Enriched uranium and poverty of scruples - The Island
Share Tweet Tuesday 12th May, 2026 US President Donald Trump yesterday rejected Iran’s response to his peace proposal. He wants the conflict ended on his own terms, but Iran is not amenable to that idea. Oil prices have gone up again. The economic cost of the US-Israeli war on Iran is incalculable, as is obvious. There has been a welcome pause in the conflict, thanks to a fragile ceasefire, but economies across the world are still reeling due to a global energy crisis. CEO of Saudi Aramco Amin Nasser is of the view that the world has lost about one billion barrels of oil over the past two months, and it will take energy markets a considerable time to stabilise even if the oil supplies resume via the Hormuz Strait, the closure of which has curtailed shipping and sent energy prices through the roof. It is not only energy supplies that have suffered due to the US-Israel military campaign; many countries are experiencing crippling fertiliser shortages as well, so much so that the Food and Agriculture Organization of the UN has warned of a possible decline in global agricultural output. Most of all, the human cost of the war has been enormous for Iran. Israeli Prime Minister Benjamin Netanyahu, who considers the war on Iran a dream come true for him, and is trying to turn his country’s military might into political gain, has reportedly said that there is still “work to be done” in Iran. He says Iran has retained many of the capabilities it had at the start of the war. Iran has not given up its enriched uranium or dismantled its nuclear sites, he has said. This claim is at variance with President Trump’s statement that the US military has “beaten and completely decimated” Iran. Netanyahu himself has also bragged that Iran has been militarily weakened as never before. Netanyahu wants enriched uranium in Iran removed urgently. He says that can be done as part of an agreement to be reached. He has stopped short of mentioning any timeline for the proposed task. Trump has expressed a similar view. An Iranian news outlet linked to the country’s armed forces has denied reports that Tehran agreed to allow its enriched uranium stocks to be removed as part of talks with the United States. Thus, the uranium issue is sure to stand in the way of finding a lasting solution to the West Asia conflict, saving lives and properties and facilitating uninterrupted energy and fertiliser supplies via the Hormuz chokepint. The US-Israeli military campaign has apparently strengthened...
Iran Nuclear Status — Enrichment & Breakout Timeline
Iran's nuclear program has been significantly impacted by Operation Epic Fury strikes but not eliminated. As of May 11, 2026, Iran holds 440.9kg of 60%-enriched uranium (per IAEA DG Grossi), enough for approximately 10 weapons if further enriched to 90% weapon-grade. Iran was not actively enriching as of February 25 per Secretary Rubio and IAEA. Post-strike breakout is estimated at 12 weeks under the most likely scenario. 440.9kgHEU at 60% 60%Current enrichment 12 wkPost-strike breakout DeniedIAEA access status Nuclear Facility Damage Assessment FacilityTypeDepthDamagePost-Strike Status Natanz FEP Enrichment (main) 8m underground 75% Severely damaged Natanz R&D Advanced centrifuge R&D Surface 95% Destroyed Fordow (FFEP) Enrichment (hardened) 80m underground 30% Partially damaged Isfahan UCF Uranium conversion Surface 90% Destroyed Arak IR-40 Heavy water reactor Surface 60% Heavily damaged Parchin Weaponization R&D Tunnels 50% Damaged Saghand Mine Uranium mining N/A Not struck Intact Suspected covert site Unknown Unknown Not struck Unknown Breakout Timeline Estimates ScenarioTimeConfidenceDetail Pre-strike baseline 2 weeks HIGH Before Feb 27 strikes — Iran was ~2 weeks from enough HEU for one device at 60% starting purity Post-strike (current) 12 weeks MEDIUM Natanz/Isfahan damage sets back centrifuge cascade.

Surveillance cameras have been disabled and seals removed from all declared facilities. The IAEA is unable to verify the extent of strike damage, the status of enriched material stockpiles, or whether covert enrichment activities continue. This is the most significant IAEA verification blackout since the agency began monitoring Iran's nuclear program. Key Nuclear Assessments Natanz FEP: Main enrichment plant severely damaged (75%). 6,000+ IR-1 centrifuges destroyed. Above-ground halls collapsed. Fordow FFEP: Deep mountain bunker only 30% damaged. GBU-57 MOPs caused tunnel collapses but core facility may be intact. This is the greatest proliferation risk. Stockpile status: ~2,600kg of enriched uranium destroyed in strikes....

AP But major sticking points remain — especially over Iran's stockpile of enriched uranium and whether or when Tehran would be allowed to resume any enrichment activity in the future. "The main hurdle is the duration of enrichment restrictions," a Pakistani source told The Post on Wednesday. "There's no final deal yet."

Executive summary Iran's February 26, 2026, Geneva proposals included offers to downblend or limit certain stocks of highly enriched uranium and to accept increased IAEA oversight, a package that Omani mediators and at least one UK security adviser described as significant progress and potentially credible [1] [2].
