In the vocabulary of International Relations (IR), States had traditionally been the centre of the discourse; such State-Centric elucidation concentrates on Westphalian model of Nation-State that laid down the foundation of contemporary state system and understanding of International Relations. Theoretically, the understanding of IR was dominated by Realist paradigm and field was often described as child of Morgenthau, Hobbesian, Machiavellian etc. revolved around the concept of Power. However, the end of Bipolarity witnessed a paradigm in two distinct ways. The first is in a geographical sense, with power moving from certain traditional strong states such as U.K, U.S to other states like China, Japan. Second is parallel where power is shifting from State to Non-State Actors (NSAs). Parallel Shift is more transformative and is substantially a different kind of shift. In such circumstances, new actors have increased its involvement in IR. Scholarly analysis in the discourse was built on State not NSAs. There is less comprehensive understanding on NSAs. If one agrees on parallel shift then such transformation needs further theoretical analysis. This book provides an analysis on parallel shift and uses ISIS to elucidate transformation that has been taking place in IR.
