Framing Questions: What is the future of the US nuclear deterrent from the National Laboratory context, near-, mid- and long-term? How does the role of the national laboratories in science and technology work to sustain the credibility of the nuclear deterrent? Discussion Proposal: This roundtable is proposed as a presentation/discussion with Los Alamos and Sandia National Laboratory staff that examines the role of the labs in sustaining a safe, secure, and effective nuclear deterrent for the United States and its allies. This roundtable will explore the role of the deterrent, what it does, and the importance of the deterrent to US national security policy. This discussion will also include discussion on the broader role of science and technology in policy-making and how the Laboratories help the nation address key national security issues.
