In this episode, Imogen Foulkes talks to Cordula Droege, Chief Legal Officer of the International Committee of the Red Cross, Beatrice Fihn of the International Campaign to Ban Nuclear Weapons, and Elaine Whyte Gomez, the ambassador from Costa Rica, who steered the treaty through the United Nations. Get in touch!
