The United States, due in large part to Donald Trump’s renewed ambition to acquire Greenland, has this year dominated discussions on Arctic geopolitics. A timely new book, America in the Arctic: Foreign Policy and Competition in the Melting North (Columbia University Press 2025), analyses the long-term evolution of U.S. Arctic engagement across an array of issue areas. The book’s authorMary Thompson-Jones, a retired diplomat with the U.S. State Department and currently Professor of National Security Affairs at the U.S. Naval War College, joins the podcast to share her wide-ranging insights into the formation and future directions of U.S. policy in the Arctic, including topics such as climate change and science diplomacy, the Arctic as a theater for strategic competition, the procurement of icebreakers, and the increasingly important role of the U.S. Arctic gateway states of Alaska and Maine.
