Denmark doesn't own Greenland so is not in a position to sell it. Denmark is together with Greenland (and the Faroe Islands) in a union, kind of like England and Scotland is in a union. The union is sometimes called the Kingdom of Denmark and have a shared royal crown, and obviously Denmark is the dominant part having 100 times the population of Greenland. But in theory they are equal parties. At the time the offer was made though, Greenlandic home rule was not established yet, so it was basically a province or colony of Denmark. Native population were forcibly displaced (by Danish authorities) to make space for the American Thule Air Base, so I'm not sure the Danish at the time were morally superior in their treatment of the native population compared to the US. In the post-war the strategy was basically to treat Greenland as a Danish province and turn the Inuit into Danes - one of the approaches was to forcibly take Inuit children from their parents and let them grow up in Denmark. In the 1970'ies the strategy was changed to give Greenland partial independence.
