The security policy community and the consensus on the US–Japan alliance: the role of think tanks, experts and the alliance managers

Abstract

The article addresses the issue of continuity of the consensus on the US–Japan alliance in the post-Cold War era, by employing the concepts of a security policy community (SPC) that comprises both government office-holders and non-governmental actors focused on the foreign and security policy. The main argument is three-fold; firstly, one of the major forces behind the continuity and enhancement of the security consensus on the US–Japan alliance has been the formation of the transnational SPC that includes members from the US and Japan; secondly, since the end of the Cold War, the SPC has developed a dense network of members, institutions, and practices that supports the advocacy of alliance enhancement as well as community cohesion and nurturing of new members; and thirdly, the think tank- and university-based experts play an increasingly vital role in the formation and dissemination of the security consensus. The article suggests that such arrangements can have both positive and negative consequences and that a proper balance between openness and exclusiveness, expertise and novelty, and continuity and innovation is required in order to maintain a vibrant marketplace of ideas for security policy. The article also indicates that with the transformation of the Indo-Pacific security architecture from the hub and spoke to the networked system, SPC might serve as a model in other US alignments.
