A study of deterrence, amongst the trends of international strategic and security studies in the early 1950s, became a notable one for its irresistible attractiveness. Because of its value in studying interstate conflict, the study of deterrence has become the key concept for the understanding of “war” and “peace,” which has long been regarded as major themes for international relations theory. From the perspective of deterrence theory, structural deterrence and decision-making deterrence offer both an empirical and logical explanation of the workings of bilateral conflict. Structural deterrence theory, taking a broad perpective, stats mainly from the understanding of functions and values of the international system. The decision-making deterrence theory, on the contrary, studies actor behavior and policy maker strategic choices. Fundamentally, both structural deterrence theory and decision-making deterrence theory base their goals on maintaining status quo.
