I have always believed that Johnson was complicit in the JFK killing. He hated the Kennedy brothers because they thought he was a country rube and rubbed his nose in it. Lady Bird, naive as she was, when telling of waiting on Air Force One at Love Field in Dallas, was quoted as saying, “Lyndon was so upset that he wanted to know if Bobby should be called to quote the precise swearing-in verbage.”
I thing LBJ really wanted to call Bobby to say, “Ha, ha.”
“...helped him establish his re-enslavement through the “Great Society”. The enslavement is for everybody now. “
All things (and history) considered, it hasn’t really taken that long at all.
