The only thing that the article got wrong was that the number of dead on ALL (Serb and Albanian) sides in Kosovo was 2500 before the NATO Bombing -- the additional 7500 in Kosovo happened AFTER the NATO Bombing started, and doesn't count the thousands of Serbs who died elsewhere in Serbia as a result of the Bombing.
We killed -- or got killed -- far more people than died before the NATO Bombing, not to mention the several hundred thousand Serbs who were ethnically cleansed from Kosovo as a result.
