What's Not in the IAEA Reports by Peter Casey

What's NOT in the
IAEA Iran Reports
by Peter Casey

Peter Zimmerman carries august credentials. He is a nuclear physicist. He has degrees from Stanford in experimental nuclear and particle physics. He was the top scientist for arms control at the State Department for a number of years. He later served as chief scientist for the Senate Foreign Relations Committee. He has written scores of papers on nuclear arms and arms control. He is currently emeritus professor of science and security at King's College in London. All in all, he sounds like someone who knows about nuclear technology, including nuclear weapons, and has the time to think carefully about anything he might write on the subject.

Or so you would think. But on July 6, 2008, Zimmerman published an opinion piece in the Boston Globe entitled "Time for Iran to Face More Sanctions," a screed that badly misuses the International Atomic Energy Agency's May 2008 report on its monitoring of Iran's nuclear power activities. In his piece, which was later republished in the International Herald Tribune, Zimmerman blatantly tries to terrify Americans about an Iranian nuclear menace that does not exist, may never exist, and poses no realistic threat whatsoever to the United States in any case. His commentary is also solid evidence that the New York Times, which owns both the Globe and the Tribune, is intent on once again disseminating the same sort of nonsense that facilitated a "case" for the Iraq invasion.

Zimmerman asserts that the IAEA has "recently reported that it has questions that Iran refuses to answer":

"Why is Iran using high explosives to implode a hemispherical shell of heavy metal? The only known use for such tests is to perfect a lightweight nuclear bomb.

"Why is Iran developing the kinds of detonators needed in an atomic weapon?

"Why is Iran designing, or redesigning, a ballistic missile warhead so that it can contain a nuclear weapon?"

This appears to be a deliberate attempt to spread multiple deceptions.

First, Zimmerman falsely depicts the IAEA's "reported questions" as relating to matters of fact. As the report itself makes clear, the questions relate to allegations based on what the IAEA calls the "alleged studies" – documentation found on a laptop computer purportedly obtained by U.S. intelligence agencies in mid-2004. (The bona fides of these laptop documents, whose origin is as murky as the infamous "Niger yellowcake" forgery, remain in substantial doubt, but that is a whole different story.)

Zimmerman also fails to disclose that the IAEA report states that "it should be emphasized … that the Agency has not detected the actual use of nuclear material in connection with the alleged studies" (IAEA Gov/2008/15 at paragraph 28 [.pdf]). The immediately preceding board report was even more explicit: "[I]t should be noted that the Agency has not detected the actual use of nuclear material in connection with the alleged studies, nor does it have credible information in this regard" (emphasis added; IAEA Gov/2008/4 at paragraph 54 [.pdf]).

Unfortunately, in Zimmerman's editorial, the issue is not whether Iran is doing or has done any such things. It is "why" it is doing them. It would be one thing for Zimmerman to state that he thinks that the uncorroborated "laptop" allegations are fact. What he thinks probably would have little likelihood of terrorizing most newspaper readers. But by misinforming readers that the IAEA itself considers these circumstances established fact, Zimmerman fortifies both the credibility and the impact of the lie.

Second, Zimmerman misleadingly indicates that the IAEA report describes questions about multiple, ongoing activities that can only relate to nuclear weapons. For example, he asserts that Iran is "using high explosives to implode a hemispherical shell of heavy metal" whose "only known use" is for a "nuclear bomb." But the IAEA report actually states, "A second aspect [of the alleged studies] concerns … the testing of at least one full-scale hemispherical, converging, explosively driven shock system that could be applicable to an implosion-type nuclear device" (emphasis added; IAEA Gov/2008/15 at paragraph 17).

An allegation, based on unauthenticated documents, that refers to a test that could have been applicable to a nuclear device is not the same as a fact regarding ongoing tests for nuclear devices. But even if Zimmerman had missed the nuance between that which may have been and that which is, the IAEA report goes on. "It should be noted that the Agency currently has no information … on the actual design or manufacture by Iran of nuclear material components of a nuclear weapon or of certain other key components, such as initiators, or on related nuclear physics studies" (emphasis added; IAEA Gov/2008/15 at paragraph 24). A person of Zimmerman's background and education surely ought to recognize that treating "no information" about X as proof of X is not very good reasoning.

