The aim of this thesis is to analyze the framework of deterrence theory whether it may be suited to the Nuclear, Biological and Chemical (NBC) terrorism as an asymmetrical threat. As a methodology, mainly qualitative means were applied. This thesis will argue that though the classical deterrence theory was primarily created for inter-state relations, its main premises and newly transformed features –due to the post-cold war era- can be applied on the asymmetrical relations between states and terrorist organizations which would initiate to use NBC material in particular. In the analysis of the problem of managing asymmetrical deterrence through revisiting orthodox ground of deterrence; the nature of the new threat and critics of classical theory of deterrence were discussed together to shape a unique asymmetrical deterrence. In conclusion, this thesis was finalized with the argument that to overcome the deficiencies of prevention models against asymmetrical threats as well as to remove obstacles for conducting a feasible deterrence theory against asymmetrical threats; benefiting from the deconstruction of classical deterrence theory is necessary in terms of recalling the concepts of rationality, capability and credibility.
