In July 1995, in the United Nations mandated "safe area' of Srebrenica, Serbian forces summarily executed some 8,000 Bosnian men. The forces of the Army of Republika Srpska, led by General Ratko Mladic (still at large in Bosnia for war crimes), "stripped all the male Muslim prisoners, military and civilian, elderly and young, of their personal belongings and identification, and deliberately and methodically killed them solely on the basis of their identity.", according to a press release by the President of the International Criminal Tribunal for the Former Yugoslavia (ICTY), Judge Theodor Meron.
Following a NATO led mission to intervene in the conflict, former Yugoslavian President, Slobodan Milosevic, was indicted by the ICTY in May 1999 for war crimes in Bosnia and Croatia, and for genocide, also in Bosnia. Milosevic was the first acting head of state to be indicted for war crimes, however, his death prior to conclusion of his trial at The Haque has left a longing for justice in the region. Nonetheless, his trial implicated his direct contribution to the Serbs during the Bosnian conflict.
The indictment of Serbia, in addition to those against individuals such as Milosevic, raises interesting questions regarding international law. The ICJ has in the past conducted legal proceedings on state-centric grounds. For example, Yugoslavia filed suit against the United States for its use of force in the Bosnian campaign, and not, for example, against President Clinton or General Wesley Clark. War crimes allegations, however, have typically been focused on the behavior of individuals, and not the collective actions of the state. Considering other cases involving the Sudanese backed Janjaweed, the indictment of Serbia may be signal a paradigm shift in international law.
