There should be at least one leak like the Pentagon Papers every year.

In my estimation, there has not been in American history a more important leak than Edward Snowden's release of NSA material – and that definitely includes the Pentagon Papers 40 years ago.

We were young, we were foolish, we were arrogant, but we were right.

EVERY attack now made on WikiLeaks and Julian Assange was made against me and the release of the Pentagon Papers at the time.

Look, all administrations, all governments lie, all officials lie and nothing they say is to be believed. That's a pretty good rule.

I agree that there are things that should be kept secret.

But it is important always to keep in mind that the danger of harming humans is not connected only or even mainly with telling secrets, there can be great danger in keeping secrets.
