Didn't those in the grave live by the rule that the Serbs would either be dhimmi or die?
Here's a little 3 minute video made by a Bosnian Muslim. Most of the visuals are in English and the second half really tells the story to the 40+% of Bosnia's Christians and to Christian Serbia who is 80+% Christian. It basically tells Serbia that "you are next to be Islamicized!" http://www.youtube.com/watch?v=Zrcaed9nDmo
