Unfortunately Lewis MacKenzie opinion is not relevant
Even during the war in Bosnia, Lewis MacKenzie was stating on many occasions that it was the Muslims who were breaking the cease fire agreements and bombing their own civilians to gain NATO support.
NATO promptly replaced him because he wouldnt follow NATO's anti Serb mantra.
Kosovo isn't a secret.
We all know what happened, and that the Muslims were the guilty party.
But unfortunately, Serbia isn't Russia.
