U.S. President Donald Trump said on Monday that the United States will look into the issue of annexing Greenland during this week's World Economic Forum in Davos, noting that Denmark cannot protect the island. 'They are great people... I know the leaders, they are very nice people, but they are not going to be able to do it,' Trump told reporters in Florida late on Monday. 'Denmark can't protect it. It has to be done.'
