Fear-Mongering Over New IAEA Iran Report Falls Flat

Try as they might, those who are pushing hard for a military attack on Iran under the guise of preventing Iran obtaining nuclear weapons are finding it impossible to whip up enough fear to overcome the media frenzy surrounding the home stretch of the Presidential Election season. Today’s biggest dose of fear-mongering is courtesy of Jodi Rudoren and David Sanger at the New York Times:

For Prime Minister Benjamin Netanyahu, the International Atomic Energy Agency on Thursday offered findings validating his longstanding position that while harsh economic sanctions and diplomatic isolation may have hurt Iran, they have failed to slow Tehran’s nuclear program. If anything, the program is speeding up.

But the agency’s report has also put Israel in a corner, documenting that Iran is close to crossing what Israel has long said is its red line: the capability to produce nuclear weapons in a location invulnerable to Israeli attack.

Despite Rudorin and Sanger claiming that Iran is “close” to “the capability to produce nuclear weapons in a location invulnerable to Israeli attack”, a closer examination of both data they present in the article and of the IAEA report itself shows that Iran’s “progress” toward a weapon is precarious at best.

For example, a chart in the Times article shows the proliferation of centrifuges at the Qom facility which is located inside a mountain and presumed to be immune from Israeli (but probably not US) bombs. The figure shows that the total number of installed centrifuges at this facility has increased steadily from 0 in September of 2011 to 2,140 this month. However, the same figure also shows that only 696 of those centrifuges are functioning and the number of functioning centrifuges has not changed over the course of the three reports issued in February, May and August of this year.

The claim that Iran’s program is “speeding up” also looks quite dubious in light of this report from Fredrik Dahl of Reuters: Read more

Persians Punk Photo Pretenders: Parchin Pretty in Pink

Detail from the photo carried in CNN’s story showing the pink tarp over the building said to contain the blast chamber.

In order to make the case for a military attack on Iran, those who advocate war need to show that Iran is engaged in developing a nuclear weapon. There will be a new IAEA report this week, and we already know that this report will try to whip up excitement around what is already known: Iran’s installation of additional centrifuges for enrichment of uranium to 20% has continued, and Iran now has increased its capacity for such enrichment. What press accounts of the enrichment situation will gloss over is the fact that IAEA inspectors are present at all of Iran’s enrichment sites and that all material is accounted for. That means that in order to accuse Iran of taking 20% enriched uranium and subjecting it to further enrichment to the 90%+ that is needed for weapons, one would have to postulate a secret site, unknown to IAEA inspectors, where Iran could take raw uranium ore all the way to weapons grade.

With the rogue enrichment route to a military attack unlikely to gain footing, war advocates also accuse Iran of other activities aimed at developing a nuclear weapon. A favorite target for those accusations is the military site at Parchin, where one particular building has been separated out and accused of holding a high explosives blast chamber where Iran is accused of carrying out research aimed at developing a neutron trigger device for a nuclear bomb. Despite a very thorough debunking of this theory by b at Moon of Alabama, where it was shown that the chamber was much more likely to be used in production of nanodiamonds than neutron triggers, the accusations continued. In May, George Jahn of AP provided ridiculous “proof” of work on a trigger device by publishing a cartoon (drawn from a real photograph!) and description of the chamber. These new allegations from Jahn even included a claim that there was a neutron detector on the outside of the chamber so that neutron flux from the explosions inside the chamber could be monitored. I showed that this allegation meant that if such work had been carried out, the steel chamber itself would have been made radioactive through the process of neutron activation. This radioactivity would be present throughout the thickness of the steel and therefore could not be removed by a surface cleaning.

Despite the fact that the steel chamber (and possibly even the structural steel of the surrounding building) would be radioactive in a way that could not be cleaned, we have for months been deluged with accusations that Iran is “cleaning” the Parchin site. After this process had gone on for some time, I began to describe it as a game of cat and mouse in which it appears that Iran is having quite a bit of fun at the expense of those who are making allegations about the Parchin site. The primary target of Iran’s pranks in Parchin is David Albright, of the Insitute for Science and International Security. Despite no known expertise in intelligence gathering by photo analysis (and that comment on lack of expertise comes from someone who previously was a CIA photo analyst) we have had multiple accounts from Albright of Iran “cleaning” the Parchin site to remove evidence of their work on a trigger device.

