Since the military costs for each state to give up a particular weapon are highly technical information that only the military actor (MA) can accurately measure, CL utilizes the advisory function of MA. However, parochial interests of MA create incentives to resist disarmament whether the target weapon is truly indispensable or not. Hence, MA fails to send a credible signal regarding the necessity of the weapon, leading to CL's irrational acceptance of the humanitarian disarmament treaty. This implies a paradoxical situation: even though the military dominates information, it cannot effectively influence policy outcomes. I test this logic by examining Japan's response to the 2008 Convention on Cluster Munitions. キーワード:軍縮、軍備管理、政軍関係、情報の非対称性、国際関係理論
