President Donald Trump says that NATO should help the U.S. acquire Greenland and anything less than having the island in U.S. hands is unacceptable. His comments in a social media post Wednesday came hours before Vice President JD Vance was to host Danish and Greenlandic officials for talks. Trump argues that NATO should support the U.S. in acquiring Greenland to prevent Russian or Chinese influence. Greenland, a semiautonomous territory of NATO ally Denmark, is strategically important due to potential trade routes and mineral resources. Denmark and Greenland oppose U.S. control and residents of Greenland's capital say it's not for sale.
