2　本質的論争概念としての安全保障と批判的安全保障研究　乖離する「拡大」と「深化」

抄録

Discussions around the concept of the security guarantee have increased in recent years. One of the main points of these discussions concerns the issue of so-called “Redefining Security:” modern security is so complicated that it cannot be reduced to the traditional military-centric national security model. Areas outside of military affairs need to be examined as security challenges. The range of security activities and the rapid manifestation of new threats in recent decades need revising. In a multipolar world, the subject matter encompassed by the field of Security Studies is substantial.

As the “New Security Agenda” becomes more prevalent, the concept of national sovereignty, which is at the core of the security guarantee, and the limitations of military force now receive greater recognition. However, the military-centric conception of a national security policy remains deeply rooted. Particularly since 9/11, because of the muddled status of the ideas of “Old Wars” and “New Wars,” there is a need for a theoretical framework that captures the conceptual perspectives characterizing the relationship between military and non-military security policy.

This paper will reevaluate the theoretical debate, and the symbolic struggle for the political legitimacy surrounding the concept of the security guarantee, against the backdrop of the globalization of security policy. The majority of the discussions concerning the concept of the security guarantee since the end of the Cold War have tended to address the problems of the “Security Dilemma.” The divergence between the concept of security itself and national security policy is now treated as a genuine theoretical problem. Furthermore, this paper examines the theoretical significance of Critical Security Studies in recent years and the limitations of this field, while focusing on the impact of the historical structure and the discursive meta-structure surrounding the concept of security.
