Again, Hoplie poses as a great intellectual - by asking what appears to be a tough question. But all is simple: those in towns decided that all the land around an Islamoc state. What the heck islamic state is - visit USA-feed and backed Talibanese Afghan.
Come back (in one piece) and keep squeeking about Serbs who do not wish to live in islamic state.
Finally, they lost - and know what was done to them a bit later?
The Muslim residents of Bosnia's towns and cities that fell under the thrall of Radovan Karadzic were not as a group the fanatical adherents to Islam like they're made out to be - they did, however, own property and have valuables that could be extorted, stolen, or otherwise expropriated by Karadzic's followers.
Lastly, the US never supported the Taliban: Afghan history seems to be as mysterious to you as does that of Bosnia.
There's a price to be paid for being ignorant, and you'll continue to pay it until you address the deficiencies in your knowledge base.
