President Donald Trump warned Friday that he may impose tariffs on countries opposing U.S. acquisition of Greenland, triggering European military deployments and bipartisan congressional resistance amid a deepening diplomatic standoff.
Tariff warning escalates tensions
Trump issued the threat during a White House roundtable, citing the importance of the national security of Greenland. The statement followed failed talks with Danish and Greenlandic officials, where no breakthrough occurred.
European military show of force
Germany, Sweden, France, Norway, the Netherlands, and Finland deployed troops for Operation Arctic Endurance, a Danish-led exercise. French President Emmanuel Macron confirmed units en route, while Armed Forces Minister Alice Rufo emphasized defending sovereignty against all parties, including the U.S.
Diplomatic talks stall
Danish Foreign Minister Lars Løkke Rasmussen declared irreconcilable differences over territorial integrity after a White House meeting with Vice President JD Vance and Secretary of State Marco Rubio. Both sides agreed only to form a high-level working group, but Trump insists on full U.S. control and has not ruled out military action.
Bipartisan delegation in Copenhagen
An 11-member U.S. congressional group, including Republican Senators Lisa Murkowski and Thom Tillis plus Democrats like Dick Durbin, met Danish Prime Minister Mette Frederiksen. They raised the Greenlandic flag at parliament in solidarity. Senators Shaheen and Murkowski introduced the NATO Unity Protection Act to block U.S. actions against allied territories.
White House remains defiant
Press Secretary Karoline Leavitt dismissed European troop movements as irrelevant to Trump’s objectives. The crisis underscores transatlantic rifts over Arctic strategy.
