Trump wants to take Greenland: Four ways this saga could go

In recent weeks, US President-elect Donald Trump has shown renewed interest in taking control of Greenland, a largely autonomous territory of Denmark in the Arctic and the world's largest island.

He first indicated an intention to buy Greenland in 2019, during his first term as president, but this week he went further, refusing to rule out economic or military force to take control of it.

Danish and European officials have responded negatively, saying Greenland is not for sale and its territorial integrity must be preserved.
