Comprehensive Agreement On The Iranian Nuclear Program

The Joint Comprehensive Plan of Action (JCPOA; (, BARJAM)), also known as the Iran nuclear deal or Iran deal, is an agreement to limit the Iranian nuclear program in return for sanctions relief and other provisions. The agreement was finalized in Vienna on 14 July 2015, between Iran and the P5+1 (the five permanent members of the United Nations S.C.—China, France, Russia, the U.K., U.S.—plus Germany) together with the European Union.

Formal negotiations began with the adoption of the Joint Plan of Action, an interim agreement signed between Iran and the P5+1 countries in November 2013. Iran and the P5+1 countries engaged in negotiations for the following 20 months and, in April 2015, agreed on an Iran nuclear deal framework, which later led to JCPOA, along with a Roadmap Agreement between Iran and the International Atomic Energy Agency (IAEA).

Negotiations centered around sanctions relief and restrictions on Iran's nuclear facilities, including the Arak IR-40 reactor, Bushehr Nuclear Power Plant, Gachin Uranium Mine, Fordow Fuel Enrichment Plant, Isfahan Uranium Conversion Plant, Natanz Uranium Enrichment Plant, and the Parchin Military Research complex.

The agreement took effect on 20 January 2016.
It was criticized and opposed in the United States, Israel, Saudi Arabia, and by Iranian principlists.

The United States withdrew from the pact in 2018, imposing sanctions under its maximum pressure campaign. The sanctions applied to all countries and companies doing business with Iran and cut it off from the international financial system, rendering the nuclear deal's economic provisions null.

New talks

Timeline

The agreement included a series of provisions describing actions that Iran would undertake for specified periods of time.

For 13 years, Iran agreed to eliminate its stockpile of medium-enriched uranium, cut its stockpile of low-enriched uranium by 98%, and reduce by about two-thirds the number of its gas centrifuges.

For 15 years, Iran agreed to enrich uranium only up to 3.67% and not to build heavy-water facilities.

For 10 years, uranium enrichment would be limited to a single facility using first-generation centrifuges. Other facilities would be converted to avoid proliferation risks.

IAEA would have regular access to all Iranian nuclear facilities to monitor compliance.

In return for verifiably abiding by those provisions, Iran would receive relief from U.S., European Union, and United Nations S.C. nuclear-related sanctions.

The JCPOA formed part of U.N. Security Council Resolution 2231. The Security Council (S.C.) enacted it on 20 July 2015 and adopted it on 18 October.

It took effect on 16 January 2016 (Adoption Day). JCPOA was to remain in effect for eight years or until receipt by the S.C. of an IAEA report stating that IAEA had reached the Broader Conclusion that all nuclear material in Iran remained in peaceful activities, and terminated ten years from Adoption Day.

On 12 October 2017, U.S. President Donald Trump announced that the U.S. would not make the certification provided for under U.S. domestic law, but stopped short of terminating the deal.

In 2018, IAEA inspectors spent an aggregate of 3,000 calendar days in Iran, installing seals and collecting surveillance camera photos, measurement data, and documents for further analysis. In March 2018, IAEA Director Yukiya Amano said that the organization had verified that Iran was implementing its nuclear-related commitments. On April 30, the U.S. and Israel said that Iran had not disclosed a past covert nuclear weapons program to the IAEA, as required.

On 8 May 2018, Trump announced U.S. withdrawal from JCPOA. On 7 August 2018, the E.U. enacted a blocking statute to defeat U.S. sanctions on countries trading with Iran. In November 2018, U.S. sanctions came back into effect, intended to force Iran to alter its policies, including its support for militant groups in the region and its development of ballistic missiles.

In May 2019, IAEA certified that Iran was abiding by the main terms, though questions were raised about how many advanced centrifuges Iran was allowed to have, which was only loosely specified in the deal.

On 1 July 2019, Iran announced that it had breached the limit set on its stockpile of low-enriched uranium, which the IAEA confirmed.

On 5 January 2020, Iran declared that it would no longer abide by the deal's limitations but would continue to coordinate with IAEA.

Background

Nuclear technology

A fission-based "atomic" nuclear weapon uses a fissile material to cause a nuclear chain reaction. The most commonly used materials are uranium 235 () and plutonium 239 (). Both uranium 233 () and reactor-grade plutonium have also been used. The amount of uranium or plutonium needed depends on the sophistication of the design, with a simple design requiring approximately 15 kg of uranium or 6 kg of plutonium and a sophisticated design requiring as little as 9 kg of uranium or 2 kg of plutonium. Plutonium is almost nonexistent in nature, and natural uranium is about 99.3% uranium 238 () and only 0.7% .

