The last general to fall on his sword over principle was probably AF CoS Gen Ron Fogleman when he quit over the Kobar Towers blame game. Guys like Hackworth, Olds, Day and the like would never make Major in today’s military. Suspect the only reason Robin Olds got his star was they didn’t know what else to do with him!
He was always a tough guy, a lot like Curtis Lemay. He was known as "RoboCinC". I wonder where he is today. He is too talented a personality to just disappear as he did during the Clinton years - but he did.
