440kg of Enriched Uranium: Central Sticking Point in Iran Conflict
Israeli Prime Minister Benjamin Netanyahu asserts that the conflict with Iran can only end once all highly enriched uranium is removed from the country. Approximately 440 kilograms of uranium enriched to 60 percent remain a critical contention point, with experts estimating sufficient material for several atomic bombs. IAEA Chief Rafael Grossi indicates the material is likely stored in underground facilities at Isfahan and Natanz, though independent oversight has ceased following US and Israeli attacks in June 2025. While US President Donald Trump aims to physically recover the uranium, Tehran rejects transferring it to the US, offering instead to dilute the material under supervision if its right to an independent nuclear program is recognized. Military recovery is deemed extremely difficult and risky by experts. Furthermore, securing the current stockpile does not resolve the underlying issue, as Iran retains technical know-how and additional uranium stocks to potentially rebuild enrichment capabilities. The removal of these stocks remains a red line for the US administration, complicating diplomatic resolutions.
