Why does Trump want Greenland and could he get it?

Description

Greenland's strategic location and resources could benefit the U.S. It lies along the shortest route from Europe to North America, vital for the U.S. ballistic missile warning system.

According to Ulrik Pram Gad, senior researcher and expert on Greenland, the idea of buying Greenland is based on a misunderstanding of international law and the principle of self-determination, which gives people the right to choose their own political status.
