In an October 13, 2017, announcement of a new U.S. strategy on Iran, President Donald Trump asserted that the 2015 multilateral nuclear agreement with Iran, the Joint Comprehensive Plan of Action (JCPOA), does not address the full range of potential threats posed by Iran, or permanently ensure that Iran cannot develop a nuclear weapon. Trump asserted that, by supporting terrorist groups in the Middle East region and furthering its ballistic missile program, "Iran is not living up to the spirit of the deal." The President also announced that he would not 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.
In a January 12, 2018, statement, the President more explicitly threatened to reimpose U.S. sanctions on Iran, and thereby essentially withdraw the United States from the agreement, unlessIn his statement, the President asked Congress and U.S. allies to workacted to address the full range of U.S. concerns on Iran. The other powers that negotiated the accord with Iran—Russia, China, France, Britain, and Germany—assert that the JCPOA is succeeding in its core objectives and that its implementation should not be jeopardized. The President said that he might act under his own authority to extricate the United States from the JCPOA if Congress and U.S. allies fail to adequately address his concerns.
This report analyzes some Several European countries have sought to address at least some of President Trump's demands in negotiations with U.S. officials. However, consensus has been difficult to achieve and there is little certainty about what President Trump might accept in order to keep the United States in the agreement.
This report analyzes some of the options the Administration and Congress might use to end or alter U.S. implementation of the JCPOA. These options, which might involve use of procedures in the JCPOA itself or INARA, are not necessarily mutually exclusive. Some potentialPotential implications of these options are analyzed as well. For details on the JCPOA and related issues, see CRS Report R43333, Iran Nuclear Agreement, by [author name scrubbed] and [author name scrubbed]; and CRS Report RS20871, Iran Sanctions, by [author name scrubbed].
Press reports in August 2017 indicated that President Trump might not certify to Congress that all conditions for certification of compliance under the Iran Nuclear Agreement Review Act (INARA, P.L. 114-17)—which amended Section 135(d)(6) of the Atomic Energy Act of 1954 (42 U.S.C. 2160(e)—are being met.1 The certification requirements are related to, but separate from, Iran's nuclear obligations under certification requirement is not a specific provision of the July 14, 2015, multilateral nuclear agreement (Joint Comprehensive Plan of Action, JCPOA). The JCPOA was between Iran and the "P5+1" group of countries (United States, Russia, China, Britain, France, and Germany). On October 13, 2017, the President announced a new U.S. strategy on Iran, and stated that he would not be certifying Iranian compliance under INARA when the next certification was due on October 15, 2017.2
Although the withholding of certification does not automatically end U.S. participation in the JCPOA, the presidential statement has left unclear whether the United States would remain in the JCPOA over the long term. The President has linked continued U.S. participation to congressional and allied action to address the deficiencies in the JCPOA that the President identified in his October 13 statement. There are several mechanisms or methods the Administration might use to cease implementing the JCPOA or to alter its implementation. The JCPOA was between Iran and the "P5+1" group of countries (United States, Russia, China, Britain, France, and Germany).
This report bases its analysis primarily on the text of key documents involved in the issue—the JCPOA itself;3 U.N. Security Council Resolution 2231 of July 20, 2015,4 which endorsed the JCPOA; and the Iran Nuclear Agreement Review Act (INARA, P.L. 114-17, of May 22, 2015).
In October 2017 and again in January 2018, the President continued to waive provisions of the key U.S. sanctions laws that were waived to implement the JCPOA.
