In July 1985, French intelligence operatives planted explosives aboard Greenpeace’s Rainbow Warrior while it was docked in Auckland, New Zealand, killing photographer Fernando Pereira. The attack was intended to disrupt protests against French nuclear testing in the Pacific, but it triggered an international scandal when investigators traced the operation to France’s intelligence service. This episode examines how a government conducted a lethal clandestine operation inside the territory of a friendly nation. It explores state responsibility, sovereignty, international arbitration, and the limits of intelligence operations conducted in the name of national security.
