The Rest Is PoliticsWhy Nuclear War Is More Likely Than You Think (with Carlo Rovelli)
24 Sept 2026 · 18 minHumanity's current disengagement from the reality of nuclear risk, coupled with geopolitical shifts and the integration of AI, makes nuclear war significantly more probable today than during the Cold War.
Summary
This conversation challenges the common perception that nuclear war is an outdated concern. Carlo Rovelli argues that several converging factors, including geopolitical multipolarity, the advent of AI in military decision-making, and public complacency, have elevated the risk beyond Cold War levels. The core warning is that a disaster may be imminent precisely because people believe they are avoiding it through current rearmament strategies and a lack of public discourse.
Interesting ideas
Four Drivers of Increased Nuclear Risk. Rovelli identifies four key reasons the risk of nuclear war is higher today: public disengagement, the shift from a two-superpower to a three-superpower world (US, Russia, China), the integration of unreliable AI into rapid decision-making processes, and the resulting geopolitical instability. This challenges the assumption that the end of the Cold War made nuclear threats diminish, suggesting the current landscape introduces new, complex pathways to conflict.
Small Powers vs. Great Powers in Nuclear Escalation. The guest argues that while small nuclear powers (like North Korea or Israel) are often cited as a risk, the true existential danger comes from large nuclear powers. Small states are more deterred by the certainty of their own destruction, whereas a large power with a perceived technological advantage might be tempted to launch a first strike to achieve global nuclear dominance, radically altering the strategic stability established during the Cold War.
European Rearmament as a Pathway to Catastrophe. Rovelli criticizes current European rearmament efforts, particularly in Britain and Germany, as dangerously short-sighted. He argues that this increased military spending, often justified as a deterrent against Russia, actually increases the likelihood of catastrophic war by prompting Russia to escalate its own nuclear capabilities, drawing Europe into a dangerous and potentially suicidal arms race rather than fostering long-term stability.
Questions worth thinking about
If the 'game of three' nuclear powers is inherently more unstable, what specific mechanisms could be developed to restore a sense of mutual deterrence or de-escalation?
Given the perceived unreliability of AI, how can militaries balance the desire for speed in decision-making with the need for human oversight to prevent catastrophic errors in nuclear command and control?