In October 2017 and more explicitly in January 2018, the President has linked continued U.S. participation to congressional and allied action to address the deficiencies in the JCPOA that the President has identified. Should congressional or allied action fail to satisfy the President, and should he decide to cease implementing the JCPOA, there are several mechanisms he might use. One mechanism—a reimposition of U.S. sanctions—could be employed as early as May 12, 2018, when the existing waiver of a key U.S. sanctions law expires. No matter the mechanism used, a U.S. withdrawal from the JCPOA would 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;3 U.N. Security Council Resolution 2231 of July 20, 2015,4 which endorsed the JCPOA; and the Iran Nuclear Agreement Review Act (INARA, P.L. 114-17, of May 22, 2015). The JCPOA does not specifically provide for any party to the agreement to "withdraw."5 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,6 and Trump Administration officials continue to make 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 and he could reimpose all or some of the U.S. sanctions that were revoked or suspended to implement the deal. He could reinstate those sanctions imposed by Executive Order, decline to continue waiving provisions of sanctions laws, or redesignate for sanctions entities that were "de-listed" from sanctions to implement the JCPOA. It is unlikely that the President would require the approval of Congress for these courses of action. 57 On September 5, 2017, U.S. Ambassador to the United Nations Nikki Haley addressed a Washington, DC, think tank, saying, "The truth is, the Iran deal [JCPOA] has so many flaws that it's tempting to leave it."68 In his speech to the U.N. General Assembly on September 19, 2017, President Donald 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.79
On October 13, 2017, President Trump announced a new U.S. strategy on Iran,810 based on a six-month policy review of all aspects of Iran policy, including the JCPOA. The President held out 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.
Since the January 12, 2018, presidential statement, the President has replaced Secretary of State Tillerson and National Security Adviser H.R. McMaster with nominees who have tended to emphasize strong U.S. responses to the threat posed by Iran. Secretary of State nominee Mike Pompeo, currently Director of the CIA, and new National Security Adviser John Bolton have both at times in their careers argued in favor of military action against Iran's nuclear program and for U.S. efforts to change Iran's regime. Both have been critical of the JCPOA and are viewed by many experts as less likely than their predecessors to try to dissuade President Trump from leaving the JCPOA.The President appears to be attempting to use potential U.S. nonparticipation in the JCPOA as leverage to garner the support of Congress and of other P5+1 governments to address key concerns, including the expiration of nuclear restrictions of the JCPOA, Iran's missile program, and Iran's support for regional armed factions. The latter two aspects of Iranian behavior are not addressed in the JCPOA, but are subject to restrictions by United Nations Security Council Resolution 2231. The Resolution requires that, for a maximum period ending in October 2020, any Iranian importation of specified weapons systems requires explicit approval of the Security Council and exportation of any On January 12, 2018, President Trump expanded his criticism of the JCPOA into an explicit threat to withdraw the United States from the JCPOA unless Congress and the European allies "fix the terrible flaws of the Iran nuclear deal."11 He identified the areas Congress and the Europeans must address 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." Those activities were 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.
, earlier than the maximum deadlines, upon a "Broader Conclusion" by the International Atomic Energy Agency (IAEA) that all nuclear material in Iran remains in peaceful activities.9 And, these12 These non-nuclear provisions of Resolution 2231 have not had significanthad limited effect: Iran has engaged in numerous ballistic missile tests since the JCPOA began implementation in January 2016. Both, and both Obama and Trump Administration officials have termed the tests as "defiant of" and "inconsistent with" the Resolution rather than outright violations. Iran continues to openly supply several governments and factions in the Middle East region with arms, appearing to clearly violate Resolution 2231.
The JCPOA does not specifically provide for any party to the agreement to "withdraw."10 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,11 and Trump Administration officials continue to make that assertion. As President Trump noted in his October 13 speech, he could announce a cessation of U.S. implementation of the accord and he could reimpose all or some of the U.S. sanctions that were revoked or suspended to implement the deal. He could reinstate those sanctions imposed by Executive Order, decline to continue waiving provisions of sanctions laws, or redesignate for sanctions entities that were "de-listed" from sanctions to implement the JCPOA. It is unlikely that the President would require the approval of Congress for these courses of action.
