I will say that he did serve and that I give him chops for that. He did enter battle but How he left Nam well…debatable how he used a way to leave … but Cinderella did attend the ball.
He was a traitor. Not about his questionable purple hearts and pulling strings to get out of theater.
He met with the enemy negotiators in Paris to encourage them to win and not to compromise with the US.
He should have been in a jail cell, not the US Senate etc.
