Open Letters in Support of Deal: Scientists, Generals & Ambassadors

Groups of scientists, nonproliferation specialists, former generals and former ambassadors have authored open letters in support of the nuclear deal between Iran and the world’s six major powers. One group of former generals has also written an open letter.

On August 8, 29 top U.S. scientists wrote to President Barack Obama in support of the Iran nuclear deal. The “innovative agreement” has “much more stringent constraints than any previously negotiated non-proliferation framework,” according to the co-signers, who include six Nobel laureates, nuclear experts and former White House advisers. The following is the complete text.

Dear Mr. President,
As scientists and engineers with understanding of the physics and technology of nuclear power and of nuclear weapons, we congratulate you and your team on the successful completion of the negotiations in Vienna. We consider that the Joint Comprehensive Plan of Action (JCPOA) the United States and its partners negotiated with Iran will advance the cause of peace and security in the Middle East and can serve as a guidepost for future non-proliferation agreements.
This is an innovative agreement, with much more stringent constraints than any previously negotiated non-proliferation framework. It limits the level of enrichment of the uranium that Iran can produce, the amount of enriched uranium it can stockpile, and the number and kinds of centrifuges it can develop and operate. The agreement bans reconversion and reprocessing of reactor fuel, it requires Iran to redesign its Arak research reactor to produce far less plutonium than the original design, and specifies that spent fuel must be shipped out of the country without the plutonium being separated and before any significant quantity can be accumulated.
A key result of these restrictions is that it would take Iran many months to enrich uranium for a weapon. We contrast this with the situation before the interim agreement was negotiated in Lausanne: at that time Iran had accumulated enough 20 percent enriched uranium that the required additional enrichment time for weapons use was only a few weeks.
The JCPOA also provides for innovative approaches to verification, including monitoring of uranium mining, milling, and conversion to hexafluoride. Centrifuge manufacturing and R&D will be monitored as well. For 15 years the Natanz facility will be the only location where uranium enrichment is allowed to take place and it will be outfitted with real-time monitoring to assure rapid notice of any violation. The authority is provided for real-time monitoring of spent fuel as well.
Concerns about clandestine activities in Iran are greatly mitigated by the dispute resolution mechanism built into the agreement. The 24-day cap on any delay to access is unprecedented, and will allow effective challenge inspection for the suspected activities of greatest concern: clandestine enrichment, construction of reprocessing or reconversion facilities, and implosion tests using uranium. The approach to resolving “Possible Military Dimensions” is innovative as well: the International Atomic Energy Agency (IAEA) must be satisfied that it is fully informed about any previous activities, in order to guide its future verification plans, but Iran need not be publicly shamed. This agreement, also for the first time, explicitly bans nuclear weapons R&D, rather than only their manufacture as specified in the text of the Non-Proliferation Treaty (NPT).
Some have expressed concern that the deal will free Iran to develop nuclear weapons without constraint after ten years. In contrast we find that the deal includes important long-term verification procedures that last until 2040, and others that last indefinitely under the NPT and its Additional Protocol. On the other hand, we do believe that it would be valuable to strengthen these durable international institutions. We recommend that your team work with the IAEA to gain agreement to implement some of the key innovations included in the JCPOA into existing safeguards agreements. This will reduce the proliferation risks associated with national fuel cycle facilities worldwide. Thus in the future, when Iran is treated the same as all non-nuclear weapons states with nuclear energy programs, all such programs will be more stringently constrained and verified.
As you have stated, this deal does not take any options off the table for you or any future president. Indeed it will make it much easier for you or a future president to know if and when Iran heads for a bomb, and the detection of a significant violation of this agreement will provide strong, internationally supported justification for intervention.
In conclusion, we congratulate you and your team on negotiating a technically sound, stringent and innovative deal that will provide the necessary assurance in the coming decade and more that Iran is not developing nuclear weapons, and provides a basis for further initiatives to raise the barriers to nuclear proliferation in the Middle East and around the globe.

On July 16, more than 100 former U.S. ambassadors sent the following letter to President Obama in support of the agreement:
Letter to the President from over 100 former American Ambassadors on the Joint Comprehensive Plan of Action on Iran’s Nuclear Program
Dear Mr. President:
The Joint Comprehensive Plan of Action (JCPOA) with Iran stands as a landmark agreement in deterring the proliferation of nuclear weapons. If properly implemented, this comprehensive and rigorously negotiated agreement can be an effective instrument in arresting Iran’s nuclear program and preventing the spread of nuclear weapons in the volatile and vitally important region of the Middle East. Without your determination and the admirable work of Secretary of State Kerry and his team, this agreement would never have been reached.
As former American diplomats, we have devoted much of our lives to ensuring that the President had available the best possible diplomatic approaches to dealing with challenges to our nation’s security, even while recognizing that a strong military is essential to help the President and the Congress to carry out their duties to protect the nation and its people. Effective diplomacy backed by credible defense will be critically important now, during the period of inspection and verification of Iran’s compliance with the agreement.
The JCPOA touches on some of America’s most important national objectives: non proliferation and the security of our friends in the Middle East particularly Israel. Ensuring the cooperation and implementation of this agreement by a hostile nation will require constant, dedicated U.S. leadership and unflagging attention.
We recognize that the JCPOA is not a perfect or risk-free settlement of this problem. However, we believe without it, the risks to the security of the United States and our friends and allies would be far greater. We are satisfied that the JCPOA will put in place a set of constraints and inspections that can assure that Iran’s nuclear program during the terms of the agreement will remain only for peaceful purposes and that no part of Iran is exempt from inspection. As with any negotiated settlement, the most durable and effective agreement is one that all sides will commit to and benefit from over the long term.
We support close Congressional involvement in the oversight, monitoring and enforcement of this agreement. Congress must be a full partner in its implementation and must evaluate carefully the value and feasibility of any alternative that would claim better to protect U.S. security and more effectively to prevent Iran from acquiring a nuclear weapon. In particular, Congress must give careful attention to evaluating whether alternatives would be more or less likely to narrow the options for resolving this issue without the use of force.
In our judgment the JCPOA deserves Congressional support and the opportunity to show it can work. We firmly believe that the most effective way to protect U.S. national security, and that of our allies and friends is to ensure that tough-minded diplomacy has a chance to succeed before considering other more costly and risky alternatives.

