Donald Trump hinted he still wants to buy Greenland, a self-ruling territory of Denmark, saying that US ownership and control of the island is an “absolute necessity” for national security.

Since his first term, President-elect Donald Trump has insisted that the United States should purchase Greenland — to the bewilderment of aides asked to investigate such a possibility, and despite repeated denials by top officials in Greenland and Denmark, of which the island is an autonomous territory, that it would ever be for sale at any price.

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.
