re: So, was that war bad or not?
Not. It put a stop to genocide (or at least ethnic cleansing) and lead directly to Milosovic's overthrow. It ended a pattern of Serbian aggression in the former Yugoslavian republics. It was acheived completely with airpower alone and not one single american serviceperson was killed during the war. (I think a soldier might have stepped on a landmine since then.) There is no ongoing insurgency killing our forces there now. Sure the situation is far from perfect but that is the case in most parts of the world, including many parts of America.