It is possible that Zimmerman's "hemispherical shell of heavy metal" was a reference to the so-called "uranium metal document," which reportedly describes procedures for converting "yellowcake" into uranium metal and casting it into hemispheres. Gareth Porter recently reported that in January 2005, IAEA inspectors stumbled across this document gathering dust in some old files that Iran had let them rummage through. According to the IAEA, Iran claimed that in 1987 it had received the document, unsolicited, from Pakistan when it acquired centrifuge enrichment components and related documentation (IAEA Gov/2007/58 at paragraph 25 [.pdf]). Pakistan confirmed to the IAEA that it possesses an identical document (IAEA Gov/2008/15 at paragraph 24). And the IAEA has seen "no indication of any [uranium metal conversion] and casting activity in Iran" (IAEA Gov/2007/58 at paragraph 25). If Zimmerman had the "uranium metal document" in mind, his exaggerations are even wilder.

Zimmerman's assertion that the report states that "Iran refuses to answer" IAEA questions is grossly misleading. As documented in every single IAEA board report since the laptop allegations first surfaced, Iran has consistently and adamantly answered many of the allegations by describing them as baseless and fabricated. In addition, it was only in February 2008 that the U.S. gave the IAEA permission to show any of the documents to Iran to enable it to respond (IAEA Gov/2008/4 at paragraph 37). The U.S. further manipulated the IAEA's efforts by providing "much of this information [to the IAEA] only in electronic form" and "not authorizing the [IAEA] to provide copies to Iran" (IAEA Gov/2008/15 at paragraph 16). The U.S. even refused to give the IAEA itself copies of some material. For example, the U.S. did not let the IAEA have copies of key documents concerning the "ballistic missile warhead" for a "nuclear weapon" Zimmerman refers to. The agency was "therefore unfortunately unable to make them available to Iran."

Iran's declination to respond to allegations based on documents it has never been shown, or has only been allowed to peek at, may qualify as a "refusal" to answer. But Zimmerman's failure to mention this circumstance that at least partly explains a "refusal to answer" is incredibly misleading.

Moreover, the IAEA report discloses that Iran has in fact specifically "answered" questions that Zimmerman claims it has "refused to answer," such as "Why is Iran developing the kinds of detonators needed in an atomic weapon?" The "detonators" (exploding bridgewire detonators) were for civilian and conventional military activities, according to Iran (IAEA Gov/2008/15 at paragraph 20). More generally, Iran has told the IAEA that documentation it was permitted to look at was not authentic and had been fabricated. Nevertheless, it "did not dispute that some of the information contained in the documents was factually accurate, but said that the events and activities concerned involved civil or conventional military applicants" (IAEA Gov/2008/15 at paragraph paragraph 18). The report also noted that Iran continued to respond to questions posed by the IAEA.

Zimmerman's piece is seriously misleading in other important respects. He claims that Iran "has 320 tons of uranium hexafluoride [UF6] gas to feed its centrifuges, enough for almost 100 bombs, but not for even a fraction of one reactor refueling operation." What he does not mention is that "all of [the UF6] remains under [IAEA] containment and surveillance" (IAEA Gov/2008/15 at paragraph 9). He also fails to inform readers that:

* Without enrichment, 320 "tons" of UF6 is no more dangerous than 320 tons of silly putty.
* Since it began to enrich uranium, in February 2007, Iran has fed 3,970 kilograms, or less than four metric tons, into enrichment cascades (IAEA Gov/2008/15 at paragraph 2).
* To get fissile material, uranium must be enriched to consist of 90 percent U-235. Iran's enrichment levels, however, have never exceeded 4.7 percent U-235, a level that could only be consistent with producing nuclear electricity (IAEA Gov/2008/15 at paragraph 5). Iran is scarcely "well on is way" to "mastery" of U-235 production, despite Zimmerman's claim.
* As have all of its prior reports, the IAEA's May report states: "All nuclear material [at the two Iranian enrichment facilities] remains under Agency containment and surveillance" (IAEA Gov/2008/15 at paragraph 4).

Zimmerman also contends that Iran's current plans for enrichment are "too small … to provide fuel for a nuclear power program of any consequence," but big enough to enable it to build "twice as many nuclear weapons a year … than they otherwise could have done," providing further evidence that "it is apparent that the real purpose of Iranian enrichment is to provide fuel for weapons, not reactors." This is specious reasoning. Iran's program is R&D. Laying out plans to construct the Taj Mahal before you know whether you can build a hot-dog stand wouldn't make much sense. Despite its simplicity, moreover, Zimmerman's observation somehow has escaped the IAEA's attention. As recently as May 20 of this year, Mohammed ElBaradei, the head of the IAEA, stated, "We haven't seen indications or any concrete evidence that Iran is building a nuclear weapon and I've been saying that consistently for the last five years."

