Plus, mass murders and other forms of ethnic cleansing also happened in Croatia
Of course, you failed to mention, or didn't know, that only 50 years before the conflict, the ethnic structure was:
1953: 65% Albanians vs 23% Serbs
In the eve of the 1999 bombing, it was:
1991: 82% Albanians vs 10% Serbs
And after the bombing and separation:
2011: 93% Albanians vs 1.5% Serbs
So, Albanians jumped from 65% to 93% and Serbs virtually disappeared from 23% to 1.5% in just 60 years. So, can you tell me - how's that explained?
