3. In the Name of Peace

This final episode addresses the legacy of the Red Bomb, and the steady stream of scientists who became disenchanted with the project after seeing the potential devastation it could cause. By the time the Stalinist regime gives way to the era of Khrushchev, Russia and its rival are almost neck and neck. One war may be over, but another is just beginning. As rivalry deepens into outright hostility, can the quest to produce the ultimate atom bomb really be explained "in the name of peace"? As the race accelerates, simple bomb tests are replaced by full-scale battle exercises and the spectre of nuclear war looms ever closer.
