Stephen I. Schwartz, a nonresident senior fellow at the Bulletin of the Atomic Scientists – and a virtual encyclopedia of all things related to the nuclear football – takes us back to the events of January 6. Schwartz talks about how the situation could have escalated if the “football” had been captured by the rioters. Early Warning features Sam A. Winter-Levy and Alasdair Phillips-Robins. And we answer a listener’s question about companies manufacturing nuclear weapons.
