This is one of the sources of the appeal of Balkans for "foreigners" and one of the sources of frustration and despair for the Balkan people themselves.

We never dealt with these issues in any way whatsoever. As is the cultural norm of all of the Balkan people, shit that we don't want to deal with is pushed away, compartmentalized and annotated (for future ammunition against those who have caused the atrocities). This left the entire region susceptible to manipulation by those who wished to tear the region apart. A lot of anger has built up during the 50 years between Jasenovac and the wars of the 90s.

(Full disclosure, I'm a Bosnian Serb, as well)
