What Is the Relationship Between Alliance and Militarized Conflict? Analysis of Reciprocal Causation

초록

Despite the importance of alliances in international politics, little is known about how they theoretically and empirically affect militarized conflicts and vice versa. This study aims to examine the reciprocal relationship between alliances and militarized conflicts. The literature has focused only on the effects of alliances on militarized conflicts without paying much attention to the simultaneous causation between them. Thus, previous studies have not consistently revealed a relationship between alliances and conflict. Moreover, they are limited due to the use of dichotomous measures of shared alliance ties. Using a continuous measure of alliance ties, this study clearly demonstrates that shared alliance ties can be effective in reducing the likelihood of militarized conflicts. In addition, this study finds that there is a reciprocal relationship between shared alliances and militarized conflicts. It finds that militarized conflicts tend to decrease the level of shared alliance ties. Then, this study argues that alliance might be added to the next element behind the Kantian tripod as a salient factor that reduces militarized conflict. Finally, this study points to insights to be gained from the findings and suggests some policy implications.
