Current nuclear deal will put in place sufficient measures to block Iran's path to a nuclear weapon
MYTH: A comprehensive deal will not prevent Iran from developing nuclear weapons using a covert program.
REALITY: A comprehensive agreement will block Iran's uranium and plutonium pathways to the bomb. Among other features, the agreement will set verifiable limits on Iran's uranium-enrichment capacity and its stockpiles of enriched uranium. It would also dramatically cut the output of weapons-usable plutonium at the Arak heavy-water reactor. U.S. negotiators have stated that an acceptable final deal will push the time it would take Iran to produce enough highly enriched uranium for one bomb to 12 months.
A comprehensive deal also would put in place additional measures to ensure that any covert program is deterred or quickly detected. The additional monitoring and verification under the interim agreement has already dramatically expanded international oversight of Iran's nuclear program through increased IAEA access to sites. A comprehensive deal will provide additional monitoring and verification.
In addition, Iran has agreed to implement and ratify the additional protocol as part of a comprehensive deal. Specifically, it gives the IAEA expanded right of access to information and sites. With the additional protocol, the agency will have regular access to Iran's entire fuel cycle, including facilities such as Iran's uranium mines, centrifuge production facilities, and heavy-water production plant. This will make it far more difficult for Iran to siphon off materials for a covert program.
The additional protocol also helps the IAEA check for any clandestine nuclear activities in Iran by providing the agency with greater authority to carry out inspections in any facility with nuclear material. It also enables the agency to visit the nuclear facilities on short notice, making it more difficult to cover-up any activities intended to divert materials or that are inconsistent with a facilities' stated purposes.
The agreement is based on verification, not trust. According to the U.S. fact sheet, Iran has agreed to accept the IAEA’s Additional Protocol as well as several even more intrusive monitoring and inspection measures that will provide high confidence that Iran is not making bomb material at its declared nuclear facilities and will significantly strengthen the ability of inspectors to detect clandestine facilities
