“The Sweet Voice of Reason”
The Szilard Advisory Board (SAB) is composed of a select group of experts at the intersection of policy and politics dedicated to reducing the threats posed by weapons of mass destruction (WMD).
A project of the Center for Arms Control and Non-Proliferation, the SAB will add clear analysis, expert opinion, and insights based on experience to the public discourse on international security.
The Board is named after Leo Szilard, the founder of Council for a Livable World, the Center’s affiliated organization. His work to bring the “the sweet voice of reason” to the nuclear policy conversation is more important than ever today. In honoring his memory, the SAB will continue to push for new and better ways to advance arms control and nonproliferation goals.
