there is a diference between bombing a SAM site that happened to be on top of a hospetal, and going into a village of 500 and leaveing a village of 200. you see when a force goes into an area and trys to kill an ethnicity it's called genocide, the term "genocide" was coined by Raphael Lemkin (1900–1959), a Polish Jewish legal scholar, in 1943, from the roots genos (Greek for family, tribe or race) and -cide (Latin - occidere or cideo - to massacre). now this word gets throughen around a lot any time a large number of people are killed, but it only realy applys when you are trying to kill off a genos, when you are trying to clense the earth of all jews, trying to kill all chatholics in Ireland, trying to kill all albanians in kosovo.
what NATO did to serbia was what is known as a 'war'. in a war you have two forces one trying to use force to ,well, force the other to follow there will, wars can be genocidal if the will of one side is that the other no longer exsist. however, NATO had specific terms, namely that serbia pulled out it's forces from kosovo and that milosovich was removed from power and turned in, NATO was not trying to purge the surbian genos from exsistance, but the serbs were trying to perge all Albainians from kosovo, the serbs had done similar things twice in the recent past, so can you blame NATO for being a bit twitchy?
as for the Albanians being terrorists, well it may be true that there were valid targets there, but the way the serbs whent about it was far worse, it'd be like us useing nukes in Iraq.