Apparently, ElBaradei does not share Zimmerman's Cheney-esque logic that the possibility that Iran may intend to develop nuclear weapons is evidence that it intends to develop them. And can there be any doubt that, had Iran's current plans been big enough (or when they become big enough) in Zimmerman's opinion to embrace a nuclear power program "of consequence," he would be one of the first to claim that those plans evidence Iran's intent to create even greater multiples of weapon-production capacity?

On Aug. 14, 2003, the Washington Post published an opinion piece in which Zimmerman judiciously observed that "[a]vailable evidence demonstrates that Saddam Hussein … lacked a serious nuclear weapons program in 2003. And if Mr. Bush had not held out the threat of Iraqi nuclear weapons 'within months,' it is doubtful that Congress would have given him a blank check. How can one conjure up a benign explanation for the president's assertions?" The essay concluded that "[t]he next time Bush wants to use armed force to preempt or prevent an attack on this country, he will have to prove his case far more completely than before. [The president] of the United States [has] forfeited the benefit of the doubt."

Zimmerman's recent Globe commentary concludes that "If Iran begins enriching uranium to weapons grade on an assembly-line basis, it could transfer this material to groups such as Hezbollah and Hamas, which might fabricate low-technology nuclear explosives. These would probably have yields nearly as high as the bomb that destroyed Hiroshima."

If. Could. Might. Nuclear weapons. Assembly line. Hezbollah. Hamas. Hiroshima. Is it possible that this agitprop could have been written by the same man who wrote in August 2003 that "The president's principal argument for going to war – to prevent a 'smoking gun that would appear as a mushroom cloud' – was based on bad intelligence that was misused while good intelligence was ignored"?

Over the past five years, Peter Zimmerman appears to have taken leave of his good judgment. He now wants to persuade readers to take leave of their own. Don't. Ask the question the Zimmerman of August 2003 demanded: Is there a reason to use armed forces against Iran "to preempt or prevent an attack on this country?" And don't give those who say "yes" the benefit of any doubt.

The IAEA's reports are available on its Web site in the section "IAEA and Iran in Focus." None of them are more than nine or 10 pages. Despite their subject matter, they are written in reasonably plain English. Even if it takes a little extra effort to figure them out, that effort is essential.

There is no sign that Washington and Israel will relent any time soon from their zealous campaign to foment war with Iran. It is no time to accept at face value the media's distorted descriptions of the IAEA's work. It is no time to buy into the reckless scaremongering over the Iranian nuclear "threat" from "experts" like Zimmerman.

It is every American's civic duty to read and understand the IAEA reports themselves. If we do, Washington just might not be able to get away with another fraudulent casus belli.

IAEA is not in the business of identifying nuclear weapons activities (under the safeguards agreement with Iran), and so it is not allowed to say that Iran *is* involved in weapons-related activities. Mel doesn't like me to argue from "authority", so I won't. I will argue from experience. I've been around the weapons business since 1959, one way or another, and held design clearances since 1984. I've also studied a lot of metal forming processes while researching nuclear proliferation for the US government. Let me state categorically: I know of no use for high explosive implosion of spherical shells of heavy metal except in fission nuclear weapons. Period. If Mr. Casey knows of a benign explanation, he owes it to us to tell us what it is.

A person of Zimmerman's background and education surely ought to recognize that treating "no information" about X as proof of X is not very good reasoning.
Note that he's tossing initiator research at me. Well, Iran has learned how to extract polonium, the crucial radioactive material in a World War II type of initiator. Perhaps they have some defectors to poison, I don't know. But note that I did not state anything about "key components" such as initiators. They're so trivial to make (or to adapt from oil well logging instruments), that Iran need not play that game yet. Anyway, I didn't discuss such manufacture, because I don't think Iran is yet at the stage of needing to manufacture components. The US went from its first tests of implosion in the summer of 1944 to a completed design for Fat Man in February of 1945. And that was in an era when nobody really knew if nukes worked.

