Perhaps they are supportive of the insurgency? You clearly haven't studied insurgencies at all. The water is at least nominally supportive of the fish. If it wasn't there wouldn't be any fish. I highly doubt you'll get that, but it is key as to understanding the role of civilians in insurgencies.What if the civilians realize that the reason they are dieing, is that the Tallies always start a fight amongst civilian areas? Are the Afghans too stupid to figure that out?
