This brief is the first in the CSIS Project on Nuclear Issues (PONI) Deep Dive Debrief that explores emerging or contentious nuclear challenges. These briefs are based on a series of “deep dive” workshops convened by PONI that bring together next generation technical, operational, and policy experts from across the nuclear community to debate and discuss these nuclear challenges. This brief reflects discussion and insights from a deep dive workshop convened by PONI on May 1, 2019, at U.S. Strategic Command (STRATCOM). The brief focuses on the emerging political, informational, and fiscal risks to the U.S. nuclear command, control, and communications (NC3) architecture. Collectively, these non-technical risks pose challenges to the resiliency, durability, and reliability of NC3. Read the full brief on CSIS.org.