On August 11, three dozen retired generals and admirals released the following letter:
The Iran Deal Benefits U.S. National Security
An Open Letter from Retired Generals and Admirals
On July 14, 2015, after two years of intense international negotiations, an agreement was announced by the United States, the United Kingdom, France, Germany, China and Russia to contain Iran’s nuclear program. We, the undersigned retired military officers, support the agreement as the most effective means currently available to prevent Iran from obtaining nuclear weapons.
The international deal blocks the potential pathways to a nuclear bomb, provides for intrusive verification, and strengthens American national security. America and our allies, in the Middle East and around the world, will be safer when this agreement is fully implemented. It is not based on trust; the deal requires verification and tough sanctions for failure to comply.
There is no better option to prevent an Iranian nuclear weapon. Military action would be less effective than the deal, assuming it is fully implemented. If the Iranians cheat, our advanced technology, intelligence and the inspections will reveal it, and U.S. military options remain on the table. And if the deal is rejected by America, the Iranians could have a nuclear weapon within a year. The choice is that stark.
We agree with the Chairman of the Joint Chiefs of Staff, General Martin Dempsey, who said on July 29, 2015, “[r]elieving the risk of a nuclear conflict with Iran diplomatically is superior than trying to do that militarily.”
If at some point it becomes necessary to consider military action against Iran, gathering sufficient international support for such an effort would only be possible if we have first given the diplomatic path a chance. We must exhaust diplomatic options before moving to military ones.
For these reasons, for the security of our Nation, we call upon Congress and the American people to support this agreement.

On August 26, an open letter from nearly 200 retired generals and admirals who oppose the deal was published. It was addressed to Speaker of the House John A. Boehner, Minority Leader Nancy Pelosi, Senate Majority Leader Mitch McConnell and Senate Minority Leader Harry Reid.  
Letter to Congressional Leadership from Nearly 200 Retired Generals and Admirals
Dear Representatives Boehner and Pelosi and Senators McConnell and Reid:
As you know, on July 14, 2015, the United States and five other nations announced that a Joint Comprehensive Plan of Action (JCPOA) has been reached with Iran to prevent it from developing nuclear weapons. In our judgment as former senior military officers, the agreement will not have that effect. Removing sanctions on Iran and releasing billions of dollars to its regime over the next ten years is inimical to the security of Israel and the Middle East. There is no credibility within JCPOA’s inspection process or the ability to snap back sanctions once lifted, should Iran violate the agreement. In this and other respects, the JCPOA would threaten the national security and vital interests of the United States and, therefore, should be disapproved by the Congress.
The agreement as constructed does not “cut off every pathway” for Iran to acquire nuclear weapons. To the contrary, it actually provides Iran with a legitimate path to doing that simply by abiding by the deal. JCPOA allows all the infrastructure the Iranians need for a nuclear bomb to be preserved and enhanced. Notably, Iran is allowed to: continue to enrich uranium; develop and test advanced centrifuges; and continue work on its Arak heavy-water plutonium reactor. Collectively, these concessions afford the Iranians, at worst, a ready breakout option and, at best, an incipient nuclear weapons capability a decade from now.
The agreement is unverifiable. Under the terms of the JCPOA and a secret side deal (to which the United States is not privy), the International Atomic Energy Agency (IAEA) will be responsible for inspections under such severe limitations as to prevent them from reliably detecting Iranian cheating. For example, if Iran and the inspectors are unable to reach an accommodation with respect to a given site, the result could be at least a 24-day delay in IAEA access. The agreement also requires inspectors to inform Iran in writing as to the basis for its concerns about an undeclared site, thus further delaying access. Most importantly, these inspections do not allow access to Iranian military facilities, the most likely location of their nuclear weapons development efforts. In the JCPOA process, there is substantial risk of U.S. intelligence being compromised, since the IAEA often relies on our sensitive data with respect to suspicious and/or prohibited activity.
While failing to assure prevention of Iran’s nuclear weapons development capabilities, the agreement provides by some estimates $150 billion dollars or more to Iran in the form of sanctions relief. As military officers, we find it unconscionable that such a windfall could be given to a regime that even the Obama administration has acknowledged will use a portion of such funds to continue to support terrorism in Israel, throughout the Middle East and globally, whether directly or through proxies. These actions will be made all the more deadly since the JCPOA will lift international embargoes on Iran’s access to advanced conventional weapons and ballistic missile technology.
In summary, this agreement will enable Iran to become far more dangerous, render the Mideast still more unstable and introduce new threats to American interests as well as our allies. In our professional opinion, far from being an alternative to war, the Joint Comprehensive Plan of Action makes it likely that the war the Iranian regime has waged against us since 1979 will continue, with far higher risks to our national security interests. Accordingly, we urge the Congress to reject this defective accord.

On August 17, more than 70 of the world’s leading nuclear nonproliferation specialists issued the following joint statement in support of the deal.

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.
