Brennan On Drones: We've Been 'Judicious,' 'Disciplined' "I have been a strong proponent of trying to be as open as possible with these programs, as far as our explaining what we're doing. What we need to do is optimize transparency on these issues and at the same time optimize secrecy and the protection of our national security. I don't think that it's one or the other, it's trying to optimize both of them. What we need to do is make sure we explain to the American people what are the thresholds for action, procedures, the practices, the processes, the approvals, the reviews. The office of legal counsel advice is establishes the legal boundaries within which we can operate. It doesn't mean that we operate at those outer boundaries. And, in fact, I think the American people will be quite pleased to know that we've been very disciplined, very judicious, and authorities and these capabilities as a last resort."
