A coming Age of Micro Game of Power
The traditional theory of international relations, whether it is realism, liberalism, constructivism, or scientific behaviorism, define sovereign states as a unified body in international arena. It has consistent interests, and naturally also has consistent foreign policy goals and means. In the 20th century, and especially during the two World Wars and the Cold War, this conceptual abstraction was very accurate. But after the end of the Cold War, especially in the 21st century, this concept gradually went against the reality of international relations. On the one hand, the comprehensive strength of a country cannot directly transform competitive advantages in specific areas; on the other hand, the main resistance of many countries, including superpowers, may not be another power, but different domestic interest groups as well as international non state actors. This has caused traditional international relations theories, from hypotheses to conceptual and inferential levels, to be unable to explain the world today.
