We all hear what he says and take it with a pinch of salt. There is normally a mixture of truth, exaggerations and lies in what he says. The Institute for Science & International Security posted a report in November 2025 with extensive information and satellite images (too long to post in full here but link is provided).
Comprehensive Updated Assessment of Iranian Nuclear Sites Five Months After the 12-Day War (November 2025)
The Institute previously published a comprehensive assessment of major sites attacked in late June, just after the war’s end and subsequently published additional studies on damage to individual sites. Overall, the damage caused by airstrikes to numerous nuclear sites was extensive and, in many cases, catastrophic.
Iran has since undertaken damage assessments and efforts to conduct clean up and fortification work to varying extent at several sites.
The main nuclear sites at Fordow, Natanz, and Esfahan were largely destroyed and have seen little significant activity since the war. The extent of damage to the tunnel portion of the Esfahan mountain complex remains unknown but could be severe. The activities at Fordow to the extent visible appear to have been mainly related to damage assessments and minimal clean up. At Natanz, activities also point towards protecting the site’s remaining utilities against future attacks.
A major exception is at the Esfahan mountain complex, where Iran has taken actions to allow access and better protect at least one of the three tunnel entrances leading into the mountain. This tunnel entrance may have been recently accessed. In a recent image, dated November 20, one portal entrance appears open. In addition, the image shows that Iran may have installed what can effectively be called "Cruise Missile Chicane Barriers." Two thick protective barriers work together to block a missile flying straight at the entrance.
Overall, satellite imagery indicates that Iran's uranium enrichment program remains significantly set back. At present, Iran does not appear able to enrich uranium in any significant manner or make gas centrifuges in significant numbers. Iran’s key nuclear enrichment facilities, its facility to produce uranium hexafluoride (UF6) and its centrifuge manufacturing and research and development facilities remain severely damaged or destroyed.
Unlike the enrichment-related sites attacked, select nuclear weaponization sites show extensive clean-up efforts. Based on satellite imagery, at least three weaponization-related sites that were attacked have undergone cleanup activities that appear to include salvaging of remaining equipment and thus may be the prelude to rebuilding or related to sanitization activities.
In addition, a nuclear weaponization site called Taleghan 2, not attacked in June but destroyed in the fall of 2024, has undergone significant construction activity over the last year. It now appears near completion, and holds a large, cylindrical chamber, which could be a high-explosive containment vessel suitable for nuclear weapons development activities.
There are ongoing construction efforts at a mountainous area just south of the Natanz enrichment site known by its tallest peak as “Pickaxe Mountain.” This site was not visibly attacked in June and comprises two underground tunnel complexes, one still under construction, labeled the Pickaxe Mountain Tunnel complex, and another built in 2007 and called the 2007 tunnel complex. Iran announced in 2020 that the purpose of the Pickaxe tunnel complex is to hold an advanced centrifuge assembly facility that can produce several thousand centrifuges a year. In addition, based on the estimated size of the underground halls, the Institute several years ago assessed that site could also hold a centrifuge enrichment facility.
