Potentials of IR Theories for more Convergence and Interactions with IL

Although the discipline of IL is hundreds of years old , the academic field of IR is of much more recent vintage .After The first world war , the disciplines of IR and IL overlapped substantially . But with the occurrence of the World War II the era of disciplinary convergence ended .Many realists believed in an anarchical world, international agreements could not meaningfully constrain state actions. These tendencies were reinforced by a structural realist literature that viewed international outcomes as a product of the distribution of capabilities and power across states. By the early 1980’s liberalism had emerged as a coherent theory of IR. Liberalism claims that the configuration of independent state determines state behavior. Since the end of the cold war, constructivism has emerged as a significant approach to bridging two fields. However its sophisticated understanding of norms makes possible a sociologically rich and historically grounded understanding of international law. The focus of this article is on the analysis potentiality of IR theories, i.e., English school, Realism, Liberalism and Constructivism for more interactions and convergence of IR and IL .Our study demonstrates the degree of convergence is greater between IL and IR than other areas.
