Its simple really, I dont think he would do one in his own back yard. I think he was motivated by ice-cold logic in Bosnia and Croatia.
The logic being that if you removed all the Croatians and Moslems from the parts of Bosnia and Croatia bordering Serbia, it would be easier to control those areas after the war, and later, annex those areas into Serbia.
Look at the Serbs in Croatia and the Serbs in Bosnia, look at the areas they wanted to control, look at what they did once they had achieved that control. You wont find any "lets conquer the entire nation and occupy it"-strategy, what you find is a "lets take these parts bordering Serbia and remove everything that isnt Serbian"-strategy.
In Kosovo, he doesnt need to do that, simply because Kosovo is an acknowledged part of Serbia. Then the Albanians start their own little war in Kosovo, aimed at independence naturally. For some unknown reason (i e Lewinsky and the need to shift focus from the presidents dick) the US decides to back this Albanian desire for a nation of their own.
They present a peace deal in that French meeting that is so outrageously insane it would make even Stalin blush. Then they say "accept this or we will attack". The Serbs say "uh..wtf are you on drugs? We sure as he** aint going to part with Kosovo, the cradle of our culture, the place we see as the birthplace of the Serbian nation"
The US says "do it now or face the consequences".
The Serbs say no. The US attacks. Its a f*cking outrage.
Its as if China would present the US with a "peace deal" giving New York and Michigan back to the Indians because the Chinese feel the Americans have been treating the Indians unfair. Then when the US refuses, the missiles come flying. You get the idea...Its like "who the he** are you to get involved in our domestic issues?"
Does that answer your question?
