Odds and Ends

I could see the purchase initially being planned to avoid issues with stability. Denmark could have decided to just toss the Americans out if the USSR had been able to tempt them to join their side. Trying to strong arm the purchase would probably have guaranteed them to be tossed, so it didn't need to be pursued seriously as the alliances gave them access.
However, nowadays Trump doesn't care much for the alliances, but he would still need the Greenland bases for early warning, so I imagine that is why the purchase is coming up again.
