In contemporary armed conflicts, youth are often on the frontlines of combat and, after peace accords are signed, they are both potential threats to peace and significant peace-building resources. Troublemakers or Peacemakers? breaks new ground by exploring youth actions, perceptions, and needs as central components of the challenge of post-war peace building. The contributors develop theory and policy recommendations based on field research in Sierra Leone, Rwanda, Guatemala, Colombia, Angola, Northern Ireland, Bosnia, and Israel-Palestine.
