Strategic early-warning and space surveillance facility

President Trump reversed his tariff threats and ruled out military force on January 21 after announcing a "framework" with NATO Secretary-General Mark Rutte. The framework covers Arctic security cooperation, U.S. access to Greenland's rare earth minerals (1.5 million metric tons—the world's eighth-largest reserves), and Trump's "Golden Dome" missile defense system ($175-831 billion shield against hypersonic threats).
