U.S. Decision to Cease Implementing the Iran Nuclear Agreement

May 9, 2018 (R44942)
Jump to Main Text of Report



On May 8, 2018, President Donald Trump announced that his Administration would cease implementing U.S. commitments under the 2015 multilateral Joint Comprehensive Plan of Action (JCPOA) with Iran and reimpose all U.S. sanctions that were in place prior to the JCPOA. His announcement made reference to his previous statements on the issue, including an October 13, 2017, announcement of U.S. strategy on Iran and a January 12, 2018, statement pledging to leave the agreement unless Congress and U.S. allies acted to address the full range of U.S. concerns on Iran. In his May 8 and earlier statements, President Trump asserted that the agreement does not address the full range of potential threats posed by Iran, or permanently ensure that Iran cannot develop a nuclear weapon. President Trump also again asserted that the JCPOA provided Iran with additional financial resources with which to pursue its ballistic missile program and support its regional "malign activities." In his May 8 statement, President Trump indicated that reimposed U.S. sanctions would succeed in pressuring Iran to renegotiate the JCPOA to accommodate Administration demands.

President Trump's May 8 statement also implied that, based on an early May presentation by Israeli Prime Minister Benjamin Netanyahu, Iran has not abandoned an intent to ultimately develop a nuclear weapon. International nuclear inspectors, as well as senior U.S. officials, have consistently indicated in their reports that Iran is complying with the provisions of the JCPOA. The President foreshadowed his May 8 announcement with his October 2017 and January and April 2018 refusal to certify to Congress, under the Iran Nuclear Agreement Review Act (INARA, P.L. 114-17), that continued U.S. sanctions relief to Iran under the JCPOA is "appropriate and proportionate" to the measures taken by Iran to terminate its illicit nuclear program. The withholding of that certification did not automatically reimpose any U.S. sanctions on Iran, but gave Congress the opportunity to use expedited procedures to do so. Congress did not act to reimpose the sanctions.

The other powers that negotiated the accord with Iran—Russia, China, France, Britain, and Germany—have consistently asserted that the JCPOA is succeeding in its core objectives and that its implementation should not be jeopardized. Several European countries have sought to address President Trump's demands in negotiations with U.S. officials. In late April 2018 visits to Washington, DC, the President of France and the Chancellor of Germany told President Trump they want to work with the United States to formulate joint action that would address his concerns, but they urged that he keep the United States in the accord as a foundation on which to build additional restrictions on Iran. The leaders of Britain, France, and Germany, as well as the European Union, expressed "regret" about the U.S. decision and pledged to work with Iran to continue implementing the JCPOA. Iran's President Hassan Rouhani immediately reacted to the May 8 U.S. decision by pledging to continue implementing the accord, provided Iran continues to receive the economic benefits of the agreement.

U.S. Decision to Cease Implementing the Iran Nuclear Agreement

Overview of the Issue

In October 2017 and more explicitly in January 2018, the President linked continued U.S. participation in the Joint Comprehensive Plan of Action (JCPOA) to congressional and allied action to address the deficiencies in the JCPOA that the President identified. On May 8, he announced that the United States would cease implementing the JCPOA, using the mechanism of reimposing suspended U.S. sanctions to implement the U.S. pullout. The May 8 announcement came in advance of a May 12, 2018, date when the existing waiver of a key U.S. sanctions law was to expire. The U.S. withdrawal from the JCPOA will likely have significant implications for U.S. policy in the region.

This report bases its analysis primarily on the text of key documents involved in the issue—the JCPOA itself;1 U.N. Security Council Resolution 2231 of July 20, 2015,2 which endorsed the JCPOA; and the Iran Nuclear Agreement Review Act (INARA, P.L. 114-17, of May 22, 2015).