To make a weapon, either uranium must be enriched or plutonium must be produced. Uranium enrichment is required for nuclear power, although not to the same purity. For this reason, uranium enrichment is a dual-use technology required for both civilian and military purposes. Key strategies to prevent proliferation of nuclear arms include limiting the number of operating uranium enrichment plants and controlling the export of nuclear technology and fissile material.

Iranian nuclear activity, 1970–2006

Iranian development of nuclear technology began in the 1970s, when the U.S. Atoms for Peace program began providing assistance. Iran ratified the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) in 1970.

After the 1979 Iranian Revolution, Iran's nuclear program fell into disarray as "much of Iran's nuclear talent fled the country in the wake of the Revolution". The new leader, Ayatollah Ruhollah Khomeini, initially opposed nuclear technology.

In the late 1980s Iran reinstated its nuclear program, with assistance from China (which entered into an agreement with Iran in 1990), Pakistan (which did the same in 1992), and Russia (which did the same in 1992 and 1995), and from the Abdul Qadeer Khan, A.Q. Khan network. Iran began pursuing nuclear capability, including uranium mining and experimenting with uranium enrichment.

In August 2002 the Paris-based Iranian dissident group National Council of Resistance of Iran publicly revealed the existence of two undeclared nuclear facilities, the Arak, Iran, Arak heavy-water production facility and the Natanz enrichment facility. In February 2003, Iranian President Mohammad Khatami acknowledged the existence of the facilities and acknowledged that Iran had undertaken "small-scale enrichment experiments" to produce low-enriched uranium for power plants. IAEA inspectors visited Natanz. In May 2003 Iran allowed IAEA inspectors to visit the Kalaye Electric Company, but not to take samples.

In June 2003, an IAEA report concluded that Iran had failed to meet its obligations under the safeguards agreement. Iran, faced with the prospect of a U.N. UN Security Council, S.C. referral, entered negotiations with France, Germany, and the United Kingdom (the E.U. 3). The U.S. took no part. In October 2003, Iran and the E.U. 3 agreed to the Tehran Declaration. Iran agreed to full IAEA cooperation, to sign the Additional Protocol, and to temporarily suspend uranium enrichment. In September and October 2003 the IAEA inspected several facilities. This was followed by the Paris Agreement in November 2004, in which Iran agreed to temporarily suspend enrichment and conversion activities, including those related to centrifuges, and committed to working with the EU-3 to find a diplomatic solution".

In August 2005, Iranian president of Iran, President 2005 Iranian presidential election, Mahmoud Ahmadinejad accused the Iranian negotiators of treason. Over the following two months, the E.U. 3 agreement fell apart as talks over the Long Term Agreement broke down; the Iranian government "felt that the proposal was heavy on demands, light on incentives, did not incorporate Iran's proposals, and violated the Paris Agreement". Iran notified IAEA that it would resume enrichment at Esfahan.

In February 2006, Iran ended its implementation of the Additional Protocol and resumed enrichment at Natanz, prompting IAEA to refer Iran to the S.C. In April 2006 Ahmadinejad claimed that Iran had explored nuclear technology for power generation, not weapons. In June 2006 the E.U. 3 joined China, Russia, and the U.S., to form the P5+1. That July, the S.C. passed its first United Nations Security Council Resolution 1696, resolution (nr. 1696), demanding Iran stop uranium enrichment and processing. S.C. resolution United Nations Security Council Resolution 1737, 1737 was adopted in December; followed by others. The legal authority for IAEA referral and the S.C. resolutions derived from the IAEA Statute and the United Nations Charter. The resolutions demanded that Iran cease enrichment activities, and imposed sanctions, including bans on the transfer of nuclear and missile technology to the country and freezes on the assets of certain Iranian individuals and entities.

In July 2006, Iran opened the Arak heavy water production plant, which led to another S.C. resolution.

S.C. resolutions, 2007–2013

Four more S.C. resolutions followed: United Nations Security Council Resolution 1747, 1747 (March 2007), United Nations Security Council Resolution 1803, 1803 (March 2008), United Nations Security Council Resolution 1835, 1835 (September 2008), and United Nations Security Council Resolution 1929, 1929 (June 2010). In Resolution 1803 and elsewhere the S.C. acknowledged Iran's rights under Article IV of the NPT, which provides the "inalienable right... to develop research, production and use of nuclear energy for peaceful purposes".Paul K. Kerry

''Financial Times'' (19 February 2007). ElBaradei specifically proposed a "double, simultaneous suspension, a time out" as a confidence-building measure, under which sanctions and enrichment would be suspended.

Kerr

Congressional Research Service (30 July 2015).

In September 2009 U.S. President Barack Obama revealed the existence of an underground enrichment facility in Fordow, near Qom. Israel threatened military action.