A decision to reimpose most or all U.S. sanctions would likely encounter criticism from officials of other JCPOA parties, as well as Iran. European Union diplomats view the JCPOA as a binding international commitment. In the immediate aftermath of President Trump's October 13 speech, Britain, France, and Germany (the three European countries that negotiated the JCPOA alongside the United States) issued a statement that "Preserving the JCPOA is in our shared national security interest," while expressing a willingness to work with the United States to address concerns about Iran's ballistic missile program and regional activities.12
European Union diplomats view the JCPOA as a binding international commitment, but several key European countries have sought to address President Trump's concerns in order to preserve the JCPOA. In the immediate aftermath of President Trump's October 13, 2017, speech, Britain, France, and Germany (the three European countries that negotiated the JCPOA alongside the United States) issued a statement that "Preserving the JCPOA is in our shared national security interest," while expressing a willingness to work with the United States to address concerns about Iran's ballistic missile program and regional activities.14 Subsequently, the three European countries have held meetings with U.S. State Department and other U.S. officials to discuss potential European steps that could satisfy Mr. Trump's demands. The European countries appear reluctant to commit to any steps that would explicitly require formal renegotiation or clearly contradict the JCPOA, but these sessions reportedly have produced some European commitments for sanctions on Iran's missile programs and efforts against Iran's regional malign activities.15 It is unclear whether the European commitments will succeed in persuading President Trump to remain in the accord. Officials of Russia and China have refused to discuss any renegotiation of the JCPOA or to take additional steps against Iran's non-nuclear activities. 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 under discussion by Senator Corker and SFRC ranking member Senator Robert Menendez, also has not been introduced. Some experts assess that legislation that would trigger reimposed sanctions after the JCPOA restrictions expire would amount to a violation of the JCPOA and prompt Iran to abrogate the accord. Iranian leaders indicate within the JCPOA how they would expect to react to a unilateral U.S. decision to reimpose those sanctions that were lifted or suspended. Paragraph 26 states. Iran continues to openly supply several governments and factions in the Middle East region with arms, possibly including, according to U.N. reports, short-range ballistic missiles.13 Such weapons shipments appear to constitute clear violations of Resolution 2231.
European Responses
13 Following President Trump's October 13, 2017 speech, Iranian President Hassan Rouhani stressed that Iran intended to remain in the JCPOA and to continue complying with it16 Iran's leaders state that they intend to remain in the JCPOA and to continue complying with it, although Iranian officials have also warned that they can easily reconstitute all aspects of Iran's nuclear program if a U.S. pullout causes the deal to collapse.
The Trump Administration could conceivably use provisions of the JCPOA itself to cease U.S. implementation of U.S. of its commitments under the agreement. 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.... "1417 The dispute resolution mechanism also provides for the United States to be able to "snap back" all U.N. sanctions that were in place prior to Implementation Day of the JCPOA (January 16, 2016).1518 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—and not issues that are not covered by the agreement, such as ballistic missilesmissile development or Iran's regional activities. The International Atomic Energy Agency (IAEA) is the international body that is charged with monitoring and verifying Iran's nuclear commitments. A U.S. accusation of Iranian noncompliance—in the absence of supporting evidence from the IAEA—would undoubtedly raise questions among other parties to the JCPOA about the U.S. accusations against Iranabout the use of this mechanism to leave the agreement. IAEA reports have consistently cited Iran as fully complying with the agreement. The text of the JCPOA dispute resolution mechanism does not address the ability of any JCPOA party to accuse another of violating non-nuclear aspects of the accord.

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 Although these reports and Tillerson's certification 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 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 |
The INARA law gives the Administration a number of options to cease or alter U.S. implementation of the JCPOA.
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."1922 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 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.2023
INARA requires the Administration to certify, every 90 days, that all of four 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. These provisions raise the possibility of several courses of action.
