This document is based on a forthcoming book that unites two broad international themes: international criminal accountability and children’s rights. The book examines how a childrights approach has been gradually inserted into the practice of international tribunals. Child victims should be entitled to no less justice than adults. However, to testify on war crimes and be questioned in courtrooms may add to—not relieve—children’s trauma. Children can both suffer from and commit atrocity crimes. The book discusses the dilemma of child soldiers, who could be perpetrators of war crimes but are also victims of forceful recruitment, which is in itself a war crime. It demonstrates the growing child-protection culture at the UN and the cooperation among its agencies in combating the recruitment of child soldiers.
