America's Greenland

I have to disagree with you. I get President Trump is rude, and I wish he weren't, especially in dealing with allies. But he's not wrong about Greenland. It's sad that others are offended - but he's right about what it can be in the defense of the West - both US and Europe, militarily and economically. And he's point of view is easily defendable morally speaking.
You're right that he sees it in real estate terms, but that's a positive, not a net negative.
Secondly, your description of Alaskan natives and their rights has the truth on its head. They benefit from indigenous rights that a lot of tribal peoples have, as well as full US rights. Yet a fairly significant portion of them refuse to benefit from it, and become wards of the state. That's sad but it's a simple fact - and the rest of the population have lost their patience with victim grievance. It's nonsense.
If Greenlander's want their own country - they can certainly be allowed that - but the idea that 65,000 people that have no loyalty to or been responsible for others - get to veto actions necessary for the millions in the west - is absurd, morally as well. Finally, they would benefit immensely in a deal with the US. They turn down the opportunity at their peril.
