A new report published from the European Leadership Network’s New European Voices on Existential Risk (NEVER) project calls for a systemic international approach to be taken to address man-made existential risk. The risks from nuclear weapons, climate change, biological threats, and AI are interconnected and cross-cutting lessons should be drawn.
Using nuclear deterrence to prevent cyber attacks presents not only ethical and strategic challenges but also significant legal concerns. International law imposes strict limits on the use of force, making a nuclear response to cyber attacks highly questionable. Attribution remains difficult, escalation risks are high, and proportionality concerns persist. YGLN member Verena Jackson writes that a more effective approach would focus on strengthening international norms, improving attribution mechanisms, and—above all—prioritising cyber resilience over expanding nuclear deterrence.
Scientific advances have renewed a discussion around the possibility of potentially devastating biological attacks. Eva Siegmann writes that nuclear deterrence is inadequate to deter biological threats. Instead, the threat of biological weapons should be addressed via international efforts rooted in transparency and cooperation. Leveraging the mechanisms of the Biological Weapons Convention and implementing deterrence-by-denial strategies can effectively mitigate risks.
The threats the UK faces today are more nuanced and diverse than in the Cold War era, ranging from state-sponsored cyber-attacks to sophisticated disinformation campaigns. ELN Policy Fellow Nikita Gryazin argues that these challenges require a shift in focus from traditional nuclear deterrence to modern defensive and offensive cyber capabilities.
Listen to the final episode of the NEVER podcast – Ok, Doomer! This episode takes a step back to assess what we’ve learned about existential and global catastrophic risks in previous episodes, and what comes next. Featuring a discussion of how ordinary people can get involved in existential risk mitigation, what ongoing efforts will prove most successful in creating a framework to deal on these topics, and how the example of the Nuclear Non-Proliferation Treaty demonstrates that global cooperation to deal with the biggest threats we all face is possible, even in a tense geopolitical climate.
The United Kingdom’s latest nuclear doctrine suggests that severe cyber-attacks on their national or critical infrastructure could provoke a nuclear response. Despite this, cyber-attacks against the UK have surged over the past decade. Eva-Nour Repussard, YGLN member and Policy Fellow at BASIC, writes that instead of deterrence by punishment, the UK should seek to increase its resilience to cyber-attacks and focus on a strategy of deterrence by denial regarding cyber threats.