I have responded to most of Albright’s reports, but chose not to respond to his report of August 1, where he declared that Iran had finished its cleanup work at Parchin. That report appears to have been operational for only a brief period, however, as a report issued on August 24 shows images from August 15. In this new report, additional activity at Parchin has taken place and the suspect building is now draped with a tarp that is bright pink.

In keeping with the usual pattern for these accusations, CNN has breathlessly repeated Albright’s analysis. It hardly seems necessary to point out that the point I have been making all along still stands. The most important element of any inspection at Parchin will be the high explosive chamber itself. Iran cannot “scrub” it of neutron activation. That means that if sufficient neutron trigger work was carried out in the chamber to make it radioactive, Iran will need to remove and destroy the chamber. Whether there is a pink tarp over the building or not is irrelevant to the issue of whether the chamber still exists.

The only way Iran can top the comedic spectacle of the pink tarp is to paint the ground outside the building to mimic Albright’s yellow comment balloons and font with a note along the lines of “Please do not look at this building”.

I’m Confused. Are THESE Leaks Permissible, or Not?

As you read this Reuters story, remember that the House voted to mandate investigations into leaks that undermined Israel’s case for war against Iran and that the biggest new news in David Sanger’s reporting on StuxNet is that Joe Biden and others believed the Israelis set StuxNet free of Natanz. Leaks that inconvenience Israel’s hawks, you see, are bad, even if they serve US interests.

The Reuters story is a response to two reports in Ha’aretz yesterday that a new NIE–or maybe not an NIE but a top intelligence report–says Iran is closer to developing nukes than the US previously believed.

Defense Minister Ehud Barak confirmed on Thursday Haaretz’s report that President Barack Obama recently received a new National Intelligence Estimate report on the Iranian nuclear program, which shares Israel’s view that Iran has made significant progress toward military nuclear capability, and said that the report has raised the urgency of the issue.

Speaking on Israel Radio on Thursday morning, Barak said that there is a U.S. intelligence report “being passed around senior offices,” and that, as far as Israel knows, this report has brought the U.S. position over Iran closer to the Israeli position, and made the issue more urgent.

[snip]

Haaretz reported on Thursday that the National Intelligence Estimate report on Iran was supposed to have been submitted to Obama a few weeks ago, but it was revised to include new and alarming intelligence information about military components of Iran’s nuclear program. Haaretz has learned that the report’s conclusions are quite similar to those drawn by Israel’s intelligence community.

Not a single member of Congress called for a witch hunt into who leaked the NIE–or maybe not an NIE but a top intelligence report–to Israel and/or Ha’aretz.

Apparently, it’s okay to leak intelligence to Israel if it helps build a case (just in time to roll out a new product in September, I’ll note) for war, but not if it hampers Israel’s efforts to gin up a war. Is that the rule?

If so, what about this Reuters story?

In it, we have anonymous sources back in full force, refuting (sort of) those reports. Note the sourcing.

The United States still believes that Iran is not on the verge of having a nuclear weapon and that Tehran has not made a decision to pursue one, U.S. officials said on Thursday.

[snip]

But a White House National Security Council spokesman disputed the Israeli reports, saying the U.S. intelligence assessment of Iran’s nuclear activities had not changed since intelligence officials delivered testimony to Congress on the issue earlier this year.

“We believe that there is time and space to continue to pursue a diplomatic path, backed by growing international pressure on the Iranian government,” the spokesman said. “We continue to assess that Iran is not on the verge of achieving a nuclear weapon.”

[snip]

Another U.S. official said the United States regularly exchanges intelligence reporting with its allies, which would include Israel.

Apparently, Tommy Vietor (or someone sitting next to him) felt obliged to refute the reports, but would not do so on the record, not even to back his two sentence quote in the Reuters report. It’s okay for Ehud Barak, who was fed this intelligence either in normal intelligence sharing or alternately just handed the US the report in question and now is claiming that the report has been incorporated into the NIE (says a US official who seems determined to provide some explanation for this leak), to talk about leaked US intelligence on the record, but it’s not okay for the NSC spokesperson to do so.

It’s a new twist on the A1 cutout Dick Cheney used, I’m fairly certain: launder the leak through leaks to Israel, because no one in Congress or DC generally (except the FBI) gives a damn about leaks to Israel.

Whatever. I’m thoroughly confused. Am I right that the leak to Israel is considered acceptable but now the sources for the Reuters report will be targets of a witch hunt?

Taliban Destroy 22 Supply Trucks in Afghanistan: No “Protection” Money on Northern Route?

