Artificial intelligence is reshaping the threat landscape for weapons of mass destruction in ways that existing arms control frameworks were never designed to address. On Thursday, November 19 at 11:30 am PT, the Pacific Council is hosting a webinar to examine the governance challenge at the heart of these shifts and explore how governments and industry should regulate AI models whose dual-use potential extends to catastrophic harm. Attendees will hear from Erin D. Dumbacher, Stanton Nuclear Security Senior Fellow and Director of the Defense and National Security Program, Council on Foreign Relations, and Dr. Stephen Herzog, Professor of the Practice, International and Global Studies; Director, Center for Nonproliferation Studies, Vermont Office, Middlebury College.