Presidential Decision to Cease Implementing the JCPOA

The JCPOA does not specifically provide for any party to the agreement to "withdraw."3 Although European and other diplomats argue that Resolution 2231 makes the agreement binding on all parties under the U.N. Charter, officials in the Obama Administration asserted that the JCPOA is a nonbinding political commitment,4 and Trump Administration officials continued that assertion. As President Trump noted in his October 2017 and January 2018 statements, he has the authority to cease U.S. implementation of the accord. He has the authority to reimpose all or some of the U.S. sanctions that were revoked or suspended to implement the deal, to reinstate those sanctions imposed by Executive Order, and to redesignate for sanctions entities that were "de-listed" from sanctions to implement the JCPOA. The President's May 8, 2018, announcement that the United States would no longer implement the JCPOA indicated that he would exercise all these options to reimpose all U.S. sanctions that were revoked or suspended to implement the JCPOA. The President apparently does not require the approval of Congress for these courses of action.

President Trump's May 8 announcement was widely foreshadowed. On August 1, 2017, then-Secretary of State Tillerson told a press briefing: "The conversation on Iran does not begin and end with the JCPOA, the nuclear agreement, and I think if there's one thing I hope I can help people understand it's that agreement dealt with a very small slice of Iran's threats, and that was their nuclear program."5 In a speech to the U.N. General Assembly on September 19, 2017, President Trump said

We cannot let a murderous regime continue these destabilizing activities while building dangerous missiles, and we cannot abide by an agreement if it provides cover for the eventual construction of a nuclear program. The Iran Deal was one of the worst and most one-sided transactions the United States has ever entered into. Frankly, that deal is an embarrassment to the United States, and I don't think you've heard the last of it, believe me.6

On October 13, 2017, President Trump announced a new U.S. strategy on Iran,7 following a six-month policy review. The President raised the possibility that he might terminate U.S. participation in the JCPOA if certain conditions are not met, stating that

By its own terms, the Iran Deal was supposed to contribute to "regional and international peace and security." And yet, while the United States adheres to its commitment under the deal, the Iranian regime continues to fuel conflict, terror, and turmoil throughout the Middle East and beyond. Importantly, Iran is not living up to the spirit of the deal.... That is why I am directing my administration to work closely with Congress and our allies to address the deal's many flaws so that the Iranian regime can never again threaten the world with nuclear weapons.... However, in the event we are not able to reach a solution working with Congress and our allies then the agreement will be terminated. It is under continuous review, and our participation can be cancelled by me, as President, at any time.

On January 12, 2018, President Trump again threatened to withdraw the United States from the JCPOA unless Congress and the European allies "fix the terrible flaws of the Iran nuclear deal."8 He identified the "fixes" as (1) a requirement that Iran allow immediate inspections at all sites requested by international inspectors; (2) ensuring that Iran "never even comes close to possessing a nuclear weapon"; (3) the elimination of an expiration date for the JCPOA's nuclear restrictions on Iran; and (4) subjecting Iran's development and testing of missiles to "severe sanctions." The President also called on U.S. allies to "take stronger steps with us to confront Iran's other malign activities," defined as Iran's support for terrorist groups, its development of missiles and their supply to Iran's allies and proxies, Iran's cyber threats, its human rights violations, and its threats to international shipping.

After the January 12, 2018, statement, the President replaced Tillerson and National Security Adviser H.R. McMaster with officials who have been critics of the JCPOA. Secretary of State Mike Pompeo, sworn in on April 26, 2018, and National Security Adviser John Bolton, who began his appointment on April 9, 2018, both, prior to assuming their current posts, argued in favor of military action against Iran's nuclear program and for U.S. efforts to change Iran's regime.