I did not have the "uranium metal document" in mind. It is true that the Pakistanis confirmed that they had an identical document. That makes me think that the Pakistanis sold or gae the technology to Iran.

Sorry. The allegations are not "baseless and fabricated." They are well documented by IAEA. Hell, to believe that the Iranians answered the allegations you have to believe that the Iranians are telling the truth, when their entire response to IAEA has been one of obfuscation and evasion. Of course we only could give the IAEA the docs in electronic form; that's how we got them. That's, in any event, how I would want them.

The reason we did not furnish the documents in detail to the IAEA and Iran is quite simple: they contain weapons details, and the IAEA (let alone Iran) is not allowed to receive that information.

Suspicious little me. Exploding bridge wire detectors have some civilian applications, but not many.

True indeed. Iran is building enrichment plants which are capable of enriching the UF6 either to fuel grade or weapons grade. But, umm, don't give your kids UF6 instead of silly putty. It's awfully corrosive and toxic.

I think Mr. Casey is being deliberately obtuse here, and certainly misleading. The amount of material fed to the cascades to date is no measure of what could be fed later. Uranium-235 is fissile at any enrichment; that's a function of the nuclear structure, not the amount, but only a physicist would care. Mr. Casey picks a figure of 90% at which uranium is "fissile;" I think he means an enrichment at which the material is useful in nuclear explosives. He is wrong.

In theory, but not in practice, one can get an explosive chain reaction from 7% material. At 20% Eugene Wigner told me decades ago *he* could build a bomb but, "Peter, you couldn't." I concur completely, and the bomb would be enormous. But 90% is not the threshold for a useful nuclear weapon. The threshold is much lower, but I am not allowed even to hint. But you may well find information in the open literature that points at the actual enrichment in the Hiroshima bomb. An implosion system could do with lower enrichment and still be practical.

Casey also doesn't understand the physical process of enrichment -- that's clear. The amount of work that goes into enriching uranium is measured in an exotic quantity called Separative Work Units, or SWU (pronounced "swoo."). It should be clear that if you start with natural uranium containing 0.7% U-235, and if you separate that out, tossing away the useless U-238, to reach 4.75% concentration you have done a lot of "separative work". Indeed, by the time you reach 4% you have done MORE than half of the separative work needed to reach 90% U-235. So it is perfectly factual that Iran is well on its way to mastery of the production of weapons quality HEU. And, of course, a stockpile of 4.7% uranium can be reinserted into a centrifuge cascade and quite quickly further enriched to, say, 90%.

Ah yes, the old R&D excuse. Folks you have to ask why a country rich in oil, very rich, and which has been offered all the 4.7% uranium it needs for all the reactors it might ever build at market prices or below wants to invest billions in mastering an exotic technology that will produce reactor fuel at considerably higher prices than market rates.

Let us repeat; ElBaradei's organization is not empowered to look for weapons-related activities. It is only allowed to ask Iran to prove that all of its uranium remains under seal and hasn't been hidden away. At the moment that is true; there have been no diversions of uranium. The only time IAEA was allowed, told, to look for weapons-related activities was when the Iraqi program was taken down in 1991-98. Since Iran has disavowed its "additional safeguards protocol," the IAEA can't even make snap inspections.

And can there be any doubt that, had Iran's current plans been big enough (or when they become big enough) in Zimmerman's opinion to embrace a nuclear power program "of consequence," he would be one of the first to claim that those plans evidence Iran's intent to create even greater multiples of weapon-production capacity?
Would I? Casey is wrong. I maintain, correctly, that for more than a decade before 2002 Iran surreptitiously engaged in a uranium enrichment progrm in violation of its safeguards obligations. If that program had been exclusively peaceful and commercial, why didn't the Islamic Republic declare it at the inception? If the plans for Natanz had been for about 100,000 or 150,000 P1-class centrifuges, I would have believed that, against economic rationale, Iran was planning to enrich its own uranium for Bushehr because the demand would have matched the output, more or less. It was the small size of the plant that gave away the game. Why? Because Iran would have no need to produce the hundreds of bombs a year that 150,000 machines would allow. But it could keep its reactors going. Oh, just by the way, Iran has no need to enrich uranium for Bushehr: its contract with Russia includes guaranteed fuel services and the removal of spent fuel.

