I mention my personal history to try to inject a little reality into the garbling of Vietnam-era history that has accompanied the WikiLeaks release of the Afghanistan war logs. Last week the left and right reached a rare consensus. The war logs are no Pentagon Papers. They are historic documents describing events largely predating the current administration. They contain no news. They will not change the course of the war.

About the only prominent figures who found serious parallels between then and now were Ellsberg and the WikiLeaks impresario, Julian Assange. They are hardly disinterested observers, but they’re on the mark  in large part because the impact of the Pentagon Papers on the Vietnam War (as opposed to their impact on the press) was far less momentous than last week’s chatter would suggest. No, the logs won’t change the course of our very long war in Afghanistan, but neither did the Pentagon Papers alter the course of Vietnam. What Ellsberg’s leak did do was ratify the downward trend-line of the war’s narrative. The WikiLeaks legacy may echo that. We may look back at the war logs as a herald of the end of America’s engagement in Afghanistan just as the Pentagon Papers are now a milestone in our slo-mo exit from Vietnam.

What was often forgotten last week is that the Pentagon Papers had no game-changing news about that war either and also described events predating the then-current president. By June 1971, the Tet offensive and Walter Cronkite’s famous on-air editorial were more than three years in the past. The David Halberstam article that inspired “The Best and the Brightest” had already appeared in Harper’s. Lt. William Calley had been found guilty in the My Lai massacre exposed by Seymour Hersh in 1969. Just weeks before the Pentagon Papers surfaced, the Vietnam veteran John Kerry electrified the country by asking a Senate committee, “How do you ask a man to be the last man to die for a mistake?” Most Americans had long been telling pollsters the war was a mistake. By the time the Pentagon Papers surfaced, a plurality also disapproved of how Vietnam was handled by Nixon, who had arrived in office promising to end the war.

The papers’ punch was in the many inside details they added to the war’s chronicle over four previous administrations and, especially, in their shocking and irrefutable evidence that Nixon’s immediate predecessor, Lyndon Johnson, had systematically lied to the country about his intentions and the war’s progress. Though Nixon was another liar, none of this incriminated him. His anger about the leak would nonetheless drive him to create a clandestine “plumbers” unit whose criminality (including a break-in at the office of Ellsberg’s psychiatrist) would lead to Watergate. Had Nixon not so violently overreacted that June  egged on by Henry Kissinger and fueled by his loathing of The Times and the antiwar movement  the story might have ebbed. Yes, the Pentagon Papers were labeled “top secret”  as opposed to the Afghanistan war logs’ “secret” status  but, as Richard Reeves writes in his book “President Nixon,” some 700,000 people in and out of government had clearance to read “top secret” documents. Compelling as the papers were, they were hardly nuclear code.

The public’s reaction to the Afghanistan war logs has largely been a shrug  and not just because they shared their Times front page with an article about Chelsea Clinton’s wedding. President Obama is, to put it mildly, no Nixon, and his no-drama reaction to the leaks robbed their publication of the constitutional cliffhanger of their historical antecedent. Another factor in the logs’ shortfall as public spectacle is the fractionalization of the news media, to the point where even a stunt packaged as “news” can trump journalistic enterprise. (Witness how the bogus Shirley Sherrod video upstaged The Washington Post’s blockbuster investigation of the American intelligence bureaucracy two weeks ago.) The logs also suffer stylistically: they’re often impenetrable dispatches from the ground, in contrast to the Pentagon Papers’ anonymously and lucidly team-written epic of policy-making on high.
