White House deputy chief of staff Stephen Miller said that "nobody's going to fight the United States militarily" over Greenland as President Trump repeated his interest in making the semi-autonomous Danish territory a U.S. territory.

Milleron Monday reaffirmed the “formal position of the U.S. government” that “Greenland should be part of the United States” in an interview with CNN, The Hill news outlet reported.

“The United States should have Greenland as part of the United States. There’s no need to even think or talk about this in the context that you’re asking, of a military operation,” Miller told CNN’s Jake Tapper, who repeatedly asked if Miller would rule out military action against Greenland.

“Nobody’s going to fight the United States militarily over the future of Greenland,” Miller added.

“The real question is, by what right does Denmark assert control over Greenland? What is the basis of their territorial claim? What is their basis of having Greenland as a colony of Denmark?” he asked.

“The United States is the power of NATO. For the United States to secure the Arctic region to protect and defend NATO and NATO interests, obviously, Greenland should be part of the United States,” Miller continued. “And so that’s a conversation that we’re going to have, as a country.”

Trump told reporters aboard Air Force One on Sunday, "We need Greenland from a national security situation. It's so strategic. Right now, Greenland is covered with Russian and Chinese ships all over the place. We need Greenland from the standpoint of national security. And Denmark is not gonna be able to do it, I can tell you."

Danish Prime Minister Mette Frederiksen said Monday regarding Trump's remarks, “I believe one should take the American president seriously when he says that he wants Greenland,” according to a translation from Bloomberg.

“But I will also make it clear that if the U.S. chooses to attack another NATO country militarily, then everything stops, including NATO and thus the security that has been established since the end of the Second World War,” she continued.

Late Sunday, Greenland Prime Minister Jens-Frederik Nielsen said, according to Reuters, "Threats, pressure, and talk of annexation have no place between friends. Enough is enough," adding, "No more fantasies about annexation."