Why yes indeed, the 2 were written by the same man. Casey is unable to understand that the data input to my brain are different now than in 2003. In 2003 I knew that the Iraqis had absolutely no capability to enrich or reprocess uranium and tht the weapons scientists had been scattered to other projects. In 2008 I know that the Iranians are building a weapons-program sized enrichment plant and have concentrated their scientists. They've also taken the first experimental steps towards design of a good weapon -- something that Iraq never did! Indeed, the Iraqis were peculiarly incompetent according to information provided to me by all 3 of the men who claim to have been directors of the program (of course, those guys didn't say they were incompetent; their answers to our questions in interviews demonstrated it).

> Peter Zimmerman carries august credentials. He is a nuclear physicist. He has degrees from Stanford in experimental nuclear and particle physics. He was the top scientist for arms control at the State Department for a number of years. He later served as chief scientist for the Senate Foreign Relations Committee. He has written scores of papers on nuclear arms and arms control. He is currently emeritus professor of science and security at King's College in London. All in all, he sounds like someone who knows about nuclear technology, including nuclear weapons, and has the time to think carefully about anything he might write on the subject.
>
> Or so you would think. But on July 6, 2008, Zimmerman published an opinion piece in the Boston Globe entitled "Time for Iran to Face More Sanctions," a screed that badly misuses the International Atomic Energy Agency's May 2008 report on its monitoring of Iran's nuclear power activities. In his piece, which was later republished in the International Herald Tribune, Zimmerman blatantly tries to terrify Americans about an Iranian nuclear menace that does not exist, may never exist, and poses no realistic threat whatsoever to the United States in any case. His commentary is also solid evidence that the New York Times, which owns both the Globe and the Tribune, is intent on once again disseminating the same sort of nonsense that facilitated a "case" for the Iraq invasion.


\/\/ If Iran gets nuclear weapons, it will pose a threat to the US because of its threats to US interests in the Gulf and as far north-west as Rome.

> First, Zimmerman falsely depicts the IAEA's "reported questions" as relating to matters of fact. As the report itself makes clear, the questions relate to allegations based on what the IAEA calls the "alleged studies" – documentation found on a laptop computer purportedly obtained by U.S. intelligence agencies in mid-2004. (The bona fides of these laptop documents, whose origin is as murky as the infamous "Niger yellowcake" forgery, remain in substantial doubt, but that is a whole different story.)


\/\/\/ My sources at IAEA do not dispute the authenticity of the laptop documents. Indeed, I got an e-mail on my article from the personal assistant to ElBaradei. All my source could say was that I wasn't helpful because I didn't support the Director General's "freeze for freeze" initiative. He did not take issue with anything substantive.
>

> Zimmerman also fails to disclose that the IAEA report states that "it should be emphasized … that the Agency has not detected the actual use of nuclear material in connection with the alleged studies" (IAEA Gov/2008/15 at paragraph 28 [.pdf]). The immediately preceding board report was even more explicit: "[I]t should be noted that the Agency has not detected the actual use of nuclear material in connection with the alleged studies, nor does it have credible information in this regard" (emphasis added; IAEA Gov/2008/4 at paragraph 54 [.pdf]).


\/\/\/ In this sense "nuclear material" refers to enriched uranium. Iran, as of now, does not have any useful quantity of enriched uranium. It does have natural uranium metal which was used.
>

> Unfortunately, in Zimmerman's editorial, the issue is not whether Iran is doing or has done any such things. It is "why" it is doing them. It would be one thing for Zimmerman to state that he thinks that the uncorroborated "laptop" allegations are fact. What he thinks probably would have little likelihood of terrorizing most newspaper readers. But by misinforming readers that the IAEA itself considers these circumstances established fact, Zimmerman fortifies both the credibility and the impact of the lie.
>
> Second, Zimmerman misleadingly indicates that the IAEA report describes questions about multiple, ongoing activities that can only relate to nuclear weapons. For example, he asserts that Iran is "using high explosives to implode a hemispherical shell of heavy metal" whose "only known use" is for a "nuclear bomb." But the IAEA report actually states, "A second aspect [of the alleged studies] concerns … the testing of at least one full-scale hemispherical, converging, explosively driven shock system that could be applicable to an implosion-type nuclear device" (emphasis added; IAEA Gov/2008/15 at paragraph 17).

