It seems that you and about everyone else have a different take on this. I got the impression from listening to the father that he was being extremely careful as to what he was saying so as not to appear traitorous to the nation at large and yet relay some sort of message to his son and possibly others.
I think many have a different take on this because recent statements by Bergdahl Sr have been inconsistent with everything else up until now.
I totally agree, those parents were being super careful what they said, and there was a reason for that, and I don’t know what it was.
