The White House said on Tuesday: “The president and his team are discussing a range of options to pursue this important foreign policy goal, and of course, utilizing the US military is always an option at the Commander-in-Chief’s disposal.”
Nato is a trans-Atlantic military group where allies are expected to go to each other’s aid in case of external attacks.
On Tuesday, six European allies expressed support for Denmark.
“Greenland belongs to its people, and only Denmark and Greenland can decide on matters concerning their relations,” the leaders of the UK, France, Germany, Italy, Poland, Spain, and Denmark said in a joint statement.
Stressing they were as keen as the US in Arctic security, the European signatories of the joint statement said this must be achieved by Nato allies, including the US “collectively”.
They also called for “upholding the principles of the UN Charter, including sovereignty, territorial integrity and the inviolability of borders”.