\/\/
IAEA is not in the business of identifying nuclear weapons activities (under the safeguards agreement with Iran), and so it is not allowed to say that Iran *is* involved in weapons-related activities. I've been around the weapons business since 1959, one way or another, and held design clearances since 1984. I've also studied a lot of metal forming processes while researching nuclear proliferation for the US government. Let me state categorically: I know of no use for high explosive implosion of spherical shells of heavy metal except in fission nuclear weapons. Period. If Mr. Casey knows of a benign explanation, he owes it to us to tell us what it is.

>
> An allegation, based on unauthenticated documents, that refers to a test that could have been applicable to a nuclear device is not the same as a fact regarding ongoing tests for nuclear devices. But even if Zimmerman had missed the nuance between that which may have been and that which is, the IAEA report goes on. "It should be noted that the Agency currently has no information … on the actual design or manufacture by Iran of nuclear material components of a nuclear weapon or of certain other key components, such as initiators, or on related nuclear physics studies" (emphasis added; IAEA Gov/2008/15 at paragraph 24). A person of Zimmerman's background and education surely ought to recognize that treating "no information" about X as proof of X is not very good reasoning.


\/\/ Iran has learned how to extract polonium, the crucial radioactive material in a World War II type of initiator. Perhaps they have some defectors to poison, I don't know. But note that I did not state anything about "key components" such as initiators. They're so trivial to make (or to adapt from oil well logging instruments), that Iran need not play that game yet. Anyway, I didn't discuss such manufacture, because I don't think Iran is yet at the stage of needing to manufacture components. The US went from its first tests of implosion in the summer of 1944 to a completed design for Fat Man in February of 1945. And that was in an era when nobody really knew if nukes worked.
>

> It is possible that Zimmerman's "hemispherical shell of heavy metal" was a reference to the so-called "uranium metal document," which reportedly describes procedures for converting "yellowcake" into uranium metal and casting it into hemispheres. Gareth Porter recently reported that in January 2005, IAEA inspectors stumbled across this document gathering dust in some old files that Iran had let them rummage through. According to the IAEA, Iran claimed that in 1987 it had received the document, unsolicited, from Pakistan when it acquired centrifuge enrichment components and related documentation (IAEA Gov/2007/58 at paragraph 25 [.pdf]). Pakistan confirmed to the IAEA that it possesses an identical document (IAEA Gov/2008/15 at paragraph 24). And the IAEA has seen "no indication of any [uranium metal conversion] and casting activity in Iran" (IAEA Gov/2007/58 at paragraph 25). If Zimmerman had the "uranium metal document" in mind, his exaggerations are even wilder.

\/\/
I did not have the "uranium metal document" in mind. It is true that the Pakistanis confirmed that they had an identical document. That makes me think that the Pakistanis sold or gave the technology to Iran.
>

> Zimmerman's assertion that the report states that "Iran refuses to answer" IAEA questions is grossly misleading. As documented in every single IAEA board report since the laptop allegations first surfaced, Iran has consistently and adamantly answered many of the allegations by describing them as baseless and fabricated. In addition, it was only in February 2008 that the U.S. gave the IAEA permission to show any of the documents to Iran to enable it to respond (IAEA Gov/2008/4 at paragraph 37). The U.S. further manipulated the IAEA's efforts by providing "much of this information [to the IAEA] only in electronic form" and "not authorizing the [IAEA] to provide copies to Iran" (IAEA Gov/2008/15 at paragraph 16). The U.S. even refused to give the IAEA itself copies of some material. For example, the U.S. did not let the IAEA have copies of key documents concerning the "ballistic missile warhead" for a "nuclear weapon" Zimmerman refers to. The agency was "therefore unfortunately unable to make them available to Iran."


\/\/. The allegations are not "baseless and fabricated." They are well documented by IAEA. Hell, to believe that the Iranians answered the allegations you have to believe that the Iranians are telling the truth, when their entire response to IAEA has been one of obfuscation and evasion. Of course we only could give the IAEA the docs in electronic form; that's how we got them. That's, in any event, how I would want them.

