The efforts to explain the Srebrenica massacre as motivated by revenge have been dismissed as bad faith attempts to justify the genocide. The ICTY Outreach Programme notes that the claim that Bosnian Serb forces killed the prisoners from Srebrenica in revenge for crimes committed by Bosnian Muslim forces against Serbs in the villages around Srebrenica provides no defence under international law and soldiers, certainly experienced officers, would be aware of the fact. To offer revenge as a justification for crimes is to attack the rule of law, and civilization itself, and nor does revenge provide moral justification for killing people simply because they share the same ethnicity as others who perpetrated crimes. The methodical planning and mobilization of the substantial resources involved required orders to be given at a high command level. The VRS had a plan to kill the Bosnian Muslim prisoners, as Bosnian Serb war criminal Dragan Obrenović confirmed.
