Nation such as Bosnian doesn't exist. They are all Serbs but during a rough periods in history some of them changed the fate in order to stay alive. Kusturica is Serbian if I'm not mistaken. He wouldn't be crazy enough to participate a Serbian rally and speak against USA government otherwise, at least not in front of 200k people (Serbian people). I'm looking forward to watch his new documentary movie about Maradona, a famous Argentinian football player. Maradona himself said that this movie is the best ever made about him and that it is the real truth about him.
