The second mistake was when he was too tough on the demonstrating students. Without outside intervention Yugoslavia sooner or later would have split harmoniously like Czechoslovakia and the Soviet Union, and there would be no mass of refugees. But the big powers had their own agenda, Serbia remained 'too big' for them, as Russia is now. In order to smash Serbia they 'strongly recommended' to the seceding provinces that they simply go away without negotiations. The NWO needed a pretext to invade Yugoslavia.
International law is dead and the powerholders behave more like Godfathers than like statesmen.
They make arbitrary decisions about who is too big and too strong and whose crimes are crimes, therefore they parcel Serbia now by taking away Kosovo. Vojvodina and Sandjak will follow and probably Montenegro. What will remain of Serbia will be filled up with a flood of Serbian refugees like an outgrown concentration camp without any humanitarian help from outside. The real goal of the Balkan wars was to reduce Serbia below its most basic denominator. World opinion and many Serbs didn't understand this.