The May 8 announcement signaled that the Administration seeks to encourage further efforts to address its concerns about the JCPOA and broader Iran issues, possibly in a revised nuclear agreement. According to the May 8 statement

As we exit the Iran deal, we will be working with our allies to find a real, comprehensive, and lasting solution to the Iranian nuclear threat. This will include efforts to eliminate the threat of Iran's ballistic missile program, to stop its terrorist activities worldwide, and to block its menacing activity across the Middle East.... Iran's leaders will naturally say that they refuse to negotiate a new deal. They refuse, and that's fine. I'd probably say the same thing if I was in their position. But the fact is, they are going to want to make a new and lasting deal, one that benefits all of Iran and the Iranian people.9

Reaction to the Announcement

Global reaction to the May 8 announcement tracked closely with the consistent positions taken by countries and leaders on the JCPOA. The decision drew statements of support from Israel, Saudi Arabia, the United Arab Emirates, and Bahrainall countries that assert that Iran is a major threat to their security.

European Reaction and Plans

The leaders of France, Germany, and Britain (the three European countries that negotiated the JCPOA alongside the United States)—as well as the EU collectivelyissued a joint statement expressing "regret" over the decision. European leaders stated that they remained committed to the JCPOA as "important for our joint security." European diplomats have consistently asserted that the JCPOA is a binding international commitment under Resolution 2231, which endorsed the accord.

The European reaction appeared to reflect disappointment in the failure of their efforts to address President Trump's concerns through a supplemental agreement or pledges of joint action. Since President Trump's October 13, 2017, speech, Britain, France, and Germany held numerous meetings with U.S. State Department officials led by senior adviser to the Secretary of State Brian Hook, to discuss potential European steps that could satisfy Mr. Trump's demands. As the May 12 deadline to again waive key sanctions laws loomed, France's President Emmanuel Macron and Germany's Chancellor Angela Merkel each met with President Trump in Washington, DC, during the week of April 23, expressing support for working with the United States on additions to the JCPOA, or other U.S.-European joint action, that would address the expiration of nuclear restrictions, Iran's regional activities, and Iran's ballistic missile programs. President Macron's comments during his visit suggested he might be willing to try to engage Iran (and presumably also Russia and China) in new negotiations regarding these issues.10 Yet, no firm agreements were announced in the course of the European leadership visits. The European leaders indicated that it would be unwise to risk the collapse of the accord without a clear alternative in place, and both indicated they intended to continue implementing the JCPOA even if President Trump ceases to implement it. According to a senior State Department official briefing reporters after the May 8 presidential announcement

The President made clear on January 12th that he was giving a certain number of months to try to—for—try to get a supplemental agreement with the E3 (Britain, France, and Germany). We didn't get there. We got close. We made a—we had movement, a ton of good progress, which will not be wasted, but we didn't get there.... 11

Iranian Reaction and Plans

Iran's President Hassan Rouhani reacted to the May 8 announcement immediately, stating that Iran would work with the remaining parties to the accord to keep it intact. He indicated that Iran would continue to implement its commitments as long as Iran derives the economic benefits of the agreement, an implicit threat that Iran might leave the accord if reimposed U.S. sanctions damage its economy significantly. Paragraph 26 of the JCPOA states that "... Iran has stated that it will treat such a reintroduction or reimposition of the sanctions specified in Annex II, or such an imposition of new nuclear-related sanctions, as grounds to cease performing its commitments under this JCPOA in whole or in part."12 At the same time, on May 8, Rouhani directed Iran's nuclear program officials to be prepared to restart suspended aspects of Iran's program if the accord collapses entirely.

Iranian officials have consistently insisted that they would not renegotiate the JCPOA under any circumstances. Iranian hardliners are likely to oppose any such renegotiation as a capitulation and Iran's leaders have argued that no amount of U.S. or international pressure will cause Iran to cede what it views as its right to have a civilian nuclear program or the ballistic missile programs Iran says are needed to defend itself. Yet, in late 2017, some Iranian military figures suggested Iran might be willing to refrain from developing missiles with ranges over the 1,200 mile ranges of Iran's existing missile arsenal. On May 9, Iranian parliamentarians burned copies of the JCPOA and chanted anti-U.S. slogans in Iran's parliament chamber to express opposition to the U.S. decision.

