Where is Greenland and why would Trump want to control it?

Greenland is located to the northeast of Canada and is largely covered by the Greenland Ice Sheet. The largest island in the world, but home to only around 60,000 people, it is a semi-autonomous territory of the Kingdom of Denmark, with its own elected government.

Its location between the U.S., Russia and Europe makes it strategic for both economic and defense purposes — especially as melting sea ice has opened up new shipping routes through the Arctic.

It is also the location of the northernmost U.S. military base.