President Trump had the option of certifying that all four INARA compliance conditions are met and renewing the waivers of the several secondary sanctions provisions that were issued to implement the JCPOA. Such waiver renewals must be separately transmitted to Congress to comport with the requirements of the sanctions laws that were waived to implement the JCPOA.21 The waivers for those laws that were suspended are due for renewal in mid-January 2018, as discussed in CRS Report RS20871, Iran Sanctions, by [author name scrubbed].
The President had the option of withholding certification of Iranian compliance on any of the grounds stipulated by INARA. His October 13, 2017, speech stated that he would withhold 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 latter claims contradict statements described above from the IAEA, other P5+1 members, and the U.S. government.
Secretary Tillerson wrote in an October 13 letter to Congress that he was "unable to certify" that "continued suspension of [U.S.] sanctions" is "appropriate and proportionate to the specific and verifiable measures taken by Iran with respect to terminating its illicit nuclear program." Trump "has requested that Congress instead work with the Administration to directly address the JCPOA's flaws by amending and strengthening the relevant portions" of INARA, the letter said, adding, "[w]e should work together toward a solution that prevents the emergence of a nuclear-armed Iran and prevents Iran from further developing intercontinental ballistic missiles that undermine regional and international peace and security." U.S. Ambassador Robert Wood stated during an October 23 U.N. meeting that the United States "will work closely with our international partners and the U.S. Congress to explore options for addressing the [JCPOA's] flaws," adding that "[i]n the meantime, the United States will continue to meet its commitments under the JCPOA and will hold Iran strictly accountable for each and every one of its commitments as well."
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 next certification period ends on 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. 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.24 A refusal to certify Iranian compliance under INARA does not automatically cause the reimposition of any Iran sanctions. President Trump did not indicate that he would immediately reimpose sanctions under his own authority as of now. But the decision not to certify Iranian compliance gives Congress the opportunity to act on legislation to reimpose U.S. sanctions under the expedited procedures prescribed in INARA. INARA contains a provision under which sanctions reimposed by the INARA process cannot be waived or otherwise not implemented by the President
If U.S. sanctions are reimposed, Iran might potentially use the justification in Paragraph 26 of the JCPOA to cease performing its nuclear commitments. Iran's reaction might depend on whether other parties to the JCPOA, and companies in those countries, reimpose sanctions or exit the Iran market in response to the reimposition of U.S. sanctions.
As anAn alternative to reimposing those sanctions provisions that have been waived or revoked,sanctions laws or Executive Orders is for the Administration couldto instead restore the "Specially Designated National" (SDN) designation to some or all of the many 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 would resume 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) that close the U.S. financial sector to third-country financial institutionsor 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.
Iran's reaction to redesignation of listed entities would likely depend on how the Administration implemented this option. Redesignation of a few entities that are marginal to Iran's economy might not cause Iran to cease implementing its commitments. However, redesignation of entities that are crucial to Iran's economy, such as the Central Bank of Iran, the Islamic Republic of Iran Shipping Lines (IRISL), Iran Air, or the National Iranian Oil Company (NIOC), could cause Iran to assert that the United States has breached the agreement.
Despite President Trump's withholding of certification of Iranian compliance, Congress might not act to reimpose sanctions under INARA. INARA does not require the Administration to reimpose U.S. sanctions if there is no certification of compliance. President Trump might renew the waivers of U.S. sanctions laws and otherwise decline to reimpose any sanctions that were suspended to implement the JCPOA, whether or not Congress legislates measures to address the JCPOA's weaknesses. The use of this option would therefore keep the United States in the JCPOA.
If sanctions are not reimposed, Iran is likely to continue to implement its commitments under the agreement. Iranian leaders would undoubtedly challenge a withholding of U.S. compliance certification, but Iran likely would continue to implement the agreement as long as sanctions are not reimposed and its economy is, therefore, not damaged by them.

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.)

The possible implications of a U.S. decision to cease implementing the JCPOA by reimposing U.S. sanctions on Iran are varied and extensive, and in many ways dependent on the reactions of Iran and of U.S. allies and partners to that decision. Some possible implications are as follows:
