Trump’s Greenland Ultimatum: Tariffs Threat If Denied – Denmark & NATO Push Back

President Donald Trump intensifies his push for US control of Greenland in January 2026, warning of tariffs against countries that oppose the move. He cites national security needs in the Arctic amid rising Russian and Chinese influence, refusing to rule out stronger actions.

The autonomous Danish territory holds strategic importance with vast minerals and military positioning. Trump argues America must secure it to counter adversaries, echoing his long-standing interest in acquiring the island.

Trump’s Tariff Threats and Security Rationale

Trump states he may impose tariffs on allies not supporting US acquisition efforts. White House officials emphasize preventing Russia and China from expanding Arctic footholds, pointing to melting ice opening new routes and resources.

The president describes Greenland as vital for “international security,” suggesting a deal “should and will” happen. He floats purchase offers but links cooperation to trade penalties if resisted.

Denmark’s Firm Rejection

Danish Prime Minister Mette Frederiksen calls the pressure “unacceptable,” reaffirming Greenland is not for sale. She warns any US attack on the territory would end NATO, as it violates Article 5 mutual defense.

Greenland’s leaders echo: the island’s future belongs to its people. Protests erupt in Copenhagen and Nuuk, with thousands rallying against annexation threats.

NATO Secretary General stresses collective Arctic security without territorial changes. Analysts worry the standoff strains the alliance, diverting focus from Ukraine and playing into adversaries’ hands.
