Should there be a trial for Ratko Mladic?

There should be a general trial, not necessarily with specific defendants, but an impartial court should debate questions such as: Why is it that mainly Serbs are accused of "war crimes", when others distribute video clips of war crimes they (not Serbs) committed? Why aren't Serbs trusted to have established weather some people on their side committed or didn't commit war crimes? Why should such trials take place in one of those Western countries who don't grant their own descendants the right of return from South Africa, where farm murders frequently happen on a genocidal scale, where victims are of a certain ethnicity, where certain individuals and groups sing songs similar to what Nazis sang about Jews and what enemies of the Serbs sang and still sing about Serbs?
