Greenland actually makes a lot of sense. I think if every citizen there was offered $5million they’d vote yes. And it’s entirely reasonable from the USA perspective as it’s not that much overall for the US.
Probably wouldn’t make a state but treat like Puerto Rico where they continue to self govern and citizens can freely move to the USA as they’d have USA passports.
For USA very strategic naval passages and mineral extraction.
It’s not that crazy really and I think there’s a deal that’s mutually beneficial where everyone wins and is better off long term.
