An arms-control advocate accepts an invitation to the dacha of a hard-partying North Korean power broker. There, through a haze of smoke and propaganda, they identify some common ground and set out to test a hypothesis: That it’s possible for Americans and North Koreans to work together toward peace. The result is a tense but extraordinary moment in the relationship between North Korea and the West, a rare example of collaboration that has been almost entirely lost to history.

This episode features Peter Hayes and Lyuba Zarsky, co-founders of the Nautilus Institute for Security and Sustainability, and David von Hippel, an energy expert who worked with Peter in North Korea.
