Explaining wars of choice: An integrated decision model of NATO policy in Kosovo

This study explains the behavior of democratic states during wars of choice using an integrated decision model. Integrated models are an attractive choice for explaining multifaceted decisions, particularly when simpler, existing theories have an uneven or only partial ability to explain conflict behavior. To illustrate these points, this study assesses the behavior of key NATO members during the 1999 intervention in Kosovo. I compare the behavior of France, Germany, Italy, the U.K., and the U.S. with the expectations of theories of collective action, balance of threat neorealism, public opinion, and government institutional structures. As an alternative, I introduce a simple, integrated, decision-making model that incorporates the core concepts from the other explanations in a staged, conditional manner. The integrated model does a better job of explaining state behavior in Kosovo than do existing theories. The integrated model also is applicable to other conflicts. The results of this study, and the potential of integrated models, have implications for our thinking about foreign policy analysis, for behavior during military interventions and the fight against terrorism, and for future U.S. leadership of alliance and coalition war efforts.