Joint Plan of Action (2013)

In March 2013 the U.S. and Iran began talks in Oman, led by William J. Burns (diplomat), William Burns and Jake Sullivan (U.S.) and Ali Asghar Khaji (Iran). In June 2013 Hassan Rouhani was elected president of Iran. In a 2006 negotiation with Europe, Rouhani said that Iran had used the negotiations to dupe the Europeans, saying that during the negotiations, Iran had mastered the conversion of uranium yellowcake at Isfahan. In August 2013, three days after his inauguration, Rouhani called for negotiations with the P5+1."Timeline of Nuclear Diplomacy With Iran"
, Arms Control Association (July 2015).

In September 2013 Obama and Rouhani spoke by telephone, the first high-level contact between U.S. and Iranian leaders since 1979, and Secretary of State John Kerry met with Foreign Minister Mohammad Javad Zarif. Former officials alleged that, in order to advance the deal, the Obama administration shielded Hezbollah from the Central Intelligence Agency and from the Drug Enforcement Administration's Project Cassandra investigation regarding drug smuggling. Attorney General Jeff Sessions ordered an investigation.

On 24 November 2013, after several rounds of negotiations, the interim Joint Plan of Action was signed between Iran and the P5+1. It consisted of a short-term program freeze in exchange for decreased economic sanctions. The IAEA began inspections under this interim agreement. The agreement was formally activated on 20 January 2014. That day, an IAEA report stated that Iran was adhering to the terms of the interim agreement, including stopping enrichment of uranium to 20%, beginning to dilute half of the stockpile of 20% enriched uranium to 3.5%, and halting work on the Arak heavy-water reactor.

A major focus of the negotiations was limitations on the Arak, Iran, Arak IR-40 heavy water reactor and production plant (which was under construction, but never became operational. Iran agreed in the Joint Plan of Action not to commission or fuel the reactor; the Bushehr Nuclear Power Plant; the Gachin Uranium mining, uranium mine; the Fordow Fuel Enrichment Plant; the Isfahan uranium-conversion plant; the Natanz uranium enrichment plant; and the Parchin military research and development complex.

In 2015, the U.S. enacted the Iran Nuclear Agreement Review Act of 2015. Under the Act, once a nuclear agreement was negotiated with Iran, Congress had 60 days in which to pass a resolution of approval, a resolution of disapproval, or do nothing.Jonathan Weisman & Julie Hirschfeld Davis
"Republican Lawmakers Vow Fight to Derail Nuclear Deal"
, ''The New York Times'' (14 July 2005). The Act included time beyond the 60 days for the president to veto a resolution and for Congress to vote on whether to override the veto.Kevin Liptak

Provisions

The Joint Comprehensive Plan of Action (JCPOA) covered 109 pages, including five annexes.Michael R. Gordon & David E. Sanger

, ''The New York Times'' (14 July 2015). The major provisions are:

Nuclear

Stocks

Over 15 years, Iran would reduce its stockpile of low-enriched uranium by 97%, from 10,000 kg to 300 kg, and limit enrichment to 3.67%, sufficient for civilian nuclear power and research, but not for weaponry."Press Availability on Nuclear Deal With Iran"
, U.S. Department of State (14 July 2015). This represented a "major decline" in Iran's nuclear activity. Iran had produced stockpiles near 20% (medium-enriched uranium). Stocks in excess of 300 kg enriched up to 3.67% would be diluted to 0.7% or sold in return for uranium ore, while uranium enriched to between 5% and 20% was to be fabricated into fuel plates for the Nuclear facilities in Iran, Tehran Research Reactor or sold or diluted to 3.67%. P5+1 agreed to facilitate commercial contracts.

After 15 years, all limits on enrichment would be removed, including limits on the type and number of centrifuges, Iran's stocks of enriched uranium, and enrichment sites. According to Belfer, at this point Iran could "expand its nuclear program to create more practical overt and covert nuclear weapons options".

Centrifuges

Iran initially possessed centrifuges sufficient for one nuclear weapon, but not for nuclear power. Over ten years, Iran would secure over two-thirds of its centrifuges in storage, reducing active units to 6,104 centrifuges, with only 5,060 allowed to enrich uranium. Enrichment would be restricted to the Natanz plant. The centrifuges there were limited to IR-1 centrifuges, Iran's oldest and least efficient; Iran would warehouse its advanced IR-2M centrifuges during this period. Non-operating centrifuges would be stored in Natanz and monitored by IAEA, but could be used to replace failed centrifuges. Iran agreed to build no enrichment facilities for 15 years.

