The CTBT “20 Years 20 Voices” video series presents diverse perspectives on the topic of abolishing nuclear testing and the importance of the Comprehensive Nuclear-Test-Ban Treaty. Now in its 20th year, the Treaty is at a crossroad. Where to go from here, and how? Hear from a Hiroshima school girl, to a former head of a nuclear weapons lab; from world renowned scientists, to former Secretaries of State, to a survivor of nuclear testing. The anniversary series examines why a legally-binding global ban on nuclear testing matters today, more than ever.
