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.

President-elect Donald Trump’s tough talk about Greenland and the Panama Canal shows that he’s most comfortable playing offense, even if nothing much comes of it.