Research

Iran could continue research and development work on enrichment only at the Natanz facility and had to respect specific limitations for eight years. The intent was to maintain a one-year breakout interval.

Reactors

With cooperation from the "Working Group" (the P5+1 and possibly other countries), Iran was permitted to modernize the IR-40, Arak heavy water research reactor based on an agreed design. Arak was to be limited to 20 Watt, MWt to support allowed research and production, while minimizing plutonium production and avoiding weapons-grade plutonium. Spent fuel was to be sent out of the country. All heavy water beyond Iran's reactor needs was to be exportable. In exchange, Iran imported 130 tonnes of uranium ore in 2015 and in late 2016 was approved to import 130 tonnes in 2017. For 15 years Iran agreed not to research or engage in spent fuel reprocessing, build additional heavy-water reactors, or accumulate heavy water.

Fordow Fuel Enrichment Plant, Fordow would stop researching and enriching uranium for at least 15 years. The facility was to be converted into a nuclear physics and technology center. For 15 years Fordow would maintain no more than 1,044 IR-1 centrifuges in six cascades in one wing. Two of the six cascades would be transitioned for stable radioisotope production for medical, agricultural, industrial, and scientific use. The other four would remain idle. Iran agreed to keep no fissile material there.

Inspections

A comprehensive inspections regime would monitor and confirm Iranian compliance.

The IAEA was to have multilayeredOren Dorell

, ''USA Today'' (16 July 2015). oversight "over Iran's entire nuclear supply chain, from uranium mills to its procurement of Nuclear technology, nuclear-related technologies".Ishaan Tharoor
"How the nuclear deal can keep Iran from 'cheating,' according to a former U.N. inspector"
, ''The Washington Post'' blogs (15 July 2015). For sites such as Fordow and Natanz, the IAEA was to have 24-hour access to nuclear facilities and to maintain continuous monitoring (including via surveillance equipment).Rebecca Kaplan
"Obama says inspectors get access to 'any' site in Iran. Is it true?"
, CBS News (14 June 2015). The agreement authorized the IAEA to use sophisticated monitoring technology, such as Fiber optics, fiber-optic equipment seals that could send the IAEA information; satellite imagery to detect covert sites; sensors to detect minute nuclear specimens; and tamper- and radiation-resistant cameras.William J. Broad
"Iran Accord's Complexity Shows Impact of Bipartisan Letter"
, ''The New York Times'' (14 July 2015). Other tools included software to gather information and detect anomalies, and datasets on imports. The number of inspectors tripled to 150.

Inspectors could request access, informing Iran of the basis of the request, to verify the absence of prohibited activities and nuclear materials. The inspectors were to come only from countries with which Iran had diplomatic relations. Iran could either allow the inspection or propose alternatives that satisfied the IAEA's concerns. If the inspectors were not satisfied, a 24-day process would ensue. Iran and the IAEA were to have 14 days to reach agreement. For the following week a majority of the commission could require Iran to take specific actions within three more days.Carol Morello & Karen DeYoung

, ''The Washington Post'' (14 July 2015). This allowed the U.S. and its allies to insist on responses that Iran, Russia or China could not veto. After three days of non-compliance, sanctions would be automatically reimposed.

Breakout

These provisions were intended to extend the "breakout time"—the interval during which Iran could prepare enough material for a single nuclear weapon—from two to three months to one year.Obama: Iran Will Face Longer 'Breakout Time,' Though Not Indefinitely
''All Things Considered'', NPR (11 August 2015). See als
"Transcript: President Obama's Full NPR Interview On Iran Nuclear Deal"
, NPR (7 April 2015). Harvard University's Belfer Center for Science and International Affairs and Center for Arms Control and Non-Proliferation"Factsheet: Longevity of Major Iran Nuclear Agreement Provisions"
, Center for Arms Control and Proliferation (14 July 2015). supported these estimates. By contrast, Alan J. Kuperman, coordinator of the Nuclear Proliferation Prevention Project at University of Texas at Austin, disagreed, arguing that the breakout time would be only three months.

After ten years or more, the breakout time would gradually decrease. By the 15th year, U.S. officials said the breakout time would return to the List of Latin phrases (S), ''status quo ante'' of a few months. The Belfer Center report stated: "Some contributors to this report believe that breakout time by year 15 could be comparable to what it is today—a few months—while others believe it could be reduced to a few weeks."

Exemptions

Iran was granted exemptions prior to 16 January 2016. Their reported purpose was to enable sanctions relief and other benefits to start by that date. The exemptions allowed Iran to:

* exceed the 300 kg of 3.5% LEU limit;
* exceed the zero kg of 20% LEU limit;
* keep operating 19 "hot cells" that exceed the size limit;
* maintain control of 50 tonnes of heavy water that exceeded the 130-tonne limit by storing the excess at an Iran-controlled facility in Oman.

