postmodernity and investigating the sovereign national state in the theories of international relations

the international relations course was basically under the dominion of positivistic realistic (and in its newest form, the neorealistic) tendencies, and accordingly provided some concepts as a basis for analyzing the international relation and global policies. but since 1980s and under the influence of the changes caused by the emerge of post structuralist and post modernist approaches in the area of social sciences, the science of international relations, too, experienced some theoretical changes. intellectuals who used post modernist approach in the area of international relations, emphasized that the basic concepts and the foundations of analyzing the international relations theories are basically some theoretical constructs which the traditional realistic approach has imposed as reality on the area of analyzing the international relations.
