Iran, US Enter Critical Implementation Phase of Historic Peace Accord
GENEVA — The United States and Iran entered a critical implementation phase of their historic peace accord Thursday, with International Atomic Energy Agency inspectors beginning the verified destruction of Iran’s enriched uranium stockpile at the Natanz facility under a monitoring regime that both sides have described as unprecedented in scope.
The developments marked the first concrete steps following the June 19 signing ceremony in Geneva, where U.S. and Iranian officials shook hands on a memorandum of understanding that ended weeks of hostilities in the Persian Gulf and the Strait of Hormuz. The agreement halted a blockade that had caused oil prices to spike to $140 per barrel and prompted emergency consultations at the United Nations Security Council.
IAEA Director General Rafael Grossi confirmed the inspection regime was fully operational. “The access granted by Tehran represents the most rigorous verification framework ever agreed to by any country in the history of the agency,” Grossi said in a statement from Vienna. The agency deployed 47 additional inspectors to Iranian nuclear sites, with real-time monitoring feeds routed to its headquarters and shared with Washington through a joint monitoring channel established in Doha.
Uranium Destruction Begins at Natanz
Technicians at the Natanz enrichment complex began the controlled dissolution of approximately 3,200 kilograms of low-enriched uranium hexafluoride under IAEA supervision Thursday morning, according to a statement from Iran’s Atomic Energy Organization. The material, sufficient for a potential weapons program if further enriched, is being converted into a stable oxide form unsuitable for military use.
The process is expected to take 90 to 120 days to complete, with IAEA inspectors conducting daily inventories and submitting weekly reports to the U.N. Security Council. The United States has agreed to lift sanctions progressively as verified benchmarks are met, with a full sanctions release tied to a final IAEA declaration of complete nuclear transparency.
European Union foreign policy chief Kaja Kallas, who brokered the Geneva negotiations alongside Qatar, welcomed the initial steps. “Today we see implementation beginning in good faith. This is what months of quiet diplomacy were designed to produce,” Kallas told reporters in Brussels.
Sanctions Relief and Economic Reopening
The U.S. Treasury Department issued general licenses Thursday authorizing food and medicine exports to Iran for the first time in seven years, while maintaining restrictions on oil sales and financial sector contacts pending further progress. The Office of Foreign Assets Control clarified that Iranian banks previously blacklisted would remain sanctioned unless individually delisted through a new interagency review process.
Iran’s rial strengthened by 12 percent against the dollar Thursday as markets priced in the prospect of sanctions relief. Iranian state media broadcast images of oil tankers preparing to transit the Strait of Hormuz for the first time since the blockade began, though commercial shipping insurers said it would take weeks before normal traffic patterns resumed.
Secretary of State Marco Rubio, speaking in Washington, struck a cautious note. “The United States will not hesitate to reimpose sanctions in 24 hours if Iran violates any terms of this agreement,” Rubio told reporters. “This is not trust. This is verify. The monitoring channel in Doha exists precisely so there are no misunderstandings about what is taking place at these facilities.”
Regional Reactions and Remaining Friction Points
Israel expressed sharp reservations about the pace of sanctions relief, with Prime Minister Benjamin Netanyahu’s office issuing a statement calling for maximum pressure until every nuclear centrifuge is dismantled. Saudi Arabia and the UAE congratulated both governments but quietly pressed Washington to maintain arms sale commitments and existing security guarantees in the Gulf.
Congressional reaction was divided along party lines, with Senate Foreign Relations Committee members from both parties demanding classified briefings before endorsing any permanent sanctions relief. Representative Michael McCaul, the committee’s Republican chair, said he was cautiously optimistic while emphasizing the need for rigorous IAEA reporting.
The Iran Nuclear Agreement, as both governments have begun calling the accord, faces its next major test in August when the IAEA must certify the destruction of the first 500 kilograms of enriched material. A joint commission including American, Iranian, European, and Chinese representatives is scheduled to meet in Vienna on July 15 to review implementation progress.
Diplomats familiar with the process said the August deadline was the most politically sensitive checkpoint in the agreement. “The next six weeks will determine whether this holds. Both sides have domestic constituencies who want this to fail, and we must not underestimate that pressure,” one senior European official said, speaking on condition of anonymity to discuss ongoing negotiations. Observers in Vienna said the outcome of the July 15 commission meeting would provide the clearest signal yet of whether the accord can survive its first major stress test.