The reason we did not furnish the documents in detail to the IAEA and Iran is quite simple: they contain weapons details, and the IAEA (let alone Iran) is not allowed to receive that information.
>


> Iran's declination to respond to allegations based on documents it has never been shown, or has only been allowed to peek at, may qualify as a "refusal" to answer. But Zimmerman's failure to mention this circumstance that at least partly explains a "refusal to answer" is incredibly misleading.
>
> Moreover, the IAEA report discloses that Iran has in fact specifically "answered" questions that Zimmerman claims it has "refused to answer," such as "Why is Iran developing the kinds of detonators needed in an atomic weapon?" The "detonators" (exploding bridgewire detonators) were for civilian and conventional military activities, according to Iran (IAEA Gov/2008/15 at paragraph 20). More generally, Iran has told the IAEA that documentation it was permitted to look at was not authentic and had been fabricated. Nevertheless, it "did not dispute that some of the information contained in the documents was factually accurate, but said that the events and activities concerned involved civil or conventional military applicants" (IAEA Gov/2008/15 at paragraph paragraph 18). The report also noted that Iran continued to respond to questions posed by the IAEA.


\/\/Suspicious little me. Exploding bridge wire detectors have some civilian applications, but not many.
>
> Zimmerman's piece is seriously misleading in other important respects. He claims that Iran "has 320 tons of uranium hexafluoride [UF6] gas to feed its centrifuges, enough for almost 100 bombs, but not for even a fraction of one reactor refueling operation." What he does not mention is that "all of [the UF6] remains under [IAEA] containment and surveillance" (IAEA Gov/2008/15 at paragraph 9). He also fails to inform readers that:


\/\/Yes. The UF6 in Iran is under safeguards. With a 90 day notice (as ElBaradei indicated in his statement quoted at the beginning of my article), Iran can abrogate the Nonproliferation Treaty, toss out the inspectors, and break the seals on the UF6 and use it for whatever it wants.

>
> * Without enrichment, 320 "tons" of UF6 is no more dangerous than 320 tons of silly putty.
>

\/\/True indeed. Iran is building enrichment plants which are capable of enriching the UF6 either to fuel grade or weapons grade. But, umm, don't give your kids UF6 instead of silly putty. It's awfully corrosive and toxic.
>
> *
>
>
> * Since it began to enrich uranium, in February 2007, Iran has fed 3,970 kilograms, or less than four metric tons, into enrichment cascades (IAEA Gov/2008/15 at paragraph 2).
> * To get fissile material, uranium must be enriched to consist of 90 percent U-235. Iran's enrichment levels, however, have never exceeded 4.7 percent U-235, a level that could only be consistent with producing nuclear electricity (IAEA Gov/2008/15 at paragraph 5). Iran is scarcely "well on is way" to "mastery" of U-235 production, despite Zimmerman's claim.
>

\/\/I think Mr. Casey is being deliberately obtuse here, and certainly misleading. The amount of material fed to the cascades to date is no measure of what could be fed later. Uranium-235 is fissile at any enrichment; that's a function of the nuclear structure, not the amount, but only a physicist would care. Mr. Casey picks a figure of 90% at which uranium is "fissile;" I think he means an enrichment at which the material is useful in nuclear explosives. He is wrong.

In theory, but not in practice, one can get an explosive chain reaction from 7% material. At 20% Eugene Wigner told me decades ago *he* could build a bomb but, "Peter, you couldn't." I concur completely, and the bomb would be enormous. But 90% is not the threshold for a useful nuclear weapon. The threshold is much lower, but I am not allowed even to hint. But you may well find information in the open literature that points at the actual enrichment in the Hiroshima bomb.

Casey also doesn't understand the physical process of enrichment -- that's clear. The amount of work that goes into enriching uranium is measured in an exotic quantity called Separative Work Units, or SWU (pronounced "swoo."). It should be clear that if you start with natural uranium containing 0.7% U-235, and if you separate that out, tossing away the useless U-238, to reach 4.75% concentration you have done a lot of "separative work". Indeed, by the time you reach 4% you have done MORE than half of the separative work needed to reach 90% U-235. So it is perfectly factual that Iran is well on its way to mastery of the production of weapons quality HEU. And, of course, a stockpile of 4.7% uranium can be reinserted into a centrifuge cascade and quite quickly further enriched to, say, 90%.

> * As have all of its prior reports, the IAEA's May report states: "All nuclear material [at the two Iranian enrichment facilities] remains under Agency containment and surveillance" (IAEA Gov/2008/15 at paragraph 4).

\/\/As I warn, 90 days after Iran files a notice of abrogation, the inspectors are gone. ElBaradei says the same thing.
>
> Zimmerman also contends that Iran's current plans for enrichment are "too small … to provide fuel for a nuclear power program of any consequence," but big enough to enable it to build "twice as many nuclear weapons a year … than they otherwise could have done," providing further evidence that "it is apparent that the real purpose of Iranian enrichment is to provide fuel for weapons, not reactors." This is specious reasoning. Iran's program is R&D.


