Jane Darby Menton of the Carnegie Endowment for International Peace published analysis on or around Thursday arguing that a nuclear moratorium cannot function without verification, and that IAEA access has been effectively curtailed for eight months with no negotiation on inspection architecture 1. The lockout traces to the Majlis's 221-0 vote on 11 April to suspend all cooperation with the agency, which has not been reversed. Iran's actual negotiating position remains a five-year moratorium with HEU (Highly Enriched Uranium) transfer, the position Tehran has held since the Islamabad round broke down .
The Wall Street Journal reported a fifteen-year freeze as the analyst landing zone on the US side 2. Israel Hayom had carried that framing first on 3 May , and major wire services have not corroborated the figure as an Iranian offer. The decade-long gap between Iran's five and the US fifteen is the headline arithmetic of the negotiation. The Carnegie analysis argues that the headline arithmetic is unmeasurable while the inspection regime that would confirm any number remains absent.
A pause at three years or thirty is unverifiable in either direction without IAEA inspectors on the ground; with the IAEA locked out, neither side is currently negotiating the architecture that would convert any agreed duration into a checkable fact. Menton's argument is that both the US MoU and Iran's counter-offer are structurally undeliverable in their current form, because the body that would certify either is not present at any working session.
