This book tells the compelling story of how the UN International Criminal Tribunals for the former Yugoslavia and Rwanda prod states implicated in atrocities to hand over their own leaders for trial. Without state cooperation, the United Nations would fail in its mission to help bring perpetrators of war crimes to justice and to rebuild and reconcile war-torn societies. The tribunals' relative success in overcoming state resistance to international trials is the outcome of a political process that Victor Peskin uncovers and explains. This is the first in-depth, comparative study of state cooperation in the tribunals.
