Not only does he have night terrors, from what I have read, he has all his Vietnam "video" on a CD and watches it almost daily; and he usually makes reporters who come to interview him watch it with him.
Well, I will say what many of us are thinking. Besides being an evil, unscrupulous traitor and an opportunistic rich woman-marrying gigolo, the man is one hundred per cent certifiably insane. He is nutty as a fruitcake, gone round the bend, bats in the belfry, LOONY!!!
It's no surprise then that he is unable to let the traumas of Vietnam fade, if he's being reminded of it almost daily.
He's not a well man. "Unfit for Command"...!
Probably as a wistful reminder of the only halfway honorable thing he has done in his otherwise self-centered, useless existence.
He has lost touch with reality. It can now be said Kerry is thinks he's Norma Desmond. "I'm ready for my close up Mr. Moore." What a jerk!
