Kaplan used systems analysis to differentiate among the various types of international state systems: the “balance of power” system, the loose bipolar system, the tight bipolar system, the universal international system, the hierarchical international system, and the Unit Veto International System. It was Charles Krauthammer who coined the term Unipolar System. Unipolarity in international politics is a distribution of power in which one state exercises most of the cultural, economic, and military influence.
