I think any NDA they signed after the fact would be of dubious legality or enforceability. The worst that could happen to them is a legal hassle, that would be far more damaging politically to Obama than it could possibly be worth. That NDA won’t hunt.
I pray you are correct.
NDA’s are treated pretty seriously though. I’d hate to see good people go down for speaking up. That is NOT how you run a squad. Everyone has their voice in planning, extraction, and reporting. How else is it going to work? You want zombies following orders to the letter? Or do you want intelligent, dedicated people who are willing to work on the fly to make every mission a success? Cutting corners seems to happen a lot, but, whatever works, right?
I pick the second every time.
