In this episode of Intelligence Matters, host Michael Morell speaks with Brian Morra, former Air Force intelligence officer and author of "The Able Archers," a novel based on the true story of a narrowly avoided nuclear confrontation between the U.S. and the Soviet Union in 1983. Morra details the key players and events that brought the two global superpowers to the brink of conflict - and what high-risk interventions were required to avert cataclysm. Morra explains how his book - and experience in 1983 - might have meaning for the Russia-led war in Ukraine today.
