From June 25 to 27, 2008, the Naval War College had the honor to convene an International Law Expert's Workshop, "The War in Afghanistan - A Legal Analysis." This volume captures the legal lessons of the war in Afghanistan as reported, studied and debated by a rare gathering of eminent scholars and practitioners of international law. The workshop's mission was to provide a comprehensive legal examination of the Afghan conflict-from the decision to use force, to the manner with which force was employed, to the legal construct for the evolution of military operations transitioning away from the use of force. Renowned international academics and legal advisers, both military and civilian, representing military, diplomatic, nongovernmental and academic institutions from throughout the world contributed to the workshop and this volume.