Google Map showing relative locations of Aibak and the Salang tunnel in Afghanistan. (Click on map for a larger view.)

When the flow of supply trucks through Pakistan into Afghanistan restarted earlier this month, I pointed out a report from the Express Tribune on the large amounts of cash paid to the Taliban as “protection” money. A detail in that report is that the protection money paid is to “Afghan Taliban and local militants who are active on the Pak-Afghan borders”.

Today, the Taliban have claimed responsibility for an attack that destroyed 22 NATO supply trucks, most of which were fuel tankers. The attack was in Aibak, in Samangan province. The screen capture of a Google map of the area shown here indicates that Aibak is only 117 miles from the northern opening of the Salang tunnel that is the key choke point on the “northern route” that NATO used for supplies while the Pakistan crossings were closed. Does today’s attack mean that the Taliban in the north of Afghanistan have now placed a marker indicating that protection money will have to paid to them as well? It is not clear whether they were paid protection money while the Pakistan route was closed and it has now stopped or if they are angling for a hefty protection fee when this route is used for evacuation of NATO equipment as the drawdown moves into its active phase soon.

Here is Reuters’ description of the attack:

 A bomb planted by the Taliban destroyed 22 NATO trucks carrying supplies to their forces in northern Afghanistan, the Taliban and police said on Wednesday.

Eighteen fuel trucks and four supply vehicles were parked in Aibak, the capital of Samangan province, when a bomb ripped through them, wounding one person, local police said.

“At 2 a.m. the mujahideen attacked the invader NATO trucks,” the Taliban said in a statement, referring to the wagons which had been driven from Uzbekistan to Afghanistan’s north.

The Taliban in this region have been flexing their muscle lately:

The trucks were attacked in the same province where prominent anti-Taliban lawmaker Ahmad Khan Samangani was killed on Saturday at his daughter’s wedding, in a suicide bomb attack that killed 22 other guests.

It will be very interesting to see if reports of protection money along the norther route begin to surface.

One more aspect of this attack bears watching. From the AP story on the attack as carried by Dawn:

 ”We put explosives on a fuel tanker. When it exploded, we fired on the trucks,” Taliban spokesman Zabiullah Mujahid told The Associated Press in a telephone call.

Sidiq Azizi, a spokesman for the province, said many tankers and semi-trailers caught fire after the bomb went off around 2 a.m.

By mid-day, heavy black smoke still poured from the Rabatak area of the province where the truckers had stopped to rest. Firefighters were spraying water on the burning vehicles.

”There was a big boom,” Azizi said.

”It’s possible that is was a magnetic bomb from insurgents. We are investigating.”

The referral to a magnetic bomb is interesting. Going back to the Reuters report:

Separately, police in neighboring Baghlan province said they had detained 10 suspected Taliban members with so-called magnetic bombs, which they were trying to attach to supply trucks.

Will NATO try to assert that the magnetic bombs are supplied by Iran? Recall that Iran was accused of using a magnetic bomb in India to attack an Israeli diplomat in reprisal for the presumed Israeli magnetic bombs that have been used to kill Iranian nuclear scientists. The US made accusations of Iran helping the Taliban back in 2010 but never provided conclusive evidence for the Sunni Taliban and Shia Iranian regime working together. Will the accusations resurface based on the magnets?

Iran’s Cat and Mouse Game at Parchin Continues; Albright Takes Bait Yet Again

After a disappointing ending to yesterday’s final session of the P5+1 talks in Moscow, we now must deal with even more of the cat and mouse game Iran is playing at Parchin. I have posted on this issue a number of times, so I won’t go back into the complete details of what is going on, but the primary issue here is that the West has accused Iran of carrying out work at the Parchin military site that is aimed toward developing a trigger for a nuclear bomb. Specifically, Iran is accused of using a high explosives chamber to research the use of uranium in high explosions to generate the neutrons needed to trigger a nuclear bomb. “Western diplomats”, aided by gullible reporters and especially by David Albright of the Institute for Science and International Security are now claiming that Iran is trying to scrub the site of evidence from this work.

The problem is that it is impossible to scrub evidence of this sort of work. As I showed in this post, if Iran actually carried out the work for which they are accused, the steel chamber where the explosions occurred and all of the structural steel in the surrounding building would be radioactive due to neutron activation. This would not be surface contamination of the steel but would be distributed throughout the entire thickness of the steel. Therefore, if Iran carried out the accused work, the only way to hide the evidence would be to destroy the steel tank and the building in which it is housed.

