Great powers have frequently become embroiled in costly wars in peripheral regions that pose no direct threat.... In this historically rich and theoretically elegant study, Taliaferro tackles the question of why states persist in such counterproductive interventions.... It provides a useful cautionary message as the United States embarks on far-flung counterterrorism operations in the periphery.(Foreign Affairs) Taliaferro skillfully blends two lines of theorizing defensive realism and prospect theory, to explain the conditions under which leaders of great powers are more or less likely to adopt risky foreign military policies.... Balancing Risks is a thoroughly researched and well written addition to the literature.(Virginia Quarterly Review)
