Why Trump's plan to buy Greenland is not as stupid as the man who announced it. Actually, it's evil.
Greenland is a place that you do not want to be unless you are from there. The obvious problem is cold. If one has read Jared Diamond's Collapse, one knows that Greenland is one of the few places on Earth that Europeans failed to succeed in colonizing, and finally failed at even surviving in. The status of the 56,000 mostly indigenous people who live there as Danish Citizens of an autonomous region make it unique in the world. This why the world got a unique laugh when Donald Trump offered to buy it from Denmark. The Danes were perplexed.