Sanctions

Iran had to submit a full report on its nuclear history before it could receive any sanctions relief. At the time of the agreement, Iran was subject to a variety of sanctions imposed by an array of organizations. Once IAEA verified compliance with the nuclear-related measures, U.N. sanctions would terminate. Some E.U. sanctions would terminate and some would suspend. That would allow Iran to recover approximately Iranian frozen assets, $100 billion of its assets frozen in overseas banks. No U.N. or E.U. nuclear-related sanctions or restrictive measures were to be imposed.Jessica Simeone & Anup Kaphle

The U.S. agreed to suspend its nuclear-related United States sanctions, secondary sanctions.Ellie Geranmayeh
"Explainer: The Iran nuclear deal"
European Council on Foreign Relations (17 July 2015) This was not tied to a date or compliance but was expected to occur "roughly in the first half of 2016". Some sanctions would continue: those on conventional weapon sales for five years; those on ballistic missile technologies for eight. But sanctions related to human rights, missiles, and support for terrorism remained in effect. Many U.S. sanctions apply worldwide; E.U. sanctions apply only in Europe.

Snapback

Any of the P5+1 could invoke a "snapback" provision, under which sanctions would be reimposed. Snapback sanctions would not apply retroactively to previously allowed contracts.

Dispute resolution

Any party could refer allegations of non-compliance to the Joint Commission monitoring body. Complaints by a non-Iran party that were not resolved to the complainant's satisfaction within 35 days would allow the complainant to cease performing its commitments, notify the S.C., or both. The S.C. would then have 30 days to adopt a resolution to continue the sanctions relief. Absent such a resolution, nuclear-related U.N. sanctions would automatically be reimposed. Iran said it would then cease performing its nuclear obligations. This would allow any Permanent members of the United Nations Security Council, permanent S.C. member (U.S., United Kingdom, China, Russia or France) to veto sanctions relief.

This procedure implied that the U.S., U.K., or France could reinstitute sanctions if it concluded that Iran was non-compliant, though since that might cause Iran to withdraw from the agreement, they might be reluctant to do so.

Expiration

After 15 years, many provisions of the JCPOA would expire, including most enrichment provisions.

International reaction

The JCPOA received a mixed international reaction. Many countries expressed hope that it could achieve its goals,"Iran deal 'sufficiently robust' for 10 years, says France's foreign minister Laurent Fabius"
, ''The Economic Times'', Reuters (14 July 2015). while Iranian adversaries in the Middle East, including Israel and Saudi Arabia, and some U.S. lawmakers saw it as defective and appeasing Iran.Adam Wollner

Unique elements

JCPOA was the first of its kind in the annals of non-proliferation. The 159-page JCPOA document and its five appendices is the longest text of a multinational agreement since World War II, according to BBC Persian.

It was the first time that the S.C. had recognized a developing country's nuclear enrichment program and backed a multinational agreement within the framework of a resolution (United Nations Security Council Resolution 2231, 2231). For the first time in U.N. history, a country—Iran—was able to rid itself of 6 U.N. resolutions—United Nations Security Council Resolution 1696, 1696, United Nations Security Council Resolution 1737, 1737, United Nations Security Council Resolution 1747, 1747, United Nations Security Council Resolution 1803, 1803, United Nations Security Council Resolution 1835, 1835, United Nations Security Council Resolution 1929, 1929—without abiding by them for a single day. Sanctions against Iran were lifted for the first time.

Iran was the first country subject to Chapter VII of the United Nations Charter that ended its case by diplomacy. All other cases ended by regime change, war, or acquiescence.

Gary Sick said that during the history of the Nuclear Non-Proliferation Treaty (NPT), no country other than Iran had ever voluntarily agreed to such restrictions.

During the final negotiations, Kerry stayed in Vienna for 17 days, the longest interval a Cabinet official had devoted to a single international negotiation in more than four decades. Zarif broke the record for an List of Ministers of Foreign Affairs of Iran, Iranian Foreign Minister staying far from home with an 18-day stay in Vienna, and set the record of 106 days of negotiations over 687 days, more than any other List of Iranian nuclear negotiators, chief nuclear negotiator in 12 years. The negotiations became the longest continuous negotiations with the presence of all five foreign ministers of the permanent members of the United Nations Security Council, permanent S.C. members.

