I spent some time in Sreb and can assure you that the small Dutch contingent had no chance of protecting this 'safe' haven. The UN's generally limp wristed policies with regard to their involvement (or not!) in the course and conduct of the war essentially cleared the way for the Serbs unfortunately.
Hindsight's a great thing but I suspect if someone had made a robust (and possibly suicidal) stand against the Serbs once their intentions were clear then we might have saved a few thousand lives...........