In a game of cat and mouse, Iran destroyed buildings nearby the building in which the steel tank is said to be housed and did extensive earthmoving work in outlying areas away from the building. Albright dutifully took that bait and said this work was evidence of cleansing activity and did not mention that the chamber and its surrounding building were still standing and should still carry all of the radioactive earmarks of the accused activity.

Today, Albright has taken the next round of bait offered up by Iran. More earthmoving activity is seen in new photos and there are even new puddles to go along with the first puddles Albright found.

Here is Albright’s description of the new activity: Read more

P5 +1 Talks Resume in Moscow With Iran Sanctions Set to Ratchet Up

The latest round of talks between the P5 + 1 countries and Iran on Iran’s nuclear technology are underway today in Moscow amid mixed signals on whether any progress is expected. There is significant pressure on Iran in these negotiations as the sanctions currently in place are already causing great difficulty and they are set to move to an even more restrictive level in two weeks if no diplomatic progress is made.

Iran’s Mehr News agency is running a story with the headline “Iranian nuclear negotiators not optimistic about Moscow talks” which paints a stark picture of prospects for the talks:

The quality of the interaction of the Western countries’ representatives in the nuclear talks with Iran coupled with the atmosphere prevalent in the Baghdad talks, a reluctance for preparatory and expert talks before the Moscow meeting, and no authorization to present effective proposals have almost eroded chances for a breakthrough in the talks which starts on Monday, our correspondent says.

The Iranian negotiators say the Western countries on the 5+1 group have reneged on the agreements made in the previous meetings. They also say if the Western countries repeat their previous statements the negotiations will “definitely fail”.

Iran has clearly favored Moscow’s “step by step” proposal since the beginning of the process, and that preference also appears in this article:

There is also no sign that the Western countries are committed to the “step-by-step” approach or any new proposals will be presented in the talks on Monday and Tuesday.

According to the “step-by-step” proposal, which was first revealed by Russian Foreign Minister Sergei Lavrov at the Moscow Embassy in Washington on July 12, 2011, Iran would take steps to increase cooperation with the International Atomic Energy Agency and those steps would be rewarded with a gradual easing of sanctions.

Almost out of nowhere, Joby Warrick’s article in the Washington Post, which mostly centers on the status of sanctions now in place against Iran and the new sanctions set to kick in soon provides a “step by step” reference at the end. In this case, it seems significant that the reference is attributed to a Western diplomat:

But the Moscow talks could bog down quickly if Iran persists in demanding immediate relief from Western economic sanctions in exchange for any downsizing of its nuclear ambitions, U.S. diplomats and Iran experts say. Obama administration officials have said they would oppose a significant easing of sanctions until Iran makes verifiable cuts that sharply restrict its ability to develop nuclear weapons.

“We need to see a step-by-step process, with the core issue being an agreement by Iran on 20 percent enriched uranium,” said a Western diplomat involved in preparations for the Moscow talks. Read more

Transcribing Obama Administration Iran Spin, Sanger Advances False “Breakout” Capability

Marcy will be along later to discuss the shiny thong thing aspect of David Sanger’s New York Times article where he was awarded today’s transcription prize by the Obama administration and allowed to “break” the story in which the US for the first time admitted its role in cyberwarfare against Iran’s nuclear program. What I want to concentrate on here is how in putting forward the cyberwarfare story, Sanger unquestioningly accepts the administration’s framing that Iran is just a short “breakout” away from having multiple nuclear weapons.

Consider this key paragraph:

These officials gave differing assessments of how successful the sabotage program was in slowing Iran’s progress toward developing the ability to build nuclear weapons. Internal Obama administration estimates say the effort was set back by 18 months to two years, but some experts inside and outside the government are more skeptical, noting that Iran’s enrichment levels have steadily recovered, giving the country enough fuel today for five or more weapons, with additional enrichment.

All Iran needs is “additional enrichment” for “five or more weapons”. That assumption is false on many levels. First, because Iran’s enrichment activities are closely monitored by onsite IAEA inspectors, any activity aimed at above the 20% level which is their current upper bound would be detected quickly. That statement is backed up even by David Albright, who has been busy fanning the anti-Iran rhetoric on the Parchin front. Adding further doubt to a rapid breakout of enrichment is that even in this same article, Sanger notes that Iran’s centrifuge technology is old and unreliable. Albright supports that observation as well, and notes that installation of additional capability has been slowed by technical issues that don’t seem related to cyberattacks.

