Are there any underlying security motives for the Trump administration wanting to acquire Greenland?

“The Greenland [acquisition] talk has roots in a real issue about the Northwest Passage. The receding sea ice, and the shipping lane that's been created up there because of that, brings the passage into contact with Greenland. And the point is, what are you going to do if the Russians— who cause all kinds of problems within those different, varied sovereignty claims – set up a base in northern Greenland now? Or even the Chinese? It is a real national security issue, one I would say is moderately critical, and I think the national security people understand what he's talking about. It's about maintaining control over the Northwest Passage.”
