ON THIN ICE: President Trump issues a firm warning to Denmark over Greenland, making it clear that the U.S. will remember if its request for "world protection" is rejected: "So we want a piece of ice for world protection, and they won't give it." "We've never asked for anything else and we could have kept that piece of land and we didn't sell. They have a choice. You can say yes, and we will be very appreciative — or you can say no and we will remember."
