If anyone has any illusions about there being "Good guys" and "Bad Guys" in this conflict they should read General Rose (one time head of UNPROFOR in Bosnia). The blatant exploitation and misuse of UN "Safe havens" by all factions to descredit the other side or to gain military or political advantage is incredible. Nor were/are any of the factions above firing on their own civilians and blaming it in some one else.
I think there is now a general consensus in NATO that the air action has facilitated the "Ethnic cleansing" of Kosovo rather than halted it. But the longer this policy is continued, the harder it is for the polititians to admit they were wrong and change.
Incidentally, Shambles, purely at the level of semantics, I'm not sure I agree with you about ethnic cleansing. To me there is a lot of difference between clearing all of group X out of an given area, even by force, and the deliberate attempt to exterminate all members of Group X. Of course the former may lead to the latter, but that doesn't alter the difference in intent.
