-us Military Alliance After The Cold War "new Development" And East Asian Security

After the cold war, the Japan-U.S. Security Alliance did not withdraw from the international political arena, and instead it gained some new developments which showed the tendency of further strengthening and continual breakthroughs to the former frameworks for cooperation between the two sides.Although we could more or less get reasonable explanations to the specific international political phenomenon from the perspectives of Realism, Liberal Institutionalism and Constructivism and obtain the rationality and inevitability of the post-cold-war new developments of the alliance, we could not reject the judgment that the so-called new developments of the alliance are out of step with the times characterized by globalization.The security of East Asia has always been a sensitive issue full of variables. The new developments of the Japan-U.S. Security Alliance inevitably intensified the complexity of the security situations in East Asia. Comprehensive security issues including traditional security issues and non-traditional security issues have richer contents than either of the following two, and therefore they are attracting more and more attentions. The security mechanism for multilateral cooperation in East Asia guided by the Comprehensive Security Perspective is a better way than the security alliance to enhance security cooperation and maintain peace in East Asia.
