Ridiculous and false. War crimes are committed always by all participants in a war, there are no 'good guys'. But 1) Croatians did not have an extermination camp for Serbs, you can look up Srebrenica for that, 2) Croatians did not occupy a foreign Serbian city and proceed to torture and rape the local population, you can look up Vukovar for that, and 3) the Serbs started the whole thing, and now we are supposed to blame  NATO for helping to end the thing. Fuck that. 

Serbs still hate the west for the bombing instead of realizing that their own government was to blame. It is uncommon for a Serb to admit fault, they always play the victim.
