The Establishment of the "Alliance": U.S.-Japan Security Relations in the 1950s

本研究以美日两国关于使用驻日军事基地的协议为中心，探讨美日两国在1951年安保条约的基础上如何建立安全保障关系。这种关系的核心是美军使用日本的基地和设施，而不是整个20世纪50年代的集体防御，部分原因是日本的自卫意愿和能力相对较差。本研究认为，美日两国政府在军事基地利用问题上建立了习惯、制度或体系，如20世纪50年代的事先磋商制度，从而强化了两国的安全关系--同盟关系。

This study tries to show in what way the United States and Japan built the security relationships based on the 1951 Security Treaty, mainly focusing on the formation of agreements between two countries with regard to the utilization of military bases in Japan. The core of this relationship had been U.S. forces' use of bases and facilities in Japan, rather than collective defense throughout the 1950s, partly because Japan's will as well as capability of self defense was relatively poor. This study argues that the U.S. and Japanese governments had established custom, institution, or system on the utilization of military bases, such as prior consultation system in the 1950s, which resulted in strengthening the bilateral security relationships--the alliance.
