'Absolute necessity': Trump sparks concerns after floating desire to control Panama Canal, Greenland

President-elect Donald Trump suggested on Wednesday that the U.S. could take control of Canada, Greenland and the Panama Canal—an unexpected Christmas Day message that has sparked concerns among world leaders in recent days as they scramble to prepare for Trump's second White House term.

In a Wednesday post on the platform Truth Social, Trump wished a "Merry Christmas to all," including to the "wonderful soldiers of China, who are lovingly, but illegally, operating the Panama Canal," before moving on to take aim at Canada and Greenland as well, which he suggested again could be better off under U.S. governance.
