One of Donald Trump’s top aides, Stephen Miller, has declared that no country will fight the US over Greenland. In a CNN interview, Miller said, "nobody's going to fight the US over the future of Greenland." He called for Greenland to become part of the US to help protect NATO and Arctic interests. Miller questioned Denmark’s control over Greenland, saying, "By what right does Denmark assert control over Greenland? What is their basis of claiming Greenland as a colony of Denmark?" On Sunday, Trump repeated that the US "needs" Greenland, angering Danish Prime Minister Mette Frederiksen, who warned that a US attack would end NATO. In response, six European allies backed Denmark in a joint statement, saying "Greenland belongs to its people, and only Denmark and Greenland can decide on matters concerning their relations." The UK, France, Germany, Italy, Poland, Spain and Denmark stressed Arctic security must be ensured collectively by NATO, following the UN Charter’s principles of sovereignty and border inviolability. Miller insisted, "The US is the power of NATO. For the US to secure the Arctic region, to protect and defend NATO and NATO interests, obviously Greenland should be part of the US." The issue resurfaced after a US raid in Venezuela and Trump’s claims of US supremacy in the Western Hemisphere. Miller’s wife posted a photo of Greenland in US flag colors with the word "SOON" on social media. Trump sees Greenland as key to US security for its location and mineral wealth. The US recently appointed a special envoy to Greenland, prompting anger in Denmark. Greenland has 57,000 people and extensive self-government, but defense and foreign policy are Danish. Most Greenlanders want full independence, not US control.
