Containing the Risk: Biological and Nuclear Threats in a Divided World
Sergey Radchenko, Deborah Rosenblum, and Ariane Tabatabai explore how the world can manage biological and nuclear risks amid deepening geopolitical divisions.
The threat posed by the world’s most dangerous weapons has long demanded cooperation, even among adversaries. Today, the safeguards built to manage those threats are under growing strain. Advances in biotechnology are creating new risks, questions around laboratory safety and biological weapons are taking on new urgency, and decades of progress on nuclear arms control are eroding. How prepared is the world to prevent an accident from becoming a global catastrophe? Are existing safeguards equipped to manage today’s biological and nuclear threats? And can countries cooperate to contain these risks amid growing geopolitical competition? Join Sergey Radchenko, Deborah Rosenblum, and Ariane Tabatabai for a conversation on managing biological and nuclear threats in an increasingly divided world.
