and cited polling indicating that approximately 75% of Americans oppose the acquisition of Greenland . This highlights a growing rift between the Trump administration and Congress on the issue .
- Local Sentiment in Greenland: The push for U.S. control has been met with firm resistance from Greenlandic and Danish leaders. Greenland’s Prime Minister has repeatedly stated that the island is “not for sale,” and a previous poll showed 85% of Greenland’s residents oppose becoming part of the United States . A Greenlandic politician involved in the talks accused the U.S. of being the source of current threats .
Background and Strategic Stakes
President Trump’s interest in Greenland dates back to his first term, but efforts have intensified since his return to office in 2025 . He has appointed a special envoy for Greenland, Jeff Landry, who announced plans to visit the island in March to negotiate a deal . The island’s significance stems from its vast untapped mineral resources, including rare earth elements, and its crucial geographic position for Arctic military and economic competition . While the U.S. and Denmark agreed to establish a working group after recent talks, a “fundamental disagreement” remains, with the White House focused on “obtaining” the island and Denmark insisting on respecting its sovereignty .
The confrontation underscores a deepening transatlantic rift and raises questions about the future of international norms regarding territorial sovereignty .
