From Errol Morris film.....


McNamara: I don't want to go any further with this discussion. It just opens up more controversy. I don't want to add anything to Vietnam. It is so complex that anything I say will require additions and qualifications.

EM: Is it the feeling that you're damned if you do, and if you don't, no matter what?

McNamara: Yeah, that's right. And I'd rather be damned if I don't.
