States seek nuclear weapons not primarily in order to use them, but in order to take advantage of the security they offer. If states existed in a world post-disarmament, the incentives to develop nuclear weapons for reasons of security would not have disappeared, in fact they would have increased as no other state would be able to use their more powerful conventional forces against that state. As Paul Robinson notes, ‘conventional armaments…will remain the backbone of U.S. defence forces, but the inherent threat to escalate to nuclear use can help to prevent conflicts from starting, prevent their escalation, as well as bring (them) to a swift and certain end (Robinson, 2001)’. Such potential advantages will not be lost on states in a nuclear-free world.
