Unfettered access to sites, facilities, material, equipment, people, and documents is imperative to the credible long-term verification of any nuclear agreement with Iran. This “anywhere, anytime” access and short notice inspections must not be subject to a dispute resolution mechanism, which would delay the International Atomic Energy Agency’s (IAEA) access. Procedures in a final deal, which provide Iran with the ability to define or control access, undermine the verifiability of the agreement and affect the IAEA’s ability to reach timely conclusions. Additionally, the resolution of the IAEA’s outstanding concerns regarding the possible military dimensions of Iran’s program must be resolved prior to the provision of substantial sanctions relief.
