Honestly, I don't know what to believe about this region.
Believe a couple of things:
1) A friend with experience in the region was once chastised for being too correct when he described the atmosphere as "hate you can taste."
2) Don't know about Bosnia, but Kosovo is headed for another blow-up within a year because the UN is setting them up with false expectations that they'll receive independence very soon. When reality hits home, they'll be at each others' throats again.
