As to his guilt, read the transcripts--it's pretty obvious. And if you don't want to do that, let's hear from a couple close observers.
"We are both aware, as God knows, how much evil has been done [in Kosovo] in the course of the last year and especially in the last three months. The great part of the guilt lies with Milosevic."
-Bishop Artemije, senior representative of Serbian Orthodox Church, speaking for himself and Patriarch Pavle, head of the church, NYT, June 29, 1999.
W also has something to say:
"I welcome today's arrest of Slobodan Milosevic, the former President of Yugoslavia. His arrest represents an important step in bringing to a close the tragic era of his brutal dictatorship. Milosevic was responsible for great suffering throughout the Balkan region. He deserves to be tried for his crimes against the Serbian people. He also deserves to be tried for violations of international law...."
Are you truly so dim as to believe the pro-Serb posters supported Milosevic, marky-mark?
