Report No.204: The Potentially Revolutionary Impact of Emerging and Disruptive Technologies and Strategic Conventional Weapons on Nuclear Deterrence

This report posits that the combination of emerging and disruptive technologies and strategic conventional weapons may have a revolutionary impact on the future of nuclear weapons. While emerging and disruptive technologies may yield additional arguments to keep relying on nuclear weapons to defend against them, they are often regarded as destabilizing for the global nuclear order, which makes it more likely that nuclear deterrence will fail and nuclear weapons will be used. At the same time, strategic conventional weapon systems (including hypersonic missiles) have deterrence characteristics comparable to nuclear weapons.  Because they could be used in a way that at least seeks to comply with jus in bello principles, by minimizing civilian harm (in comparison with nuclear weapons), they are also more credible as a deterrent. This may in turn increase political willingness to seriously consider fully delegitimizing nuclear weapons, and eventually replacing them with the default option: modern conventional weapons.