The second major flaw in Sanger’s transcription above is that more than just “additional enrichment” is needed. The whole cat and mouse game at Parchin is playing out because in addition to enrichment of uranium to weapons grade, Iran will need technology for initiating the nuclear chain reaction that results in the weapon being detonated. Sanger makes no mention at all of this technical barrier for which there is no evidence that Iran has made an appropriate breakthrough.

Heck, the “enough uranium for five bombs” framing requires us to count the material enriched to only 3.5%. That makes it surprising the US and Israel aren’t claiming that Iran has enough uranium for an unlimited number of bombs if you count the uranium in the ground that they haven’t mined yet.

Roja Heydarpour, writing at The Back Channel, brings us this bit of reassurance from David Albright that any Iranian attempts at enrichment to weapons grade would be caught quickly: Read more

Parchin Game of Cat and Mouse Escalates: Razed Buildings, Earthmoving Probably Don’t Affect Controversial Chamber

For a brief period yesterday afternoon, initial news reports had me thinking that perhaps proof had finally emerged that Iran has indeed carried out work on a nuclear weapon and was taking actions in an attempt to hide the after-effects of that work. As new details emerged, however, it became more clear that an elaborate game of cat and mouse is being played out between Iran and those who accuse them of weapon development, but overall there still seems to be no conclusive proof that weapon development at the controversial Parchin site has been carried out.

That is a pattern that has played out several times now. “Diplomats” provide anonymous information to a reporter in Vienna on new accusations about nuclear weapon development work in Iran. The first version of the story put out by the reporter contains only a vague accusation but is delivered with a sensationalized headline suggesting that new and important evidence supports the conclusion that Iran is carrying out work at Parchin aimed at developing a neutron trigger device for a nuclear weapon . Subsequent expansion of the article reveals that the “evidence” is much weaker than initially portrayed and that technical details tend to contradict the accusations for the large part.

Until yesterday, that pattern had played itself out three times since March, each with George Jahn of AP playing the role of the reporter in Vienna. First, there was the claim in March that Iran was trying to clean the Parchin site to remove evidence of work on a trigger device. It took several weeks after the initial claim, but finally a satellite image purporting to show evidence of “washing” the building at Parchin was produced in early May when David Albright displayed satellite images showing puddles in the parking lot outside the suspect building. Of course, Albright’s claim of “washing” away the radioactivity is ludicrous, as traces would remain, especially if the wash water is simply allowed to pool in the parking lot of the building. Albright and Jahn did not give up, however, and Jahn subsequently came up with a cartoon depicting the chamber (it’s even the same color as the real chamber!). The huge hole in those accusations, though, is that if the accused neutron trigger work with uranium were indeed being carried out at Parchin, then the process of neutron activation would have resulted in both the structural steel of the chamber itself and most likely the structural steel of the building housing the chamber being radioactive throughout the thicknesses of the steel. This would mean that Albright’s claims that Iran could “cleanse” the chamber and the building by grinding and washing surfaces were impossible. Instead, in order to clean the site:

The only way that Iran would be able to hide evidence of work on a neutron trigger device at Parchin would be to dismantle and remove the entire chamber. It most likely would be necessary to raze the entire building as well, since the structural steel in the building surrounding the chamber also likely would have been made radioactive by the neutrons.

Jahn’s third sensational headline followed by less sensational details related to the finding of traces of uranium enriched to 27% rather than 20% at the enrichment site at Qom instead of at Parchin, but this still fits the overall pattern.

Another aspect of attempts to clean evidence of work with radioactivity is removal of the upper layers of soil.

Yesterday, Fredrik Dahl of Reuters took over George Jahn’s role as the reporter in Vienna to release a sensational headline only for the real story to fall short of the accusations (apologies to Jahn for my initial–now deleted–tweets on this revelation, which I attributed to him when I reacted first to the headline and only later noticed the story was from Dahl and not Jahn). I have counted at least five versions of Dahl’s story as it was updated through the day yesterday and this morning. Here is complete article as it appeared in its initial form: Read more

George Jahn Once Again Grants Anonymity for Dubious Iran Accusation

Just under two weeks ago, AP’s George Jahn released the infamous cartoon around which he built a dubious nest of mostly anonymous charges that Iran had conducted work toward developing a neutron trigger device for nuclear weapons, using an explosive containment chamber at the Parchin military site. Jahn further repeated anonymous claims from “diplomats” that satellite imagery showed activity claimed to be Iran “cleaning” the site to remove traces of radioactivity.

