The unintended consequences of deterring cyber attacks through nuclear weapons and international law
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.
