Serbia was plenty violent itself, and is hardly an innocent party.
As for "who started it first", that depends on how far back in time you want to go.
Like I said, BOTH sides have blood on their hands.
Kosovo is Serbian named and established, all the towns were Serbian named before the Albanians came. Kosovo was the center of Serbian culture and nobility during the Middle Ages. Albanians were brought in by the Ottoman Turks. They were a mountain people who were into theft and violence; they still have the primitive Code of Lek in parts of Albania.
Trying to equate legitimate forces of a sovereign nation with Islamic terrorists aided by both Al Qaeda and NATO is an example of moral blindness.
In 1998 KLA terrorists trained by NATO forces in Turkey and North Albania have started their rampage by killing Albanians who were loyal citizens of Serbia. KLA was murdering posmen, forrest rangers and policemen.
It was deliberate, to provoke police and army to respond in protection of their citizens.
For example, in an event leadign to Racak incident KLA ambushed police car and murdered one Albanian policeman.
Before NATO started bombing Serbia as KLA airforce in March 1999, approx. two thousand people were killed, majority of them Serbs and Albanians killed by KLA.
After the war, KLA murdered more than 1000 Serbs and more than 1000 Albanians. Add this 2000 to those KLA murdered before the war and you will get the true scope of terrorism in Kosovo, aided and abetted by NATO.
Your claim that "BOTH sides have blood on their hands." is not only factuyally incorrect, it is morally flawed. It is open support to terrorism.
"Both sides" are actually NATO and KLA who attacked Serbia in contravention of all international treaties.
You may be conservative but you are terrorist supporter as well. How that two go together, I can not tell for the life of me.
