Miloshevich had no power outside of Serbia. The Yugoslav federation at that point was a bunch of disjointed sovereign states with a weak and barely functioning federal government. The sovereignty of the states went so far as to have ministers of foreign affairs and negotiating international agreements. How could Miloshevich, in Serbia, influence Slovenia or threaten it?
The non-Serb states habitually voted against Serbia (it was even known was the 'unprincipled coalition') and the consensual requirements (which the secessionists used to their advantage as long as it suited their agenda) for all decisions made federal government all but lame. The presidency was made up of individual representative states and two provinces in Serbia. Even when Miloshevich established a pro-Serb-voting block, with 'yogurt revolutions' in Montenegro, and Voyvodina, and political manipulation in Kosovo, it gave Serbia four votes -- Macedonia, Bosnia and Herzegovina, Croatia and Slovenia constituted the other four votes. So, at no time was Serbia in a position to dictate anything in SFRY under the 1974 Constitution.
Miloshevich was only an excuse for the other nationalists, primarily Croatians, to justify their own nationalist and secessionists goals. In fact, in the late 1960's Tito came down hard on the Croatian nationalists within his own communist ranks -- the period known as the "Croatian spring." That never ended; it was merely subdued. So, Miloshevich was a convenient excuse to rekindle it. Slovenes objected to Kosovo because they did not want their funds to go to Kosovo relief. Kosovo was always impoverished because Albanians were too busy making babies and living off federal aid. They simply thought Kosovo was not their problem. The reasons for secessions among these states take on a completely different meaning when you dig past what you read in the media and some well choreographed "official truths."
That mark guy is the definition of a troll. He doesn't care in the least about finding out the truth or learning about the Balkans. He only wishes to seak out his next opportunity to bash the Serbs. If you guys want to use his ignorant and hate filled posts as a spring board for helping to clear the record and help unmuddle the reality of the situation to some thoughtful lurkers, then fine. Just don't think you're going to change the mind of a troll with a less then admirable mission.