\/\/Ah yes, the old R&D excuse. Folks you have to ask why a country rich in oil, very rich, and which has been offered all the 4.7% uranium it needs for all the reactors it might ever build at market prices or below wants to invest billions in mastering an exotic technology that will produce reactor fuel at considerably higher prices than market rates.
>
> Laying out plans to construct the Taj Mahal before you know whether you can build a hot-dog stand wouldn't make much sense. Despite its simplicity, moreover, Zimmerman's observation somehow has escaped the IAEA's attention. As recently as May 20 of this year, Mohammed ElBaradei, the head of the IAEA, stated, "We haven't seen indications or any concrete evidence that Iran is building a nuclear weapon and I've been saying that consistently for the last five years."


\/\/Let us repeat; ElBaradei's organization is not empowered to look for weapons-related activities. It is only allowed to ask Iran to prove that all of its uranium remains under seal and hasn't been hidden away. At the moment that is true; there have been no diversions of uranium. The only time IAEA was allowed, told, to look for weapons-related activities was when the Iraqi program was taken down in 1991-98. Since Iran has disavowed its "additional safeguards protocol," the IAEA can't even make snap inspections.
>

> Apparently, ElBaradei does not share Zimmerman's Cheney-esque logic that the possibility that Iran may intend to develop nuclear weapons is evidence that it intends to develop them. And can there be any doubt that, had Iran's current plans been big enough (or when they become big enough) in Zimmerman's opinion to embrace a nuclear power program "of consequence," he would be one of the first to claim that those plans evidence Iran's intent to create even greater multiples of weapon-production capacity?


\/\/Would I? Casey is wrong. I maintain, correctly, that for more than a decade before 2002 Iran surreptitiously engaged in a uranium enrichment progrm in violation of its safeguards obligations. If that program had been exclusively peaceful and commercial, why didn't the Islamic Republic declare it at the inception? If the plans for Natanz had been for about 100,000 or 150,000 P1-class centrifuges, I would have believed that, against economic rationale, Iran was planning to enrich its own uranium for Bushehr because the demand would have matched the output, more or less. It was the small size of the plant that gave away the game. Why? Because Iran would have no need to produce the hundreds of bombs a year that 150,000 machines would allow. But it could keep its reactors going. Oh, just by the way, Iran has no need to enrich uranium for Bushehr: its contract with Russia includes guaranteed fuel services and the removal of spent fuel.

>
> On Aug. 14, 2003, the Washington Post published an opinion piece in which Zimmerman judiciously observed that "[a]vailable evidence demonstrates that Saddam Hussein … lacked a serious nuclear weapons program in 2003. And if Mr. Bush had not held out the threat of Iraqi nuclear weapons 'within months,' it is doubtful that Congress would have given him a blank check. How can one conjure up a benign explanation for the president's assertions?" The essay concluded that "[t]he next time Bush wants to use armed force to preempt or prevent an attack on this country, he will have to prove his case far more completely than before. [The president] of the United States [has] forfeited the benefit of the doubt."
>
> Zimmerman's recent Globe commentary concludes that "If Iran begins enriching uranium to weapons grade on an assembly-line basis, it could transfer this material to groups such as Hezbollah and Hamas, which might fabricate low-technology nuclear explosives. These would probably have yields nearly as high as the bomb that destroyed Hiroshima."
>
> If. Could. Might. Nuclear weapons. Assembly line. Hezbollah. Hamas. Hiroshima. Is it possible that this agitprop could have been written by the same man who wrote in August 2003 that "The president's principal argument for going to war – to prevent a 'smoking gun that would appear as a mushroom cloud' – was based on bad intelligence that was misused while good intelligence was ignored"?


\/\/Why yes indeed, the 2 were written by the same man. Casey is unable to understand that the data input to my brain are different now than in 2003. In 2003 I knew that the Iraqis had absolutely no capability to enrich or reprocess uranium and tht the weapons scientists had been scattered to other projects. In 2008 I know that the Iranians are building a weapons-program sized enrichment plant and have concentrated their scientists. They've also taken the first experimental steps towards design of a good weapon -- something that Iraq never did!
