Then come out and say that no war crimes were committed by NATO during Allied Force and I'll consider the matter closed with you.
Further, I don't consider General Wesley Clark (Supreme Allied Commander of Europe - NATO) to be a "serviceman" Rather he's is (was) a "policy maker."

["Everybody's entitled to an opinion, regardless of whether it's informed or not."]
The SACEUR and Secretary General of NATO both hold "HEAD OF STATE" status, so as to be able to cut through red tape and contact anyone in the world in order to hold the Alliance together.
That, in my mind, puts General Clark above the level of "serviceman."
