Your comment reminds me of a scene in the Rolling Stones' Altamont Concert film: Keith Richards is hanging out of his dressing room door and he answers a queston, "Yeah, we sold out, but it was for the money so that's okay! (laughter)" From Keith Richards, it was funny. A retired general claiming the military did not provide enough incentive to guard national secrets would also be laughable, but in a different sense.

Unrelated to the topic of this discussion and elsewhere in the film, Mick Jagger answers another question, "Am I satisfied? Sexually, yes. Philosophically, no." (Working from hazy memories here -- I last saw the movie in the 1970s, I think.)

The security agreements they signed are sufficient to guard national secrets. It has nothing to do with whether they go to work for Raytheon, the Saudi Defense Ministry, or Goodwill in their retirement, their compensation packages, etc.
