The United States and the International System: From a Unipolar Order to a Nonpolar Order
New developments in the arena of international relations require us to distance from a traditional understanding of these relations in order to recognize new forces that affect their dynamisms, new trends and results, as well as the procession of new concepts in this arena. This research will at first review developments in the United States’ foreign policy during the past two decade and discuss major theories related to the distribution of capabilities and configuration of the international system. Then it argues that in the existing international system, like the previous one, good understanding of the polarity will help better understanding of developments in international relations. However, stopping at this point and failing to recognize new forces, which have undeniable effects on international dynamisms, trends and results, will lead to an incomplete understanding of phenomena in this arena. In this research, the concept of nonpolar order is proposed; a world order in which power is no more intergovernmental, limited and inflexible, as it was in the past, and has assumed new dimensions.
