That genocide that happened in the Yugoslavia wars of the 1990s ....well according to the UN ,it really didn't happen.
U.N. court: Serbs' actions in Croatia not considered genocide - CNN.com
You see ,ethnic cleansing isn't really genocide. Tell that to the 100,000 victims of the ethnic cleasning . Tell that to Bosnian Serb leader Radovan Karadzic ,who in 2001 was convicted of genocide and sentenced to 46 years in prison.Slobodan Milosevic would've been sentenced too if he didn't have to courtesy of being found dead during his trial.
I'm sure the Islamic State is comforted over this decision.
