Don't forget the brave Dutch battalion that protected the civilians of Srebrenica in the secure UN enclave, oh wait, they didn't, they handed them off to Serb forces to be executed.
It was a badly thought out mission that was handed to the wrong unit and didn't receive any of the support it needed. There's no way a light infantry battalion could have defended Srebrenica from Mladic's army. It was theatre based on the hope that Mladic wouldn't attack.
While it was a particularly poor showing for a UN mission, and badly handled at every possible level, I don't think it's comparable raping children. It wasn't the UN soldiers who murdered the civilians, they were just completely unable to prevent it, and provided only an illusion of defense.
The pattern of civilized diplomats and governments being incapable to handle or even imagine the dog-dominates-dog perspectives of aggressors, even chastising parties acting appropriate, while being placated by other diplomats- who try to gamble for time, to create facts on the ground.
If anything, the doves are way to often the pets of the butcher.
