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 named Miami-Dade County Commissioner Kevin Marino Cabrera as his choice for the post after suggesting that the US should take control of the Panama Canal – a proposal he first floated over the weekend while claiming that Panama is “ripping off” American ships that pass through the waterway.
