Linking Trauma to the Prevalence of Civil War

: This article argues the more trauma endured by a population, the more civil war the country will experience in the future. Drawing on mental health, trauma, and neurobiological research, it builds a new theory of civil war that fills existing gaps in current civil-war literature, and then tests the theory via statistical analysis of a large sample size (large-n statistical analysis). The conclusions will help policymakers and US military leadership better understand civil wars and the limits of American power to end them.
