Let us assume, for a moment, that you are a Westerner and/or that you care for the US. In that case I can tell you that you can back up Serbs or Muslim. What happens when West arms, equip and train Muslim forces we saw in Afghanistan – sooner or later they will turn on you. If that is OK with you so be it. You do your work - as for Serbs “Patience - Rescue".
Who started war in Bosnia:
1991 --- VOX magazine cover from October 1991 showing Bosnian Muslim soldier in Nazi SS Division Handzar stepping on decapitated heads of Serbian leaders. Caption reads: "Spremna Handzar Divizija" (The Handzar Division is ready).

The Bosnian Muslims were very secular before the war and still are today. The Afghan mujaheden, by comparison, were completely insane from day one and Reagan knew it. They were simply a force the US backed as a way of giving the Soviets their Vietnam. The legacy of that decision is positive in some ways (no more USSR) and horrible in others (more Islamic fundamentalism).
Funny that you mention a Bosnian magazine from October 1991.
At about the same time....
"You want to take Bosnia-Herzegovina down the same highway of hell and suffering that Slovenia and Croatia are travelling. Do not think that you will not lead Bosnia-Herzegovina into hell, and do not think that you will not perhaps make the Muslim people disappear, because the Muslims cannot defend themselves if there is war-How will you prevent everyone from being killed in Bosnia-Herzegovina?"
- Radovan Karadzic, October 14, 1991 (said to the Muslims at the Bosnian parliament).
So what do you think had more to do with war starting, a magazine story or an open threat of genocide?
