New Article on Deterring Wartime Atrocities

Civilians typically bear the brunt of suffering in contemporary conflicts.  Long after liberated Nazi concentration camp survivors held up the first sign declaring, ‘Never Again!’ civilians have faced genocide in Bangladesh, Burundi, Guatemala, Cambodia, the former Yugoslavia, Rwanda, and Darfur.  Sexual violence, torture, and forced disappearances also count among the innumerable horrors that civilians continue to endure.

In the 1990s, international officials sought to respond to such suffering by establishing a new generation of wartime international criminal tribunals (ICTs or war crimes tribunals).  In particular, in 1993 the United Nations Security Council created the International Criminal Tribunal for the former Yugoslavia (ICTY, or Yugoslav Tribunal).  The ICTY paved the way for the establishment of the permanent International Criminal Court (ICC) five years later.  Unlike earlier ICTs in Nuremberg and Tokyo—as well as recent war crimes tribunals in Rwanda, Sierra Leone, Cambodia, East Timor, Lebanon, Bosnia, and Kosovo—both the ICTY and ICC are mandated to prosecute international criminal law (ICL) violations committed in the context of active armed conflicts.  In so doing, the ICTY’s and ICC’s founders hoped that they might, among other things, deter combatants in those conflicts from perpetrating violence against civilians.

Over 25 years after the establishment of the first wartime ICT, there are still more questions than answers regarding these institutions’ role in deterring atrocities.  Skeptics contend that, in the heat of battle, combatants are unlikely to perceive a substantial risk of international legal punishment.[i]  Moreover, ICTs face formidable political obstacles that impair their ability to secure arrests and convictions, and thereby enforce the law.  Pessimists argue that if an ICT were in a position to arrest weak combatants (including rebels), doing so might motivate encourage them to escalate attacks on civilians to gain leverage that would help them to evade international criminal prosecution.[ii]  In contrast, optimists argue that ICTs can deter violence against civilians so long as their officials secure the prosecutorial support necessary to punish war criminals.[iii]

In a new article—”Deterring Wartime Atrocities: Hard Lessons from the Yugoslav Tribunal” appearing in International Security (edited at Harvard University’s Belfer Center for Science and International Affairs)—Dr. Jacqueline R. McAllister argues that none of the aforementioned views fully captures how and when wartime ICTs might deter atrocities against civilians.  Insights from criminology, as well as research on civil conflicts and international legal compliance, suggest that ICTs are most likely to deter government and rebel forces from committing atrocities against civilians when all three of the following conditions are present: (1) ICT officials have secured sufficient  prosecutorial support, (2) combatant groups rely on support from liberal constituencies, and (3) combatant groups have  centralized structures. Case studies of the ICTY’s impact on fourteen combatant groups from the Yugoslav conflicts—combined with hundreds of field interviews with war veterans and others involved in hostilities (whose perspectives have been missing in existing studies on international criminal deterrence)—confirm these predictions.  The ICTY’s record thus sheds important sight into how and when contemporary wartime ICTs—including the International Criminal Court—might succeed in deterring combatant atrocities against civilians.
