More Than 70 Nuclear Nonproliferation Experts Announce Support for the Joint Comprehensive Plan of Action

 Iran Nuclear Deal "A Net-Plus for International Nuclear Nonproliferation"

For Immediate Release: August 18, 2015

(Washington, D.C.)—More than 70 of the world's leading nuclear nonproliferation specialists issued a joint statement outlining why the Joint Comprehensive Plan of Action (JCPOA) “is a strong, long-term, and verifiable agreement that will be a net-plus for international nuclear nonproliferation efforts.”

The group of experts write in their statement that the July 14 agreement “ … advances the security interests of the P5+1 nations (China, France, Germany, Russia, the United Kingdom, and the United States), the European Union, their allies and partners in the Middle East, and the international community."

In the statement, which is endorsed by former U.S. nuclear negotiators, former senior U.S. nonproliferation officials, a former director-general of the International Atomic Energy Agency (IAEA), a former member of the UN Panel of Experts on Iran, and leading nuclear specialists from the United States and around the globe, the experts "… urge the leaders of the P5+1 states, the European Union, and Iran to take the steps necessary to ensure timely implementation and rigorous compliance with the Joint Comprehensive Plan of Action.”

The statement concludes: “… we believe the JCPOA meets key nonproliferation and security objectives and see no realistic prospect for a better nuclear agreement."

The agreement, which was negotiated by the P5+1 and Iran and has been approved by the UN Security Council, will be voted on by the U.S. Congress in September. The JCPOA will establish long-term, verifiable restrictions on Iran's sensitive nuclear fuel cycle activities, many of which will last for 10 years, some for 15 years, some for 25 years, with enhanced IAEA monitoring under Iran's additional protocol agreement with the IAEA and modified code 3.1 safeguards provisions lasting indefinitely.

“This statement from more than 70 of the world’s leading nonproliferation specialists underscores, as President Barack Obama recently noted, the majority of arms control and non-proliferation experts support the P5+1 and Iran nuclear deal,” said Daryl G. Kimball, executive director of the Arms Control Association, which organized the nonproliferation specialists' statement.

The Comprehensive P5+1 Nuclear Agreement With Iran:
A Net-Plus for Nonproliferation
 
Statement from Nuclear Nonproliferation Specialists
August 17, 2015

 
The Joint Comprehensive Plan of Action (JCPOA) is a strong, long-term, and verifiable agreement that will be a net-plus for international nuclear nonproliferation efforts. 
 
It advances the security interests of the P5+1 nations (China, France, Germany, Russia, the United Kingdom, and the United States), the European Union, their allies and partners in the Middle East, and the international community.
 
When implemented, the JCPOA will establish long-term, verifiable restrictions on Iran's enrichment facilities and research and development, including advanced centrifuge research and deployment. Taken in combination with stringent limitations on Iran’s low-enriched uranium stockpile, these restrictions ensure that Iran’s capability to produce enough bomb-grade uranium sufficient for one weapon would be extended to approximately 12 months for a decade or more.
 
Moreover, the JCPOA will effectively eliminate Iran’s ability to produce and separate plutonium for a nuclear weapon for at least 15 years, including by permanently modifying the Arak reactor, Iran’s major potential source for weapons grade plutonium, committing Iran not to reprocess spent fuel, and shipping spent fuel out of the country.
 
The JCPOA is effectively verifiable. The agreement will put in place a multi-layered monitoring regime across Iran’s entire nuclear supply chain, including centrifuge manufacturing sites (for 20 years), uranium mining and milling (for 25 years), and continuous monitoring of a larger number of nuclear and nuclear-related sites.
 
The JCPOA requires Iran to implement and ratify the additional protocol to Iran’s comprehensive safeguards agreement, which significantly enhances the International Atomic Energy Agency’s (IAEA) inspection regime. Among other measures, this will give international inspectors timely access to any Iranian facility of proliferation concern, including military sites, which the JCPOA will ensure cannot be stalled more than 24 days without serious consequences.
 
In addition, the JCPOA puts in place safeguards that require early notification of design changes or new nuclear projects by Iran (the modified code 3.1 provision). The additional protocol and code 3.1 monitoring and verification measures will remain in place indefinitely.
 
The JCPOA also requires that Iran cooperate with the IAEA to conclude its long-running investigation of Iran's past activities with possible military dimensions (PMDs) and permanently prohibits certain dual-use activities, which could contribute to the design and development of a nuclear explosive device.
 
Taken together, these rigorous limits and transparency measures will make it very likely that any future effort by Iran to pursue nuclear weapons, even a clandestine program, would be detected promptly, providing the opportunity to intervene decisively to prevent Iran from acquiring a nuclear weapon.
 
The agreement requires that Iran undertake major steps—including to reduce its uranium enrichment capacity, modify the Arak reactor, allow for more intrusive international monitoring, and cooperate with the IAEA’s PMD investigation—before UN Security Council, U.S., and EU economic and financial sanctions are suspended or terminated, and it provides for swift consequences in the event of noncompliance.
 
If all sides comply with and faithfully implement their multi-year obligations, the agreement will reduce the risk of a destabilizing nuclear competition in a troubled region – giving time and space to address other regional problems without fear of an Iran armed with nuclear weapons—and head off a catastrophic military conflict over Iran's nuclear program.
 
Though all of us could find ways to improve the text, we believe the JCPOA meets key nonproliferation and security objectives and see no realistic prospect for a better nuclear agreement.
 
We urge the leaders of the P5+1 states, the European Union, and Iran to take the steps necessary to ensure timely implementation and rigorous compliance with the JCPOA.
