U.S. President Donald J. Trump has called for decisive action regarding Greenland, accusing Denmark of failing for decades to address Russian security threats in the Arctic. In a post on his Truth Social platform, Trump wrote that NATO had warned Denmark for 20 years about Greenland’s strategic vulnerability, but that Copenhagen had “been unable to do anything about it,” adding, “Now it is time, and it will be done.”
Trump’s comments have prompted a strong response from key European allies. In a joint statement dated January 18, 2026, Denmark, Finland, France, Germany, the Netherlands, Norway, Sweden, and the United Kingdom reaffirmed support for Denmark and Greenland, stressing that Arctic security efforts must respect sovereignty and international norms. The statement warned that economic pressures or threats could undermine transatlantic relations and urged dialogue based on cooperation.
Greenland, an autonomous territory within the Kingdom of Denmark, has long been strategically important due to its location and natural resources. Analysts say Trump’s renewed remarks may heighten diplomatic tensions as NATO members balance Arctic security concerns with respect for national sovereignty.