The negotiations included "rare events" in Iran–United States relations, Iran–U.S. relations over their entire history. Kerry and Zarif met on 18 different dates—sometimes more than once per day—and in 11 different cities. On 27 April 2015, Kerry visited the official residence of the Permanent Representative of Iran to the United Nations to meet his counterpart. The encounter was the first since the Iran hostage crisis. On the sidelines of the General debate of the seventieth session of the United Nations General Assembly, 70th session of the United Nations General Assembly, President Obama shook hands with Zarif, the first such greeting in history. The event was unique in the form of diplomatic ranks, as a head of state shook hands with a Minister (government), minister. Obama said, "Too much effort has been put into the JCPOA and we all should be diligent to implement it."

History

Negotiations (2014–2015)

JCPOA was the culmination of a 20-month negotiation.

The parties extended their talks, first to 24 November 2014 and then to 1 July 2015.

A Iran nuclear deal framework, framework was agreed on 2 April 2015 at Lausanne. Under this framework Iran tentatively agreed to accept restrictions, all of which would last for a decade or longer, and to submit to increased Nuclear program of Iran#International Atomic Energy Agency reports, 2007–2015, inspections. Negotiations continued, ending in Vienna at the Palais Coburg. On 14 July 2015, all parties agreed.

The agreement reflects the impact of a June 2015 public letter by a bipartisan group of U.S. diplomats, experts, and others."Public Statement on U.S. Policy Toward the Iran Nuclear Negotiations Endorsed by a Bipartisan Group of American Diplomats, Legislators, Policymakers, and Experts"
, Washington Institute for Near East Policy (24 June 2015). The letter outlined concerns about various provisions and called for strengthening the agreement. After the agreement was reached, one of the negotiators, Robert Einhorn, a former U.S. Department of State official, said: "Analysts will be pleasantly surprised. The more things are agreed to, the less opportunity there is for implementation difficulties later on."

An analysis by the Carnegie Endowment for International Peace claimed that the final agreement was based upon (and buttressed) "the rules-based nonproliferation regime created by the Nuclear Non-Proliferation Treaty (NPT) and including especially the IAEA safeguards system".

Participants

and Majid Takht-Ravanchi, Mr. Majid [Takht-Ravanchi]."In November 2015, U.S. State Department Assistant Secretary for Legislative Affairs Julia Frifield said: "The JCPOA is not a treaty or an executive agreement, and is not a signed document. The JCPOA reflects political commitments between Iran, the P5+1, and the EU."

(17 July 2015).

Speaking immediately after the vote, Power told the S.C. that sanctions relief would start only when Iran "verifiably" met its obligations. She also called upon Iran "to immediately release all unjustly detained Americans", specifically naming Amir Hekmati, Saeed Abedini, and Jason Rezaian, who were detained at the time, and Robert A. Levinson, who had been missing in the country. Hekmati, Abedini, and Rezaian were released in a January 2016 prisoner exchange, which Kerry said the nuclear agreement had accelerated.

European Union

On the same day that the S.C. approved its resolution, the E.U. formally approved the JCPOA via a vote of the E.U. Foreign Affairs Council (the group of E.U. foreign ministers) meeting in Brussels. This set into motion the lifting of certain E.U. sanctions, including those prohibiting the purchase of Iranian oil.Robin Emmott & Francesco Guarascio
"Europe backs Iran nuclear deal in signal to U.S. Congress"
, Reuters (20 July 2015). The E.U. continued its sanctions relating to human rights and Export control, prohibiting the export of ballistic missile technology.

Review period in the U.S. Congress

The agreement's legal status in the U.S. was disputed. Under U.S. law, the JCPOA is a non-binding political commitment. According to the State Department, it specifically is not an executive agreement nor a Treaty Clause, treaty (as defined in U.S. law). In contrast to treaties, which require two-thirds of the Senate to consent to ratification, executive commitments require no Congressional approval and are not legally binding as a matter of domestic law, but in some cases they may be considered such and bind the U.S. under international law.Amber Phillips
"Can Congress stop the Iran deal?"
, ''The Washington Post'' (1 July 2015).

On 19 July 2015, the State Department officially transmitted the JCPOA to Congress.
, United States Department of State (19 June 2015). The referral included the Unclassified Verification Assessment Report on the JCPOA and the United States Intelligence Community, Intelligence Community's Classified Annex to the Verification Assessment Report. The 60-day review period began on 20 July and ended on 17 September. A resolution of disapproval was brought to the Senate floor but failed. A resolution of approval was brought to the House floor, and also failed. As a result, the agreement went into effect after the congressional review period.

Senate Majority Leader Mitch McConnell promised that Republicans would discuss the agreement respectfully in September. Democrat Senate Minority Leader Chuck Schumer distinguished the nuclear and non-nuclear aspects. His conclusion was: "when it comes to the nuclear aspects of the agreement within ten years, we might be slightly better off with it.

