No loophole

Seyed Hossein Mousavian, who has worked at Princeton since 2009, is the moderate voice of the Iranian regime, which lacks an ambassador (other than at the UN), in the United States. He said yesterday, in an interview with Die Welt (Moussavian provided the English translation):

R&D on nuclear weapons is not prohibited by NPT. NPT prohibits building, storage and the use of nuclear weapons. For many years Germany is doing R&D on nuclear weapons under IAEA’s supervision. Because Berlin wants to know the consequences of possible use of nuclear bomb against Germany by other nuclear powers. It is legitimate as long as the nuclear powers maintain thousands of nuclear weapon.

To me, this is one of the most interesting remarks in a lengthy presentation that helpfully and clearly outlines main parameters of a possible nuclear agreement with Iran:  limiting Iran’s enrichment and reprocessing capabilities to meeting its practical requirements (and thereby making the time it would take to achieve a nuclear weapons capability at least a year) in exchange for lifting of sanctions, starting with European oil and financial sanctions.

Whereas those parameters may be mostly agreed, as Moussavian suggests, the parties seem far apart on the question of nuclear weapons research and development, if Moussavian’s remarks represent accurately what people in Tehran are thinking.* Germany certainly does conduct research on the impact of ionizing radiation, a subject on which its scholars have been leaders since the discovery of X-rays in 1896 (I should know: I wrote my doctoral thesis at Princeton on the early history of protection against ionizing radiation). That is quite different from conducting research on how to initiate a nuclear detonation, which is what the Americans think Iran was up to at Parchin before 2003.

While a great deal more attention has been paid to the number of centrifuges and the quantity of enriched uranium Iran will retain under a possible nuclear agreement, the issue of clandestine nuclear weapons research is really far more important. I don’t know of a single case of nuclear proliferation due to materials and facilities monitored by the International Atomic Energy Agency (IAEA). Moussavian is correct in believing that an agreement that limits enrichment and reprocessing and enables the agency to keep tabs on all of Iran’s declared facilities should be adequate to provide at least a year of warning if there is any attempt at diverting material to a nuclear weapons program.

But that is not sufficient, especially if Iran is now claiming a right to conduct nuclear weapons research. I know of no such right in the Non-Proliferation Treaty (NPT). Nor to my knowledge has the IAEA ever agreed to monitor the nuclear (e.g. initiators) or non-nuclear (e.g. high explosive) research needed to develop nuclear weapons. Such research would be inconsistent with the purposes of the treaty. The IAEA’s interest in Parchin is not in order to monitor the activity but to understand Iran’s intentions. I won’t claim non-nuclear states have never done experiments of the sort Iran is accused of conducting at Parchin, but Iran is not just any non-nuclear state. It can expect no US relief from sanctions if it insists that conducting nuclear weapons research is legitimate. I doubt even the Europeans will fall for that one.

That comes from someone who would very much like to see an agreement within the parameters Moussavian suggests reached by the June deadline. But ending nuclear weapons research in Iran permanently and verifiably has to be part of the deal. Anything less leaves a giant loophole.

*PS:  on this point, Moussavian writes: “Iran neither had research on nuclear weapons nor has such agenda. As a scholar, I stated my personal interpretation from NPT which I believe it is correct. It has nothing to do with Iran’s position.”
