Arctic Sovereignty and Security: The U.S., Greenland, and Transatlantic Concerns

Copenhagen, Denmark. 17 th Jan. 2026.

Webinar

In January, President Trump reignited global attention on Greenland by publicly pushing for U.S. control of the semiautonomous Danish territory as part of the administration's framing of Greenland's strategic importance in countering Russia and China. The U.S. government threatened to use military force and impose tariffs on eight European NATO allies in response to their opposition, including France, Germany, and the U.K. These developments prompted formal Arctic security talks between U.S., Danish, and Greenlandic officials, even as Copenhagen, Nuuk, and other European capitals uniformly reject any transfer of sovereignty, underscoring tensions within longstanding defense partnerships.

The Pacific Council invites you to dial in on Thursday, March 19, at 10 am PT to explore these recent developments and discuss their broader implications for Greenlandic national security and the United States' diplomatic relations within Europe. Members will hear from Dr. Esther Brimmer, the James H. Binger Senior Fellow in global governance at the Council on Foreign Relations, and Dr. Justina Budginaite-Froehly, a Nonresident Senior Fellow of the Europe Center and the Transatlantic Security Initiative within the Atlantic Council’s Scowcroft Center for Strategy and Security.
