I'm not sure if that is "healing" or something else - like "Senate comity".
If John Kerry saw his error and was repentant about his mistakes, he could easily be forgiven. However, he still thinks what he does was right and defends it, despite all evidence to the contrary. This indicates, to me, he is either a dangerous or stupid man. I think he is the former.
I doubt that he could ever repent. He has lived the lies too long.
I don't know a single Vietnam vet who will even watch a Hanoi Jane movie nor do I know one who has any respect for John F'ing Kerry. I doubt that any would forgive him