The anti-agreement coalition included former president Mahmoud Ahmadinejad, former head of AEOI Fereydoon Abbasi, ex-nuclear negotiator Saeed Jalili, and various conservative clerics and IRGC commanders. This group claimed that Iranian negotiators caved on many key issues and were outmaneuvered.

The Majlis special commission for examining the JCPOA, Majlis commission for examining the JCPOA invited Ali Shamkhani, as well as members of a former List of Iranian nuclear negotiators, nuclear negotiation team including Ali Bagheri and Abbasi, to a hearing. During the session, ex-chief negotiator Saeed Jalili said that "approximately 100 absolute rights" of Iran had been conceded and that the deal turned Iran's right to adopt nuclear technology under the NPT into mere permission. He claimed that the deal violated the terms Khamenei set. Commission members Masoud Pezeshkian and Abbas Ali Mansouri Arani criticized Jalili's testimony. In another session, negotiators Abbas Araqchi and Majid Takht-Ravanchi defended the deal.

On 13 October the Iranian Parliament approved the JCPOA supplemented by text unilaterally added by Iran and not agreed to by the P5+1, with 161 votes in favor, 59 against, and 13 abstentions.

Adoption Day

On 18 October 2015 E.U. High Representative Mogherini and Iranian Foreign Minister Zarif jointly announced "Adoption Day".

On 20 September 2015, Director-General Yukiya Amano of the IAEA went to the Parchin missile production facility, along with Director of Safeguards Tero Varjoranta, to obtain clarifications on the site's nuclear activities. The next day, Amano professed satisfaction with the samples submitted by the Iranians to the IAEA. IAEA experts were not physically present during the sampling, but Amano said the procedure met "strict agency criteria". In June 2016, IAEA investigators reported that they had reported traces of uranium found at the Parchin facility in December 2015.

Implementation Day

After the IAEA certified that Iran had met the relevant JCPOA requirements, all nuclear sanctions were lifted by the UN, the E.U. and the U.S. on 16 January 2016, "Implementation Day".

That day Washington imposed sanctions on 11 companies and individuals for supplying Iran's ballistic missile program. According to Kerry, $1.7 billion in debt with interest was to be paid to Tehran. But some Iranian financial institutions, including Ansar Bank, Bank Saderat, Bank Saderat PLC, and Mehr Bank, remained on the SDN List and U.S. sanctions with respect to Iran, including existing terrorism, human rights and ballistic missiles-related sanctions, remained in effect.

Status in U.S. law

In a letter sent to then Representative Mike Pompeo, the State Department said that the JCPOA "is not a treaty or an executive agreement, and is not a signed document".

According to the Congressional Research Service, different definitions of "treaty" are used in international and U.S. law. According to the Vienna Convention on the Law of Treaties, "The term 'treaty' has a broader meaning under international law than under domestic law. Under international law, 'treaty' refers to any binding international agreement. Under domestic U.S. law, 'treaty' signifies only those binding international agreements that have received the advice and consent of the United States Senate, Senate."

Deterrence

Michael Eisenstadt, Director of the Military and Security Studies Program at the Washington Institute for Near East Policy, wrote that deterrence must remain the "core imperative" for U.S. policy. Einhorn wrote that maintaining a credible deterrent was essential.

Obama stated that the U.S. would continue its policy of deterring any Iranian efforts to develop nuclear weapons, including via military force. Flexibility meant that Obama rejected specifying "the penalties for smaller violations of the accord" in advance.

Dennis Ross and David Petraeus claimed that deterrence including military force was essential to preventing Iran from nuclear weapons and called on Obama to clearly state that policy.

Khamenei claimed that his Khamenei's fatwa against nuclear weapons, fatwa and not JCPOA was the reason Iran would not acquire nuclear weapons.

Trump administration (2017)

The U.S. certified in April 2017 and in July 2017 that Iran was complying with the deal.

On 13 October 2017 President Trump announced that he would not make the certification required under the Iran Nuclear Agreement Review Act of 2015, ''Iran Nuclear Agreement Review Act'', accusing Iran of violating the spirit of the deal and calling on the U.S. Congress and international partners to "address the deal's many serious flaws".

Trump left Congress to decide whether to reimpose sanctions. Trump's aides sought to enact rules indicating how the U.S. could reimpose sanctions. Trump listed three items that could provoke the U.S. to reject deal: intercontinental ballistic missile development, Iranian refusal to extend the constraint period, and evidence that Iran had reduced the time needed to manufacture a bomb to fewer than 12 months.

Rouhani, Theresa May, Emmanuel Macron, Angela Merkel, and European Union foreign policy chief Federica Mogherini said the agreement was working well and that no one country could break it, reconfirming support for the deal. Russian foreign minister Sergey Lavrov confirmed that Iran was in compliance.

