Potus needs to apologize and show his humble side (kek).
He has to get in front of the tape. If the tape comes out before he apologizes, he's done.
Do it tomorrow. No mil props. Short and sweet. Take a few questions, take your lumps and go forward. Name a few of the heroes that died and are buried there and positive and impactful lives lived by an ancestor or two. Be humble. Ask that people look at your actions towards the mil over the past four years and not a few words in a poor attempt at humor.
When the tape is dropped, it won't leave a dent. It will be old news.
