Iranian President Offers to Dilute Enriched Uranium and Accept IAEA Verification at UNGA While Blocking Inspectors

BLUFIran is very unlikely to readmit IAEA inspectors within two months, as Pezeshkian's dilution offer lacks any commitment to the verified access needed to confirm it.

Iranian President Masoud Pezeshkian told Fox News' Bret Baier on Thursday that Tehran is willing to dilute its 60%-enriched uranium stockpile and submit to international verification, calling the material "not a big deal" 12. Pezeshkian denied Iran seeks a nuclear weapon, citing a religious edict from the "martyred" supreme leader, and said Iran would relinquish the 60%-enriched uranium "within the framework" of the Non-Proliferation Treaty 12. When Baier pressed him on Iran blocking IAEA inspectors since cutting ties with the agency in 2025, Pezeshkian did not commit to readmitting them, instead citing NPT provisions barring military strikes on IAEA-monitored facilities 1. He blamed Washington for the nearly seven-month war and the collapse of the June ceasefire framework he signed with President Trump, while denying knowledge of reports that Iran used Chinese satellite imagery to strike a U.S. base in Jordan 23. Pezeshkian also disclosed he met face-to-face for several hours with new Supreme Leader Mojtaba Khamenei, who succeeded his "martyred" father Ali Khamenei, about a month before the interview, calling him "completely" healthy and actively directing Iran's leadership, and said Tehran wants to revive the June ceasefire memorandum with Washington before the November U.S. midterm elections 2. The interview followed his UN General Assembly address Wednesday, where he told Trump Iran would "never bend the knee" 1.

Analysis
Iran is very unlikely to formally readmit IAEA inspectors within the next two months to verify any dilution of its 60%-enriched stockpile, since Pezeshkian repeatedly declined to commit to renewed access even while offering rhetorical concessions on dilution and verification to a US audience, instead invoking NPT provisions shielding IAEA-monitored sites from strikes, a formulation that functions as leverage rather than policy. Confidence in this judgment is low, given reliance on unscripted television remarks rather than any documented shift in Tehran's inspection policy, and the claim rests on a single Fox News interview amplified but not independently verified by secondary outlets. This confirms rather than resolves the gap the IAEA flagged in June, when it lost ability to verify the 440kg stockpile's location. Pezeshkian's offer arrives with no corresponding access commitment, and the remarks may function primarily as messaging aimed at US domestic debate over Trump's Iran policy rather than a negotiating shift. Absent verified access, Washington retains no independent baseline to confirm any dilution claim, leaving the administration to weigh military options against an unverifiable stockpile.
