On 27 April 2016, United Nations Secretary-General Ban Ki-moon addressed an audience, ranging from veteran officials to young leaders, on the need for the entry into force of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The event was held in Vienna, Austria, but was followed across the world via media coverage, livestream, and social media.
"I find hope in the work of long-established groups such as the Arms Control Association...[and] I find hope in younger anti-nuclear activists and the movement around the world to formally ban the bomb."
