Iran Built a Facility to Develop Nuclear Weapons and Hid It from Inspectors during Negotiations with the West

April 13 2020

In 2018, the Mossad succeeded in capturing the Islamic Republic’s secret nuclear archive, which experts are still in the process of analyzing and comparing with other sources. One recent discovery is the previously unknown Shahid Mahallati “uranium-metals workshop.” Built in 2002 and operational by 2003, this facility was intended for use as a temporary “pilot plant” to function alongside the main site at Parchin. The latter site, Parchin, was intended to produce enough weapons-grade uranium to build a few nuclear weapons every year. David Albright, Sarah Burkhard, and Frank Pabian describe the purpose of the pilot plant:

Building . . . a production-scale uranium-metallurgy plant is complicated. This plant needs to be capable of making uranium metal, melting it, casting it into molds of necessary shapes, and finishing quality-controlled weapon components. . . . Overcoming these difficulties would typically call for a pilot plant, designed to develop and test critical procedures, . . . starting with surrogate materials [with properties similar to uranium’s], then introducing natural uranium, and later processing weapon-grade uranium.

Since [planners] viewed the pilot plant as temporary, its equipment and personnel would likely be transferred to [Parchin] once the main plant was nearing completion. If [the main plant] failed to become operational by the time the first batch of nuclear explosive material was available, the pilot plant could have served another temporary purpose as well, producing the first weapons-grade uranium core of a nuclear weapon.

Thus Iranian scientists could use Shahid Mahallati to practice the techniques necessary for making the components of a nuclear bomb, without wasting precious uranium. Lest there be any doubt about Tehran’s intentions in building the facility, the documents in the archive describe the creation of a cover story about the plant’s use in order to avoid raising the suspicions of foreign intelligence agencies or overseas suppliers of raw materials.

The pilot plant was shut down by 2011, although its personnel, the research done there, and even some of the equipment and materials were likely transferred to other secret research sites. But even if this were not so, the very fact of Shahid Mahallati’s existence shows that Tehran failed to comply with the 2015 nuclear deal from day one:

As in many other cases, Iran has clearly been dishonest with the International Atomic Energy Agency (IAEA). During discussions in September 2015, [conducted pursuant to the deal’s terms], “Iran informed the agency that it had not conducted metallurgical work specifically designed for nuclear devices, and was not willing to discuss any similar activities that did not have such an application.” The activities at Shahid Mahallati and [Parchin] are a dramatic contrast to that statement, activities highlighting once again that Iran furthered its nuclear-weapons capabilities far more than was known prior to Israel’s seizure of the nuclear archive, permitting Iran today to build nuclear weapons faster than previously believed.

The Next Diplomatic Steps for Israel, the Palestinians, and the Arab States

July 11 2025

Considering the current state of Israel-Arab relations, Ghaith al-Omari writes

First and foremost, no ceasefire will be possible without the release of Israeli hostages and commitments to disarm Hamas and remove it from power. The final say on these matters rests with Hamas commanders on the ground in Gaza, who have been largely impervious to foreign pressure so far. At minimum, however, the United States should insist that Qatari and Egyptian mediators push Hamas’s external leadership to accept these conditions publicly, which could increase pressure on the group’s Gaza leadership.

Washington should also demand a clear, public position from key Arab states regarding disarmament. The Palestinian Authority President Mahmoud Abbas endorsed this position in a June letter to Saudi Arabia and France, giving Arab states Palestinian cover for endorsing it themselves.

Some Arab states have already indicated a willingness to play a significant role, but they will have little incentive to commit resources and personnel to Gaza unless Israel (1) provides guarantees that it will not occupy the Strip indefinitely, and (2) removes its veto on a PA role in Gaza’s future, even if only symbolic at first. Arab officials are also seeking assurances that any role they play in Gaza will be in the context of a wider effort to reach a two-state solution.

On the other hand, Washington must remain mindful that current conditions between Israel and the Palestinians are not remotely conducive to . . . implementing a two-state solution.
