His "truth" is merely opinion, and poorly supported at that. From I hear of Mr.McCain, he was the son of a wealthy man and got distinguishing remarks based on his father's reputation, but he did endure tortue, and denied early repartriation as he didn't want to leave his men behind. While you can question his ability as a soldier and what actions he carried out, the truth is he suffered terrible life long injuries for an ordeal he choose to prolong for his men. To me, that is heroic, and all that matters, bar nothing horrible popping up.
