Justice is only done when both parties in a conflict have been trialed for their crimes.
In Yugoslavia, this was not at all the case.
There is no doubt that the cruelties which were done by Mladic were preceded by cruelties from other Yugoslav peoples.
Naser Oric comes to mind.
Six years ago I wrote a blog about Mladic: http://xevolutie.blogspot.nl/2011/05/142-mladic.html
There is also a Voltaire article which dates from 2011:
I have visited the trial of Mladic once, around 2015.
It was nopt difficult for me to get the strong impression that the judge was not at all looking for the truth.
Worst of all is that Naser Oric was set free: he is guilty of nothing!
Where we can clearly hear him say in this secretly taken video recording that he is happy about all the villages with older Serb peoples who were killed.

He did roast the old people alive, hanging above a fire. Why? Oric: Because we do not have enough ammunition....
