Former Mossad agent Avner Phelan says that the IAEA report on the Usafia site raises concerns about enriched materials.
Phelan said that if a uranium enrichment site existed there and fissile materials were found, perhaps part of the 60% enriched stockpile, the assumption that Iran would not be able to reach them in the last year and a half is more dangerous. According to him, the large site, with many buildings and entrances, could allow activity that hides access to materials and centrifuges, and he expressed doubt about monitoring any such activity from the air. He described the development as not a game changer, but a reminder of the limits of two rounds of war and talks.
