In the instances of small-scale crime we accept that if a community condemns a person’s action, our sense of justice demands that they be punished. However, it is often the case that those who commit the most heinous crimes at the highest levels of responsibility are not prosecuted because of the complexities of the process. For example Slobodan Milošević the former leader of Serbia’s trial took four years and he died before the verdict was given. According to ICTY Chief Prosecutor Carla Del Ponte “The death of Slobodan Milosevic deprived victims of justice”.[i] As an international community we have repeatedly pledged to prevent war crimes, in recognition of the fact that they are beyond the scope of local courts. When they occur it is a collective failure to protect, so the responsibility to prosecute and make amends falls with the international community. An admission of our inability to prosecute war crime undermines the decades of work we have done to prevent them.

An accepted tenet of most justice systems is the achievement of deterrence. Without the prosecution of war crime, its perpetrators have to consider no tangible cost to their actions. This applies to those who claim to have “just followed orders,” who now face a counter-motivation to refuse or defect.  In the case of high-level war criminals it becomes effective when they realise they are losing a conflict. If they fear prosecution they are more likely to seek to negotiate rather than going on a final destruction spree. In the final days of the Nazi regime, Himmler stopped committing atrocities and attempted to negotiate peace because he realised his own vulnerability to prosecution.[i]

The intention of many crimes of war is to destroy and demoralise individuals and communities. As a result, they often cause on-going harm to victims who cannot feel safe in their communities even after the conflict has ended. For victims, prosecuting war criminals has a vital cathartic function in helping them, to some extent, to come to terms with the crimes committed against them and their families. While full compensation is impossible, both the symbolic realisation of justice and the illustration of real commitment to prevention allows people to rebuild their lives to some extent. Failure to prosecute sends victims a message that the attacks on their freedoms were somehow acceptable.

For post-conflict societies to function, the tensions and divisions of the conflict must be brought out into the open and dealt with in order to be fully put to rest. Those most responsible for war crimes must be brought to justice, those involved in the regime but less culpable must have opportunity to make amends and victims must feel that they have been compensated. This allows compromise and the potential for effective governance. The alternative is to allow undiscussed, simmering hatreds and resentments to persist, which undermine growth and create a risk of further conflict.
