They could claim whatever they want. We'd find them, arrest them, and give them a fair trial. If the Serbs had done that in Kosovo, there'd have been no 1999 bombing, no UNMIK or KFOR and not much to talk about on this thread.
Tough to make the SW USA to Kosovo analogy until we start sending our police, our Army, and our ex-cons in little private paramilitary bands on rampages of robbing, raping, killing and burning down the houses of Hispanic-Americans.
Just to make one thing clear.
Do you want to say that Serbian government sent "police, Serbian Army, and Serbian ex-cons in little private paramilitary bands on rampages of robbing, raping, killing and burning down the houses of Kosovo Albanians" and Haradinaj &Co. acted in self-defense?
If your answer is "YES" regardless of the established facts, think again.
Think of WACO,Tx and RUBY RIDGE when Clinton and Rhino sent what you described to kill American citizens who WERE NOT TERRORISTS like HAradinaj and Co..
Americans were killed for not obeying U.S. law., not because they committed the acts of terrorism.
