Listen: The world is heading toward a new nuclear arms race—one that’s more chaotic and dangerous than the last. The Cold War built rules of deterrence for a world of dueling superpowers and static arsenals. But in a fragmented, GZERO world of fast-moving technology and unpredictable leadership, the safeguards are fraying. On the GZERO World Podcast, Admiral James Stavridis, former Supreme Allied Commander of NATO, sits down with Ian Bremmer to discuss the growing nuclear threat and what we can do to stop it.
The indicators are alarming: China is stockpiling nuclear warheads at record speed. Russia continues to rattle its nuclear saber in Ukraine. Even US allies are privately and publicly questioning whether they need a deterrent of their own. So how serious is the nuclear risk? How do we guarantee security in a world where the weapons (and the rules) are changing? Are we ready for a future where not just missiles, but lines of code, could end civilization? Stavridis and Bremmer assess the current arms race and what it will take to lower the nuclear temperature.
“We're already involved in a proxy war with a nuclear power,” Stavridis warns, “We'd be smart to try and continue to have strong alliances to balance China and Russia drawing closer and closer together.”
