As a dane, I can't help but wonder... Isn't this the deal we had with the US all along?
The previous agreement already gave the US permission to build military bases in Greenland, and they used to have many more bases, but the US chose to close down those bases themselves...
So isn't this basically the same as it already was, maybe with the benefit of it looking nice to Trumps voters that he didn't lose, because he got everything he wanted, eventhough he technically already had it?
