The book is organized in three sections. The first section outlines the contemporary dynamics of the arms race in the Middle East by focusing on its most recent dynamics and their implications for regional and international security. The second section conducts systematic analysis of case studies of country-specific drivers of the armsrace. The third and final section examines the role of external actors in the arms race, evaluating both the responses of regional actors to external interventions as well as the implications of the arms race for extra-regional countries.
