Power Cycle Theory, New Approach for Analysing Power Dynamic in International System

The issue of power transition in international system has been analyzed from different perspectives. Power cycle theory and role that have been suggested for the first time by Charles Doran, describes and explains the mechanisms, causes, and the quality of transition from one structure to new structure on the basis of neo-realism. This theory states that countries in process of moving on their power cycle, were fouled to critical statuses that confuse space for rational decision making in particular section of history. In this special section, distance between power and actor role suddenly was closed, and policy-makers noticed abruptly that tid of history has been reversed. This theory considers an equal importance for the role and power in statecraft, but with this difference that power is constrained unilateral and the role requires mutual acceptance. Accordingly, the mentioned theory along with the creating an adjustment in classical realism, accepts certain viewpoints in explaining the existing international order. Based on this, the power of each actor is considered relative, so that it can be assessed in comparison with other actors. Increasing the power of each actor, increases its role expectancy and this power challenges other superior power; therefore, the paramount power will be confronted with several options to contend with challenger power and for hegemony continuing. It is believed that this theory with objectivity and pragmatic approach and its principles, has remarkable ability to explain the relations between superior global powers. In this research has been attempted to analyse the theory of power cycle and role, and explain its strengths and weaknesses.
