||Since the end of the Cold War, the proliferation of intra-state conflicts has challenged policy-makers and international organizations to devise new and more effective mechanisms of crisis response. This study explores interventionary behavior of alliances in local conflicts in the context of conflict management. The main objective is to account for the discrepant interventionary behavior of NATO allies in Bosnia and Kosovo in the 1990s. The author develops several game theoretic models and then applies them to the two case studies. Finally, a controlled comparison is performed in an effort to extrapolate and generalize about the most crucial variables that influence the effectiveness of joint interventions.
