which he did that and thats how the war in Bosnia started. 

The Bosnian war began because Yugoslavia (what was left of it) didn't recognise Bosnian's independence, and the president of SR Serbia (Milosevic) began arming Bosnian Serbs and encouraging separatism in Bosnia and Herzegovina. Or you could go earlier than that and blame it on a chain reaction caused by Slovenian declaration of independence.
