I am afraid these retired/fired generals still trying to remind others about their past glory, and are trying to sell their books, or push for more interviews and knowledge sharing.
Kind of during family reunions you keep listening to your elders' stories where they describe something smart they used to do that even your kids have no clue what this conversation is all about. Something like lubricating the rings on your rotary phone... I know when my daughter found one in the basement 25 years ago, she had no idea what it was... and we described it as a phone... and she laughed and asked how can you put such a huge thing into your back pocket. She did not even asked about the cord...
