Realistic way to "liberate" Greenland and have it join the US

[Santander]

Greenland ought to be independent, not exchange one colonial power for another.

Greenland is independent, but under the diplomatic and military protection of Denmark. Precisely, in fact, to counter foreign aggression like described in this thread.

They'd probably turn down $1,000,000 USD in a heartbeat because our social services suck.

Health care services are primarily the responsibility of the government of Greenland. The health care system is obligated to deliver equal health care to all citizens regardless of their place of residence; all health care services are free – including the prescribed medicine.

OK I'll sweeten the pot. I'll throw in that every one of the 56,000 people that live in Greeland are eligible for Medicare.

I would find it tough to turn down a million dollars per person. That's a hell of a lot of money and would improve the life of the average greenlander by quite a lot.

This has to be trolling.
