A strategic deterrent differs from tactical nuclear weapons that planners might expect to use in a limited way. A tactical strike offers no dependable route to de-escalation. Once nuclear weapons are used, the doctrines of other nuclear powers create a serious risk that many more weapons will follow. The value of a national arsenal therefore lies in deterring nuclear attack, not in presenting decision-makers with an apparently usable battlefield option.
