Also, do you know anything about the Muslim Green Berets, or did they only fight Serbs?
What are your estimates for how many foreign Muslims were there at some point during the war?
They could have curtailed them, but that would have stalled the flow of money from the Islamic world. The Green Berets were mostly fighting the Serbs in the Sarajevo-Tuzla corridor. There were probably around 1,500 Mujahideen in my very conservative estimation.
