Joe Cirincione became only the second president of Ploughshares Fund following the passing of its founding president, Sally Lilienthal. Cirincione's career spans over four decades as a foreign policy analyst, national security staffer in Congress, and a frequent expert commentator in print and on air. He looks back at his time leading Ploughshares Fund and analyzes what lies ahead in a short interview with co-host Michelle Dover.
