Bet there’s loads of lovely oil under all the boring snow and dumb reindeer too…
Of course there is, Greenland is very mineral rich, which is why Diaper Don is so keen on encouraging the use of non-renewable resources, to increase climate warming, to melt the icecaps so that mining for all those wonderful minerals is easier, so that all his ultra rich industrial buddies will pay him billions and keep him in power so that they can keep making more money.
Simples.
And Don probably thinks he’ll get away with it because he’s got Putin and Xi to keep all the other nations who aren’t run by authoritarian Fascist despots busy.
Trying to follow the machinations of all these assholes is enough to drive one crazy if you let it.
