Being a war veteran does not confer eternal respect nor does it shield anyone from disrespect or criticism. Hagel actually did serve honorably in VN, but he is not deserving of any respect for what he is as a senator. Benedict Arnold was a true hero in a major revolutionary war battle but was a true traitor in the end.
