Fifty countries recently signed and ratified the UN Treaty on the Prohibition of Nuclear Weapons, which will take effect in January 2021. This marks a major milestone in international efforts to ban nuclear weapons, but notably, the United States, its allies, and all other nuclear-armed states refused to take part.  

So what effect, if any, will the treaty have on international security and nuclear disarmament efforts? And how will treaty promoters attract additional states to sign and ratify it? Join Beatrice Fihn, Togzhan Kassenova, Zia Mian, and George Perkovich for a conversation on the future of the nuclear ban.
