I started Sunday delivery of the Washington Post today. I was sitting here with my coffee and bagel, Meet the Press babbling on the TV, when I came across an odd little story, buried at the bottom of page A16, by Joby Warrick and Colum Lynch titled, U.N. Says Iran May Not Have Come Clean on Nuclear Past.

Unfortunately, it is difficult to explain what is new about the story, without some back-story.

On February 14, the United States made available the evidence from the so-called “laptop of death” to the IAEA regarding Iran’s pre-2003 nuclear weapons program. That briefing was covered, at the time, in articles by AP’s George Jahn and the New York Times David Sanger and Elaine Sciolino — though neither had much detail.

IAEA DDG for Safeguards Olli Heinonen then presented that evidence to the IAEA Board of Governors on Monday, February 25. AFP’s Simon Morgan and, again, AP’s George Jahn got details of this second briefing from some of the diplomats.

UK PermRep to the IAEA, Simon Smith, provided the “sound-bite” suggesting some weapons work might have continued after 2003:

“Certainly some of the dates that we were talking about, or that the secretariat was presenting in there, went beyond 2003,” Smith said.

Jahn really delved into the detail of the briefing. According to one diplomat, the post-2003 work may have been a review of past weaponization efforts:

She said it was unclear whether the project was being actively worked on in 2004 or the report was a review of past activities. Still, any Iranian focus on nuclear weapons work in 2004 would at least indicate continued interest past the timeframe outlined in the U.S. intelligence estimate.

A senior diplomat who attended the IAEA meeting said that among the material shown was an Iranian video depicting mock-ups of a missile re-entry vehicle. He said IAEA Director General Oli Heinonen suggested the component which brings missiles back from the stratosphere was configured in a way that strongly suggests it was meant to carry a nuclear warhead.

Now, today, Warrick and Lynch have a story based on notes from Heinonen’s briefing — a good bit of reporting — suggesting that the IAEA had collected “corroborating evidence” from the intelligence agencies of several countries (echo chamber warning) and presenting some new information.

Unfortuantely, the example of “new” information that Warrick and Lynch provide, pertains to documents “described studies on modifying Iran’s Shahab missile to allow it to accommodate a large warhead, which would detonate 600 meters above its target.”

This is not new. Those details were first reported in March 2005 by Carla Anne Robbins and later recycled by Robbins in July 2005 and then David Sanger and Bill Broad in the New York Times.

Indeed, that information, as Robbins reported in 2005, was briefed to the IAEA by Bob Joseph.

So, two questions: What was in the 2008 briefing that wasn’t in the 2005 briefing? And, what else is in those notes?
