Wiz, those were different times. No general would ever use such vulgar language in public that he really used. The word “Nuts” was only symbolic. No one would have expected to hear the general in that audio to say, “EFF You”.
I don’t know how old you are. Vulgarities like that would never be used by a general for public consumption. Even Patton’s vulgarities were never publicized to any great extent until after his death.
I prefer to believe the words from the man himself.
