Editor’s note: In light of development at the NATO 2026 summit in Ankara, we are providing these essays as a collection.

In this collection, experts examine the legal, political, and security dimensions of U.S. policy towards Greenland, including with respect to U.S.-NATO relations, congressional oversight, and broader geopolitical implications.
