| Outline of Final Research Achievements |
This project assessed the impact of Japan's changing defense policy on its security environment. Specifically, I combined theoretical and empirical approaches to investigate the role played by the right of collective self-defense (CSD). Theoretically, several game-theoretic models are developed and analyzed to explore ramifications of this policy change. The equilibrium analysis shows that allowing for the CSD alone does not improve the reliability of alliance commitment or enhance the effectiveness of extended deterrence; but it ameliorates the security dilemma as long as Japan commits to a hardliner bargaining position. Empirically, I assessed the relative impact of the defense obligations in alliance (and the lack thereof). The analysis of the past 2 centuries shows that symmetric defense obligation restrains an alliance partner from initiating a militarized dispute and enhances general deterrence, but it does not affect the risk of entrapment or being targeted in a dispute.