Possible Congressional Responses

As noted above, President Trump has called on Congress to act on new legislation that addresses the weaknesses of the JCPOA. On October 13, 2017, Senate Foreign Relations Committee Chairman (SFRC) Bob Corker and Senator Tom Cotton released an outline of legislation that would address some of the President's concerns by setting up a trigger to automatically reimpose U.S. sanctions at any time that Iran violates existing JCPOA nuclear restrictions—even after the restrictions expire under the JCPOA. The legislation was not introduced. Another version, reportedly negotiated between Senator Corker and SFRC ranking member Senator Robert Menendez, also was not introduced. Senator Corker indicated in a press interview on April 29, 2018, that Congress might act to address President Trump's concerns about the JCPOA if European leaders support joint action on the JCPOA even if doing so might appear to contradict the provisions of the JCPOA.13 This suggests that congressional action might hinge on whether European leaders are able to forge a new agreement with Iran or a U.S.-European agreement that would convince President Trump to resume implementing the existing JCPOA.

Use of JCPOA Provisions

The Trump Administration could have used provisions of the JCPOA itself to cease implementation of U.S. commitments under the agreement. It opted not to do so, but instead to cease implementing the JCPOA by reimposing U.S. sanctions (see below). Paragraph 36 of the JCPOA outlines a complex "Dispute Resolution Mechanism" under which any party to the agreement can assert that another party is violating the accord and seek to resolve the issue. The JCPOA mechanism outlines a process by which Iran can resolve such a dispute but provides that, "if the complaining participant deems the issue to constitute significant nonperformance, then that participant could treat the unresolved issue as grounds to cease performing its commitments under this JCPOA.... "14 The dispute resolution mechanism provides for the United States to be able to "snap back" all sanctions.15 The United States is a veto-wielding permanent member of the U.N. Security Council, and the dispute resolution mechanism enables any veto-wielding member to block a U.N. Security Council resolution that would continue the lifting of U.N. sanctions.

The dispute resolution mechanism generally refers to the ability of any party to complain about potential nonperformance of only those issues that are directly addressed in the JCPOA. A U.S. accusation of Iranian noncompliance, in the absence of supporting evidence from the International Atomic Energy Agency (IAEA), would undoubtedly raise questions about the use of this mechanism to leave the agreement.

Iranian Compliance with the JCPOA

On January 16, 2016, IAEA Director General Yukiya Amano reported to the agency's Board of Governors that Iran had implemented the nuclear measures required for the JCPOA's "Implementation Day." The agency has continued to monitor Iranian compliance with the agreement's nuclear-related requirements; all subsequent reports, the most recent of which Amano issued on February 22, 2018, document Iranian compliance with these obligations.16 Although the IAEA reports findings of its inspection and monitoring activities and the JCPOA-established Joint Commission monitors the parties' implementation of the agreement, compliance determinations are national decisions. Department of State Director of Policy Planning Brian Hook told reporters on March 21 that Iran is in "compliance with their commitments under the JCPOA"—a reiteration of past U.S. assessments.

Although these reports and U.S. official statements and certifications indicate that Iran has not engaged in any JCPOA- prohibited activities, the agreement describes arrangements for agency inspectors to gain access to Iranian sites, including military sites, other than those that Tehran has declared to the agency, "if the IAEA has concerns regarding undeclared nuclear materials or activities, or activities inconsistent with" the JCPOA. Should such concerns arise, the IAEA is to "provide Iran the basis for such concerns and request clarification." The IAEA could request access to the site if Iran's explanation does not sufficiently clarify the matter. The JCPOA provides for a process to resolve the issue in question if Tehran initially declines to provide access to the site. Iran allowed the IAEA to visit the Parchin military site in September 2015 as part of an agreed process for resolving IAEA concerns about possible past Iranian military-related nuclear activities.

