Is the international community poised to outlaw the most destructive weapons ever created? In this episode, the International Campaign to Abolish Nuclear Weapons reports on the progress made at the May session of a special UN working group on nuclear disarmament in Geneva. There the vast majority of nations declared a readiness to start work on a treaty prohibiting nuclear weapons. 

Brazil, Mexico, Indonesia and the Philippines were among those proposing that the first negotiating conference be convened 2017. While few expect that the nine nuclear-armed nations will embrace this new law, proponents are convinced that it will be a powerful catalyst for change.
