Since the end of cold war,the United States has made a series of adjustments to the missile defense policy.Missile defense has become a part of the extended deterrence and the core of the alliance strategy.This paper analyzes how missile defense become an important part of the US's Asia-Pacific alliance system,and summarizes the position or role of different allies,and the different modes of its participation in missile defense cooperation.The most important factors affecting the attitude of US's allies to missile defense are missile threat,specific implementation of the deterrence and defense functions of the US missile defense and the influence of the missile defense on the extended deterrence credibility.Missile defense deployment is a kind of coercive diplomacy to strengthen its alliance.With the aid of equipment deployment,the United States provides ally protection,the military exists can also used to control allies,contain its centrifugal tendency.Its functions in controlling allies are mainly embodied in two aspects.Firstly,The deployment will overflow the regional Security Dilemma and create new contradictions among the countries in the region,so as to provide new impetus for maintaining the alliance.Secondly,The continuous development of missile defense technology,as well as maintaining the group military advantage both in attack and defense will attract more regional countries to participate in the system.This article argues that the United States' Asia Pacific allies have different considerations in choosing whether to cooperate with the United States for missile defense and determine the degree of intervention,and form three different modes.Japan has the most serious sense of missile threat,transforming missile defense into the driving force of normalnationalization,which is embodied in the followed strategy.South Korea recognizes the high cost of participating in missile defense cooperation,but for security benefits and to ensure that the extended deterrence is credible,it accepts both the THAAD deployment and then it strengthen South Korea's offensive equipment,which is reflected as a hedge strategy.Australia,based on the threat of the North Korean intercontinental ballistic missile,strengthens the ability to monitor the South Pacific Air Defense and deal with the so-called Chinese threat,which is embodied in the speculative strategy.
