Nuclear weapons are incompatible with elementary considerations of humanity.
Human security today is jeopardized not only by the prospect of states’ deliberate use of nuclear weapons, but also by the risks and harms arising from their production, storage, transport, and deployment. They include environmental degradation and damage to health; diversion of resources; risks of accidental or unauthorized detonation caused by the deployment of nuclear forces ready for quick launch and inadequate command/control and warning systems; and risks of acquisition and use by non-state actors caused by inadequate securing of fissile materials and warheads.
