I cannot even believe you are making this argument. I have gone through this already with an old leftist by the name of Hobbes. I am really surprised to see you pushing this RS.
Think about what you are saying. If you were in a freaking POW camp do you believe your father would give one rat's ass if your release was going to be "used against him"?
Use your head. My father would have traded places with me, never mind given a shit what LBJ had to say about it.
The entire argument is absurd on its face.
So the code of conduct scenorio invented by the ambassador and backed by not much more than McCain's word seems more plausible? It's not against the code to give up military info or to help them in PR stunts when it does not involve your dad?
I really don't know what happened, but I find this deification of the War God McCain as somewhat disgusting.
It is largely POWs that have brought his detention into question. Why aren't they beyond question.
