The end of the Cold War has terminated the bipolarity in the international system. However, International Relations Studies still pays less attention to the international power distribution after the bipolar system. Neorealists thought that the structural constraints of the international system would bring the world into a multipolar system. They insist that nowadays, the unipolar moment is just a transitional period toward a multipolar system. Some scholars believe that we are in a typical unipolar system in which the United States is the only hegemony.In an unipolar system, the hegemony will strive to maintain power supremacy relative to other actors, limiting policy choices to balancing and bandwagoning. The termination of the unipolarity could be either the rise of revisionist states or the decay of the hegemony. International Relations theories must to meet the challenges posed by the unipolarity system in order to improve their theoretic interpretations, explanations, and predictions. |
