    Unresolved U.S.-Iran hostilities, Gulf insecurity, and nuclear verification gap

    The June peace announcement and MOU remain official diplomatic records, but renewed July U.S.-Iran combat and continuing attacks affecting Gulf states and shipping show that durable implementation is not verified. The February-April U.S.-Israeli campaign entered suspension; no approved baseline source establishes Israeli participation in the July U.S. rounds. The IAEA still cannot verify most current nuclear inventory or activity beyond limited Bushehr access. No final comprehensive peace treaty or continuously observed permanent ceasefire is verified.

    IAEA can verify Bushehr but not most of Iran nuclear inventory or activity

    The IAEA observed additional damage at Natanz and severe damage at the Khondab Heavy Water Production Plant after reported attacks, while the UN documented humanitarian effects in Iran. Except for limited Bushehr access, the Agency lacked required information and access to verify most declared facilities, the uranium stockpile, enrichment activity, centrifuge inventories, reprocessing, or heavy-water activity. Do not present the program as destroyed, intact, dormant, or weaponized as a verified current fact.

    IAEA access collapses, UN measures return, and a safeguards arrangement fails

    IAEA verification stopped during the attacks and inspectors withdrew for safety. Iran enacted a law suspending cooperation, while the Agency maintained that the comprehensive safeguards agreement could not be suspended by domestic law. A later Cairo arrangement did not restore full verification; prior UN measures were reapplied through the Resolution 2231 process, and Iran later regarded the Cairo arrangement as terminated.

A drone struck Tower 22 in Jordan on 28 January 2024, killing three U.S. service members; the United States then struck facilities in Iraq and Syria.
