Donald Trump has, again, floated the notion that Greenland should be controlled by the United States. Greenland is, in fact, a territory of Denmark which is unlikely to just give it away. It is not clear whether Trump is serious.

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.

Greenland is not for sale, its elected leader said on Monday, responding to comments made by U.S. President-elect Donald Trump regarding the "ownership and control" of the vast Arctic island that has been part of Denmark for over 600 years.
