President-elect Donald Trump took aim at Canada, Greenland and the Panama Canal in a series of Christmas Day social media posts that suggested the United States could take control of all three.

At first, he joked about Canada being an additional US state. Since, he has threatened to take back control of the Panama Canal. He also reiterated a desire from his first term to own the autonomous Danish territory of Greenland, which is not for sale.

Trump again having designs on Greenland comes after the President-elect suggested that the U.S. could retake control of the Panama Canal.