Amano's February 2018 report states that the IAEA has continued verification and monitoring of the restrictions described in Section T of the JCPOA, which prohibits a number of nuclear-weapons-related activities.17 The IAEA has not reported whether it has requested access to any Iranian military facilities, but the agency has a number of methods other than inspections, such as analyzing open source information and receiving intelligence briefings from governments, to monitor Iranian compliance with these and other JCPOA commitments. Amano stated in a March 5 address to the IAEA board that agency inspectors "have had access to all the sites and locations which we needed to visit."

U.S. officials have expressed concern regarding Iran's accumulation of heavy water. According to the JCPOA, Iran has committed to refrain from accumulating heavy water "beyond Iran's needs"—an amount which the JCPOA specified is 130 metric tons of "nuclear grade heavy water or its equivalent in different enrichments" prior to commissioning the redesigned Arak reactor. Tehran is to "sell any remaining heavy water on the international market for 15 years." Iran's stock of heavy water has exceeded 130 metric tons on two occasions since the JCPOA began implementation. On February 17, 2016, the IAEA verified that Tehran's heavy water stock had exceeded 130 metric tons; on November 8, 2016, the IAEA verified that Iran's stock of heavy water had again exceeded the JCPOA limit. Iran resolved the issue on both occasions by exporting the excess heavy water. Iran has sent this material to Russia and the United States, shipping at least some of it via Oman. The IAEA verified on February 11, 2018, that Iran had 117.9 metric tons of heavy water.18

Use of INARA Provisions

The INARA law gives the Administration options to cease U.S. implementation of the JCPOA. However, the May 8 presidential statement on the JCPOA did not invoke INARA provisions, but instead was based on presidential authority to reimpose those sanctions that were suspended.

Material Breach Report

INARA authorizes the President to provide Congress with "credible and accurate information relating to a potentially significant breach or compliance incident by Iran ..." and, within 30 days of submitting such information, to determine whether the Iranian breach "constitutes a material breach" and whether Iran has "cured such material breach."19 Under INARA, an Administration confirmation of an uncured material breach of the JCPOA by Iran would trigger expedited procedures for congressional consideration of legislation that would reimpose those U.S. sanctions that have been waived to implement the JCPOA—and prevent further such waivers. A summary of the expedited procedures is provided in the text box, "Expedited Congressional Procedures," at the end of this report.

An Administration report to Congress of a material breach by Iran would almost certainly prompt other P5+1 parties to question whether U.S. assertions are corroborated by similar findings by the IAEA. The INARA material breach report does not appear to provide for the Administration to accuse Iran of an uncured breach on any grounds other than compliance with the nuclear commitments of the JCPOA. Other P5+1 parties might also question whether the United States has provided information on any potential Iranian breach to the IAEA for further investigation under the dispute resolution mechanism discussed above. If the Administration has not provided such information to the IAEA for investigation, its not doing so would likely raise questions about the credibility of the information or the motives of the Administration in reporting such accusations to Congress separately.20

Compliance Certification Decisions

INARA requires the Administration to certify every 90 days that all of 4 main conditions of Iranian compliance have been met. The four points are that (1) Iran is verifiably and fully implementing the JCPOA; (2) Iran has not committed an uncured material breach; (3) Iran has not taken any action that could advance a nuclear weapons program; and (4) continued suspension of sanctions (including issuance of waivers of applicable sanctions laws) is (a) appropriate and proportionate to the specific and verifiable measures taken by Iran with respect to terminating its illicit nuclear program and (b) vital to the national security interests of the United States.

A decision on INARA certification is separate from a presidential decision whether to reimpose sanctions. INARA gives Congress the option to reimpose sanctions on Iran under expedited privileges, but does not require such action. INARA contains a provision under which sanctions reimposed by the INARA process cannot be waived or otherwise not implemented by the President.

