The International Atomic Energy Agency has released its latest report on Iran's suspected hidden nuclear program. The report surfaced yesterday. It was much anticipated, because advanced reporting suggested the IAEA had concluded definitively that Iran is engaged in a full-scale nuclear weapons program. Turns out the report does not say that. Still, the agency's report raises some very serious questions about what Iran is really doing. NPR's Mike Shuster has more.
MIKE SHUSTER, BYLINE: Maybe the most important message from the IAEA's latest report on Iran is that the evidence of hidden nuclear activity is growing and the questions are deepening. This was the most comprehensive of the IAEA's Iran reports, which go back eight years. And it's the most detailed.
The IAEA decided to make much more of its information public, based on scores of visits to nuclear facilities in Iran, to a thousand pages of documents, to intelligence provided by 10 other nations, to interviews with participants in the nuclear program. The cumulative evidence is designed to challenge Iran to provide some answers, says Muhammad Sahimi, who writes for the website Tehran Bureau.
MUHAMMAD SAHIMI: Most of the allegations about the possible military dimension of Iran's nuclear program are not really new and had been reported in the past in various reports of the IAEA and by the press. But what was new in it was that the agency provides what seems to be more evidence of past allegations.
SHUSTER: The report does come to the firm conclusion that Iran developed a secret structured nuclear weapons program before 2003. And it discloses details of the program's organizational structure in the Ministry of Defense and elsewhere. But that program was stopped abruptly after parts of it were made public, much to the dismay of Iran's leaders.
What the IAEA can't nail down is which components of that program continued or restarted after 2003, says David Albright, head of the Institute for Science and International Security.
DAVID ALBRIGHT: Parts of the program continued to receive funding. It was more hidden and mingled among civil and military research institutes, among universities. They suggested some progress was made on some of the bottlenecks or problems that hadn't been solved when the program was shut down. It shows some evidence of ongoing work, and in fact some work that could be going on now.
SHUSTER: Among the projects and technologies that the report says Iran has worked on are neutron initiators and detonators that can start an explosion in a nuclear device, a range of nuclear weapons components procured outside Iran, and computer modeling of nuclear explosions.
Most of these elements have been mentioned in previous IAEA reports. But there is one new element, says Muhammad Sahimi - a containment vessel which can be used to test high explosives that wrap around the uranium core of a nuclear device.
SAHIMI: The new report indicates that Iran may have continued in one form or another that experiment or that program. And it points to some satellite imagery that indicates that Iran has built a large steel container that is needed to do experiments with high explosives.
SHUSTER: The report is likely to disappoint those, some in the U.S. and in Israel especially, who expected it would provide proof that Iran is pursuing a full-scale nuclear weapons program. That is not the case, says Sahimi.
SAHIMI: No, it is not conclusive. And even the report keeps using alleged. Even the agency appears not to be 100 percent sure whether these reports are actually completely correct. And that's why it demands Iran to answer and explain certain aspects of the report that the agency report is not sure about.
SHUSTER: David Albright agrees.
ALBRIGHT: They don't have it all, but we're looking into a black box and trying to make sense out of a very secret program. And I think they've done a remarkable job.
SHUSTER: In the past, Iran has said the IAEA's allegations were based on forged documents. Now the evidence is much greater and much more difficult to dismiss.
Mike Shuster, NPR News, Washington.
INSKEEP: More difficult to dismiss, but still Iranian President Mahmoud Ahmadinejad has dismissed it today on state television. He said the agency discredited itself with its claims that Iran is looking to develop nuclear weapons. But he says his country will not retreat even a needle's width from its nuclear program.
