When I first visited the Democratic Republic of the Congo in 2007 as a public health researcher, I was trying to understand the complex issue of how young men get recruited into rebel groups in war-torn regions of central Africa. What I learned was both surprising and heartbreaking: a person who experienced war violence as a child could be more likely to engage in conflict as a young adult. Young men who had experienced extreme war violence in their past would often state this as a reason to take up arms. Even more tragically, these same young men would often struggle to reintegrate peacefully into their communities when hostilities ended. The violence they had experienced their whole lives through war persisted within their homes and communities even when formal peace was declared.
