The realistic discourse based on "State" which assumes State as the only interactor in the field of politics and international relations, has been changed and redefined due to the following factors: new developments of the post Cold War era, globalization, interdependency, spreading role of transnational social movements, global civil society, national and international NGOs and growing terrorist groups. The present study while using James Rosenoua's triple approaches on International Relations, intends to illustrate the transition from an interactor attitude of State in Realism, and also to survey its conceptual developments in an age when Pluralism is its prominent aspect. Finally the author concludes with evaluation and criticism of the current views on State.
