I live in Denmark and I can say that Europe and the Danes are completely delusional. Denmark gave Greenland home rule in 1979. Ie indipendence. The Greenland parliament do not need to ask Denmark for permission to secede and join USA. Historically, Denmark has treated the inuit similarly to how USA has treated their indians. Not good. The inuit are still treated as the weirdos up north. There's plenty living in Copenhagen. But they're not welcome in the regular Danish workforce. Alcoholism and social problems are rampant. While Greenlanders are proudly Danish. I doubt that Danish patriotism runs deep. Denmark certainly hasn't earned it.
Denmark is one of the last European countries where the carbon net zero goal isn't just something politicians say. It's actual policy. Denmark has promised to never tap Greenland for oil and seem to mean it. While Alaska is USA's richest state per capita. Greenland and Alaska are quite similar in that they sit on massive oil reserves and have tiny populations. My guess is that Trump has made the accurate observation that the Greenland inuit are being screwed over by the Danish government.
The stuff Trump is saying now.. it's just noise. The only realistic way Trump can take Greenland is to make an offer to the Greenland parliament that is better than the shit Denmark is offering them, and then let democracy happen. So that's obviously the way it will happen... if it will happen. No WW3. No NATO problem.
Trump is blundering around in the Western Hemisphere like a megalomaniac sociopath (sociopathic megalomaniac?). Trump doesn't have a sense of empathy and he sucks at deals that require any sense of symbiosis. So no, the US isn't providing Greenland anything they'll find great.
Worse yet, Greenland isn't about resources. It is about shutting the NW Passage off from Europe. The US doesn't need Greenland, we can always come up with some sort of arrangements on minerals or oil. Russia wants the US to control access to the NW Passage and keep it from Europe (because they lack the power to do so themselves), which requires the US having access to Greenland territory.
I still think Trump is a cunt. But thought there was some nuance missing from the general discussion on this. While Trump is a moron. He's not quite as moronic as people think.
He is much dumber than people think. We are currently in the 21st century. Energy, superconductors, rare earth elements, and access to clean water are the critical things moving into the future. Trump is wandering around like the Japanese Empire who needs to seize oil assets to make their imperialism possible.
