The Pentagon Papers revelations dealt with a discrete topic, the ever-increasing level of duplicity of our leaders over a score of years in increasing the nation’s involvement in Vietnam while denying it. It revealed official wrongdoing or, at the least, a pervasive lack of candor by the government to its people.

WikiLeaks is different. It revels in the revelation of “secrets” simply because they are secret. It assaults the very notion of diplomacy that is not presented live on C-Span. It has sometimes served the public by its revelations but it also offers, at considerable potential price, a vast amount of material that discloses no abuses of power at all…

Mr. Ellsberg understood that some government documents should remain secret, at least for some period of time. Mr. Assange views the very notion of government secrecy as totalitarian in nature. He has referred to his site as “an uncensorable system for untraceable document leaking and analysis.”…

Mr. Assange is no boon to American journalists. His activities have already doomed proposed federal shield-law legislation protecting journalists’ use of confidential sources in the just-adjourned Congress. An indictment of him could be followed by the judicial articulation of far more speech-limiting legal principles than currently exist with respect to even the most responsible reporting about both diplomacy and defense. If he is not charged or is acquitted of whatever charges may be made, that may well lead to the adoption of new and dangerously restrictive legislation. In more than one way, Mr. Assange may yet have much to answer for.
