Book excerpt: Mass Atrocities, Risk and Resilience examines the relationship between risk and resilience in the prevention of genocide and other mass atrocities and explores two broad areas of neglect. In terms of prevention, there is very little research that analyzes how local and national actors manage the risk associated with mass atrocities. In the field of comparative genocide studies, to date there has been very little interest in examining negative cases. Although much is known about why mass atrocities occur, much less is established about why they do not occur. The contributions in this book address this neglect in two important ways. First, they challenge commonly-accepted approaches to prevention. Second, they explore negative cases in order to better understand how local and national actors have mitigated risk over time.
