How acceptable is the international society as an approach in International relations?

International relations is the harmony and diverse co operation of diverse nature among the nations of the world that constitutes the international society.The international society has emerged in the changing historical and political environment with modification of power,state system,technological changes but the international relations has changed little in the pattern of relationship between states after WW I-WW II with power politics as the main element.The post cold war too has resulted in an era of despair in the environmental issues,terrorism and confrontation with the hegemony of the unipolar nation.The international society lacks the political and social homogeneity with mutal interest to be acceptable as an approach to international relations.
