I reviewed Shahram Chubin’s Iran’s Nuclear Intentions for the journal Middle East Policy.

In that review, I discussed the provenance of the 2005 NIE on Iran’s WMD programs. Chubin asserts that members of the US intelligence community produced a “tainted” National Intelligence Estimate on Iran’s nuclear program that underestimated how close Iran was to building a nuclear weapon, in order to support a late 2005 effort to engage Iran.

For those advocating regime change, it was important to demonstrate that there remained time for [a graduated, deliberate approach] (and a sanctions policy) to be viable, which may have accounted for the “new intelligence estimate” in August 2005 that assessed Iran to be technologically further away from a nuclear weapon than many had assumed.44

44. This estimate, however, might well be tainted. Before this National Intelligence Estimate (NIE), U.S. estimates, such as that by Defense Intelligence Agency Director Lowell Jacoby in February 2005, were “within five years.”

This is wrong and it matters. How close Iran is to a bomb is the most important “fact” bearing on the prospects for a diplomatic solution to the current impasse over Iran’s nuclear ambitions. If Iran is five-to-ten years away, then we have time for patient, tough diplomacy.

The National Intelligence Estimate (or NIE) in question was commissioned in January 2005 by then acting-chair of the National Intelligence Council David Gordon.1 The previous NIE on Iran had been produced in 2001.2 Paul Pillar, then-National Intelligence Officer for the Near East and South Asia, was responsible for overseeing the drafting and coordination of the estimate. The process for commissioning NIEs – an authoritative, community-wide estimate related to a particular issue – is well described in the public policy literature.

The NIE dealt with political, economic and social trends in Iran, emphasizing issues relating to the stability of the regime in Tehran. Along with the NIE, Gordon also commissioned a “memo to holders” to update a preceding national intelligence estimate about Tehran’s chemical, biological and nuclear capabilities. Robert Walpole, National Intelligence Officer for Strategic and Nuclear Programs, presumably oversaw the “memo to holders.” Both documents – the NIE on political stability and the “memo to holders” on Iran’s WMD programs (which was appended to the NIE) – were completed in May 2005.

There is no evidence to support the idea that senior US policy makers favoring diplomacy, rather than Gordon as acting Chairman of the NIC, commissioned the estimate or that Gordon had any other motive. U.S. officials in February 2005 told Maxim Kniazkov of Agence France Presse that the “memo to holders” was “self-initiated” adding “It is not that somebody has requested it.”3

The intelligence community had plausible reasons in January 2005 to turn to its assessments of political stability and nuclear policy in Iran. Following the Iraq Survey Group’s interim report in October 2003 that suggested Iraq did not possess militarily significant stockpiles of weapons of mass destruction, the intelligence community revisited many of its WMD-related assessments.4 As noted, the look at Iran’s nuclear program was not, in fact, an NIE but rather a “memo to holders,” a document that updates an existing national intelligence estimate based on new information, without providing a comprehensive reassessment.5 By January 2005, thanks to the activity of international nuclear inspectors to verify Iran’s suspension of enrichment activities under the terms of the November 2004 Paris Agreement, the intelligence community would have had access to enough new information to justify such an update.6 It is likely that Gordon, anticipating briefings on the inspectors’ visits to Iran, decided to update the preceding NIE on Iran’s nuclear program on this basis.

Although both documents—the NIE on political stability and the “memo to holders” on Iran’s WMD programs—were completed in May, the results did not appear in the press until August 2005 (accounting for Chubin’s confusion regarding the publication date). On August 2, Linzer reported that the “memo to holders” had concluded Iran was 5-10 years away from a nuclear weapon, stating that Iran could complete a nuclear device “early to mid next decade.”7 The conclusions of the NIE about the political stability of the Iranian regime appeared in Newsweek two weeks after Linzer’s story.8

Chubin asserts that Iran might be very much closer to nuclear weapon, but he does not address the substance of the NIE. Chubin cites one analyst warning that “What remains is for [Iran] is to assemble, test and run a few thousand centrifuges with the feed stocks produced at the UCF.”9

Public accounts of IAEA findings suggest Iran continues to find such challenges are far from trivial. An IAEA report that argued that Iran continues to have difficulty understanding the relationship between UF6 gas flow, temperature and stress corrosion. A “Western Intelligence official” explained to the Washington Post’s David Ignatius in September 2006 that “The Iranians are unable to control higher temperatures, and after a short period they must stop because of higher temperatures. So far they haven’t been able to solve this.” The official added that some centrifuges “are simply crashing—10 or so have broken down and must be replaced.”10

Indeed, the other estimate that Chubin cites, by David Albright and Corey Hinderstein of the Institute for Science and International Security, states quite clearly that their estimate “reflects a worst-case assessment” adding that “Iran can be expected to take longer”:

Iran is likely to encounter technical difficulties that would delay bringing a centrifuge plant into operation. Factors causing delay include Iran having trouble in the installation of so many centrifuges in such a short time period, or Iran taking longer than expected to overcome difficulties in operating the cascades as a single production unit or commissioning the secret centrifuge plant.11

Albright and Hinderstein do not, as one might have supposed from Chubin’s description, minimize the impact of these technical hurdles. Indeed, in subsequent reports, Albright, writing with Jacqueline Shire, has noted that Iran has made “limited progress at its Natanz uranium enrichment plant, installing and operating fewer gas centrifuges than expected. Senior Vienna-based diplomats have confirmed to ISIS that Iran may be either delaying deliberately the pace of its work while diplomatic efforts are underway, or is experiencing technical problems with its centrifuge program.”12

Such technical troubles, revealed by international nuclear inspections, appear to have influenced the conclusion of the May 2005 memo to holders that Iran remains five to ten years from building a nuclear device.

Recent public statements suggest that a new forthcoming NIE on Iran’s nuclear program will not significantly alter this estimate.13 This is not to say that Iran is not making progress toward mastering enrichment, but merely that time remains for diplomacy.
