The president-elect is renewing calls he made during his first term for the U.S. to buy Greenland, the ice-covered semi-autonomous Danish territory, and mostly Inuit

President-elect Donald Trump appears to be entertaining an American territorial expansion that, if he’s serious, would rival the Louisiana Purchase or the deal that netted Alaska from Russia.

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.
