And...then?
- Greenland still belongs to Denmark even if you give 99999999 gazillion to each Greenlander
- I don't think anyone in Greenland is dumb enough to sell out their country for 10k to then live in a country where you will pay out of your ass in taxes, handing those 10k right back to the IRS in 5 years tops.
- Greenlanders would have to call themselves "Americans" henceforth, which is considered an insult and lower class of civilization world-wide.
There is a shipping route opening up that would enable Asian-Europen-American trade via a about 2/3 shorter route than currently possible. It would make any route through the Suez canals or around Africa pointless. This might not sound important right now, but it would fundamentally change the fortunes of countries and reshape the world.
