Probability Of US Or Israeli Ground Operation To Physically Retrieve Iran's 440 Kilogram 60 Percent Enriched Uranium Stockpile Rises As MOU Collapses
Source: TWZ
EXECUTIVE SUMMARY
The War Zone on May 11 published an analysis assessing that the probability of a US or Israeli ground operation to retrieve Iran's 440.9 kilogram stockpile of 60 percent enriched uranium has risen materially since Tehran's May 10 MOU rejection. The stockpile is sufficient, if further enriched to weapons grade, for approximately 10 nuclear weapons per current IAEA director general Rafael Grossi statements. Almost half of the stockpile is assessed to remain at Iran's Isfahan facility in an underground tunnel complex. IAEA verification access has been terminated since the February 28 opening day strikes; surveillance cameras have been disabled and seals removed at all declared facilities.
ANALYSIS
The retrieval option is one of three publicly discussed US policy paths. Path one is a follow on strike package targeting Iranian nuclear infrastructure directly, including Natanz, Fordow, and Isfahan, replicating and expanding on Operation Midnight Hammer and Operation Epic Fury. Path two is a US or Israeli special operations ground raid to seize or destroy the HEU stockpile in place. Path three is sustained kinetic and economic pressure aimed at coercing Iran back to the MOU framework with marginal concessions.
The ground raid path has been contemplated in US policy discussion since at least April per a Foreign Policy assessment. Operational complexity is substantial: the Isfahan tunnel complex is hardened, defended, and almost certainly surveilled by Iranian IRGC and MOIS. Recovery of physical material in transit poses additional contamination and counter strike risk. Israeli special operations forces have the training and equipment for this mission set; US Joint Special Operations Command has the air and logistical reach.
Iranian Foreign Minister Abbas Araghchi has publicly questioned the IAEA's claim on the 440 kg figure, characterizing the stockpile location as uncertain. US intelligence has assessed Iran's nuclear weapon timeline as unchanged despite months of war, per Turkiye Today citing US officials. The combination of unclear stockpile location and unchanged breakout timeline elevates the policy incentive for a physical retrieval that would resolve both verification and capability questions in a single action.
Risks of an unsuccessful retrieval are severe. A failed raid would compromise the political case for further US action, generate Iranian retaliation likely against US homeland critical infrastructure or US persons abroad, and could contaminate retrieval personnel and platforms. A successful raid would resolve the 440 kg issue but would not address Iranian centrifuge production capacity, which would resume enrichment within months unless centrifuge facilities are also destroyed.
