U.S. President Donald Trump says he is sending a U.S. Navy hospital ship to Greenland because people there are sick and lack care. On Sunday, Greenland and Denmark pushed back and praised their free public health systems. The dispute follows a rescue on Saturday, when Denmark’s Arctic command evacuated a U.S. submarine crew member near Nuuk for urgent treatment. Trump posted on Truth Social that a “hospital boat” was “on the way," even though both ships are at a shipyard in Alabama. The episode adds to growing tensions over Trump’s takeover talk.