It is simply impossible to “clean” radioactivity from a steel chamber in which uranium has been used to generate neutrons, as the neutrons would result in making the entire thickness of the steel chamber radioactive, as I showed in this post. The only way that Iran would be able to hide evidence of work on a neutron trigger device at Parchin would be to dismantle and remove the entire chamber. It most likely would be necessary to raze the entire building as well, since the structural steel in the building surrounding the chamber also likely would have been made radioactive by the neutrons.

Since negotiations between Iran and the P5+1 countries will continue next month in Moscow, those who prefer a war with Iran now must find new areas in which to accuse Iran of weapons work. George Jahn dutifully stepped up to play his role in this process again today, granting anonymity to “diplomats” who make a vague accusation that Jahn dressed up into a highly sensational headline that is backed up by few facts and then rendered essentially meaningless when he goes further into the information. At the AP’s site, Jahn’s article carries the headline “APNewsBreak: Higher enrichment at Iranian site“. The Washington Post decided that headline wasn’t incendiary enough, and so their version reads “APNewsBreak: Diplomats say UN experts find enrichment at Iranian site closer to arms level“.

The story itself is quite short. It opens:

 Diplomats say the U.N. nuclear agency has found traces of uranium at Iran’s underground atomic site enriched to higher than previous levels and closer to what is needed for nuclear weapons.

Wait a minute. This whole thing is about “traces” of uranium enriched to a higher level. Missing from the entire article is any detail of how much material was found or to what level the uranium was enriched. The highest level of enrichment currently declared by Iran is 20%, which the press in the recent past has been describing as only a short “technical step” away from the the 90%+ needed for a nuclear weapon.

The next two paragraphs from Jahn basically render his entire story moot:

The diplomats say the finding by the International Atomic Energy Agency does not necessarily mean that Iran is secretly raising its enrichment threshold.

They say the traces could be left during startup of enriching centrifuges until the desired level is reached. That would be a technical glitch only.

So, in other words, these “diplomats” are doing their best to create a crisis over something that is a mere “technical glitch” and represents an insignificant amount of material. Of course, for those who only see the headline, especially the one on the Post’s website, the idea will have been planted that Iran is cheating on its declared enrichment program and secretly producing material that is ready to be placed into a weapon.

As I pointed out in this post, all of these incendiary press reports about Iran and uranium enrichment overlook a very important basic set of facts: Read more

Amano: Agreement With Iran Reached, “Will Be Signed Quite Soon”

It appears that the hopeful signals being sent out by Iran yesterday ahead of the visit by IAEA Director General Yukiya Amano have been followed through. Speaking to reporters after his return to Vienna this morning, Amano announced that Iran and the IAEA have reached agreement on how to move forward on inspection of Iran’s nuclear activities.

Of particular importance, Amano describes the agreement as part of a structured approach, which seems to fit Iran’s insistence that any agreement would lay out in advance the framework for how and where inspections are to take place. From Bloomberg:

“There was an important development on the structured approach document on which we have been working since January,” IAEA Director General Yukiya Amano said today in Vienna after returning from Tehran, where the deal was reached yesterday. “The decision was made to conclude and sign an agreement.”

The accord will be signed “quite soon,” Amano told journalists, without giving a date or details. The agreement comes as negotiators head to Baghdad for a second round of negotiations tomorrow over Iran’s nuclear program.

The New York Times has more key details, including the fact that inspection of the Parchin facility will be part of the agreement:

Mr. Amano’s visit to Tehran on Monday was his first to Iran since his appointment in 2009. Mr. Amano’s trip here, announced unexpectedly on Friday, was part of what diplomats in Vienna called an effort centered on persuading Iran to allow inspections of a site the agency suspects has been used for secret tests for triggering mechanisms that could be used in a nuclear weapon. Iranian officials have ridiculed those suspicions and contended that the site, called Parchin, was sufficiently inspected by the agency in 2005.

Diplomats in Vienna said an investigation of the Parchin site was “not the only game in town” in the negotiations on the so-called structured approach.”

Asked about the Parchin site specifically, Mr. Amano said: “I have raised this issue of access to Parchin and this issue will be addressed as a point of the implementation of the structured approach document.”

Significantly, the suggestions that Iran has attempted to clean the Parchin site have not made it into any of the articles I have seen announcing this agreement. Read more
