He actually makes a very good point. Milosevic was not that effective in dealing with Serbia’s enemies. He didn’t intervene militarily in Bosnia - which would have easily given the Serbs the victory. He pretty much betrayed the Serbs in Krajina. And he pulled his forces out of Kosovo when Russia began pressuring him to make nice with the United States.
We told the Serbs in Croatia that Belgrade would sell them out. They didn’t listen.
