The muslims that he was at war with... albanian invaders... that is who did the beheadings... and Serbs are Christian.

Bosnian Serbs are Christians, and so were the Bosnian Croats they slaughtered. (Serbs are Orthodox, while Croats are Catholic.)
I know that they have been killing each other in the Balkans over religion for at least 800 years (since the Muslims invaded), but Bosnian Serbs did commit war crimes during the 1990s and should be held accountable.