In his October 13, 2017, speech on Iran, President Trump announced that he was withholding INARA compliance certification on the grounds that he cannot certify that continued sanctions relief is "appropriate and proportionate" to the measures taken by Iran to terminate its illicit nuclear program. Explaining this decision, the President argued that the JCPOA provided "urgently needed relief from the intense domestic pressure the sanctions had created" and also allowed Iran to "sprint towards a rapid nuclear weapons breakout" after the time-bound restrictions on Iran's nuclear program end. President Trump also asserted that Iran has not complied with the "spirit" of the agreement and has violated some JCPOA nuclear-related provisions. The President used the same grounds to withhold certification at the certification deadline of January 13, 2018. The absence of certification continued at the subsequent certification decision deadline of April 13, 2018.

As discussed in the text box below, the refusal to certify Iranian compliance gave Congress the option to act under expedited procedures to reimpose sanctions on Iran. Congress has not taken such action, to date.

Sanctions Waiver Decisions

Separately from INARA, the President has the option to reimpose sanctions by refusing to renew waivers of the various sanctions laws, reissuing Executive Orders that were revoked, or imposing new sanctions by executive order.21 A refusal to certify Iranian compliance under INARA does not automatically cause the reimposition of any Iran sanctions. On May 8, President Trump announced that he was withdrawing from the JCPOA by using his authority to reimpose all sanctions that were suspended or revoked. The sanctions, to go fully back into effect by no later than November 6, 2018 (180 days from May 8), are analyzed in significant detail in CRS Report RS20871, Iran Sanctions, by [author name scrubbed]. The May 8 statement was in advance of the May 12 expiration of the waiver in place for the FY2012 NDAA (120-day waiver period). The waivers of the other 3 laws that were waived were scheduled to expire in mid-July 2018 (180-day/6-month waiver periods). Prior to the May 8 announcement, the President had renewed the waivers when they have come up for renewal—most recently on January 12, 2018.

As part of the process of reimposing all Iran sanctions, the Administration will be restoring the "Specially Designated National" (SDN) designation to all of the entities that were "de-listed" to implement the JCPOA. The entities that were de-listed are those that involve Iran's civilian economy, such as banks, shipping firms, insurance entities, civilian manufacturers, and energy-related entities. Redesignating such entities resumes the application of some U.S. secondary sanctions to those entities, including provisions of the Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010 (CISADA, P.L. 111-195) or the Iran Freedom and Counter-Proliferation Act (IFCA, P.L. 112-239), that largely close the U.S. economy to third-country entities that conduct transactions with Iran-related SDNs. The entities to be "re-listed" (at the 180-day mark, which is November 4, 2018) include those that are crucial to Iran's economy, such as the Central Bank of Iran, the Islamic Republic of Iran Shipping Lines (IRISL), Iran Air, and the National Iranian Oil Company (NIOC).

Expedited Congressional Procedures

In the absence of the required certification, or after a presidential determination of noncompliance or an uncured breach, a House or Senate party floor leader may introduce, within 60 calendar days, a bill (with stipulated text) to reinstate sanctions. The bill is subject to expedited congressional procedures (though each chamber could choose to use its existing procedures instead). Committees that are referred the bill are automatically discharged if it has not been reported after 10 legislative days (House) or session days (Senate).

In the House, on or after the third legislative day after reporting/discharge, a majority could agree to a nondebatable motion to bring up the bill. In the Senate, after reporting/discharge, a majority could agree to a nondebatable motion to bring up the bill; no cloture process, with its associated three-fifths vote threshold, is necessary for the Senate to do so.

House floor consideration is limited to two hours. The Senate limit on floor consideration is 10 hours; thus, a numerical majority could pass the bill without the need for three-fifths to first invoke cloture. (A majority could also agree to a nondebatable motion to spend less time on the bill.) Floor amendments are precluded in both chambers. Other procedures would expedite second-chamber consideration of a bill received from the other house.

A bill agreed to by both chambers is subject to presidential veto, which can be overridden by two-thirds vote in both chambers. (Senate consideration of the veto message is limited to 10 hours; no cloture process would be required to reach the override vote.)
