What are the odds of a nuclear war happening this century? And how close have we been to nuclear war in the past? Few academics focus on the probability of nuclear war, but many leading voices like former US Secretary of Defense, William Perry, argue that the threat of nuclear conflict is growing.

On this month's podcast, Ariel spoke with Seth Baum and Robert de Neufville from the Global Catastrophic Risk Institute (GCRI), who recently coauthored a report titled A Model for the Probability of Nuclear War. The report examines 60 historical incidents that could have escalated to nuclear war and presents a model for determining the odds are that we could have some type of nuclear war in the future.
