@Olivier5,
Since Trump said yesterday that buying Greenland isn’t "No. 1 on the burner", perhaps Denmark’s bid for the United States have no priority as well.
Trump says he is looking at the idea of the US buying Greenland – video
But seriously: "Denmark, essentially, owns it. We’re very good allies with Denmark, we protect Denmark like we protect large portions of the world. And so the concept came up and I said certainly, strategically it’s interesting. And we’d be interested."
Trump then suggested that Greenland was "hurting Denmark very badly" throwing out the figure that it cost the Danish government "$700 million".
Greenland has a diplomatic representation in Washington, DC (Inuuteq Holm Olsen is the Minister Plenipotentiary) since Greenland represents itself
externally in all areas over which they have taken over sole competence
from the Kingdom of Denmark (and that consist of Denmark, Greenland and the Faroe Islands).
There is no Faroese diplomatic representation in the USA, but only in Brussels, Copenhagen, London, Moscow and in Reykjavík - could be a nice deal as well!