U.S. withdrawal (May 2018)

On 8 May 2018 the U.S. officially withdrew after Trump signed a Presidential Memorandum ordering sanctions reinstatement, opting instead to seek a comprehensive and lasting solution working allies. IAEA continued to certify Iranian compliance. Other signatories said they would comply with the deal even absent the U.S.

Consequences of U.S. withdrawal

The U.S. adopted a policy of "maximum pressure", led by global sanctions.

The Iranian rial fell by some 20%, from 35,000 to the dollar to 42,000 in 2021. International banks that traded with Iran paid heavy fines. The American flag was set on fire in Iran's Parliament. According to Israel Defense Forces sources, IRGC Quds Forces based in Syria launched rockets at Israeli military targets the next evening, the first time Iran had directly targeted Israel. All major European companies abandoned doing business with Iran out of fear of U.S. punishment.

Khamenei's conditions

Khamenei presented seven conditions for Europe to sustain JCPOA. Among them was that European powers must take steps to preserve business relations with Iranian banks and purchase Iranian oil. He rejected holding discussions about Iran's ballistic missile program and regional activities.

Defection of Iran (2019)

One year after the U.S. withdrawal, Iran took countermeasures. Iran halted its required sales of excess enriched uranium and heavy water to other countries. Rouhani said that Iran would resume enrichment beyond 3.67% if other parties could not let Iran benefit from JCPOA's economic provisions.

In May 2019, IAEA certified that Iran was abiding by the deal's main terms, but raised questions about the limits on advanced centrifuges.

On 8 May, Iran announced it would suspend implementation of parts of JCPOA, threatening further action in 60 days absent exemption from U.S. sanctions.

On 7 July, Iran announced that it had started to increase uranium enrichment beyond the agreed 3.67% limit. IAEA said its inspectors would verify Iran's actions. Zarif sent a letter to Mogherini notifying her about Iran's noncompliance.

On 4 November, Iran doubled the number of advanced centrifuges it operated. It began enriching uranium to 4.5%. On 5 November 2019, Iranian nuclear chief Ali Akbar Salehi announced that Iran would enrich uranium to 5% at Fordow, adding that it already had the capability to enrich uranium to 20%.

Diplomatic conflict (2020)

In 2020, Trump and Pompeo asserted that the U.S. remained a "participant" in the agreement, despite having formally withdrawn, in an effort to persuade the S.C. to reimpose pre-agreement sanctions on Iran for its breaches.

Reentry negotiations

2021

New U.S. President Joe Biden stated his intention to reinstate the deal. Israeli Prime Minister Naftali Bennett advised against this, saying that stopping Iran's aggression and preventing Iran from building nuclear weapons should be the priority.

In April, talks between the original parties started in Vienna. Biden put the meetings on hold in June. Enrique Mora, E.U. coordinator for reviving negotiations with Iran, attended President Ebrahim Raisi's inauguration. Iran sought E.U. assurances that the U.S. withdrawal would not repeat. On 14 October, Iran and the E.U. agreed to further negotiations. Iranian deputy foreign minister Ali Bagheri reiterated Mora's statement that "the E.U. was ready to collaborate with Iran and the other parties".

A joint statement by French, German, U.K., and U.S. leaders on 30 October welcomed Biden's interest in reestablishing JCPOA. Talks resumed on 29 November, with representatives from Iran, China, France, Germany, Russia, and the U.K.

Bagheri presented Iran's draft. Western negotiators rejected it. Iranian negotiators insisted that the U.S. lift all sanctions before Iran would scale back its nuclear program. On 9 December, negotiations continued, with Russia and China pushing Iran to revise its stance.

2022

On 20 February, 250 members of the 290-member Iranian parliament, which had been controlled by hardliners since 2020, issued a statement urging Raisi to comply with their requirements for reestablishing JCPOA.

The U.S. engaged in indirect talks with Iran, mediated by China, Russia and E.U. JCPOA revival became a priority for the Biden administration when the Russian invasion of Ukraine spiked global energy prices. JCPOA would add about a million barrels/day of Iranian oil to the international market, which would lower crude oil prices.

Throughout the year, leaders on both sides made statements assessing the state of talks. Points of contention included:

* the IAEA investigation about undeclared materials from three nuclear sites;
* the presence of IRGC on the list of terrorist organizations;
* Russian demands to explicitly protect its economic relations with Iran (eventually Russia received U.S. guarantees to protect its trade with Iran from International sanctions against Iran, international sanctions);
* additional sanctions relief.

By May, talks had stalled. On 7 May, Mora visited Iran to restart them.

In June, Tehran said it was removing 27 U.N. surveillance cameras.

On 16 June, the Biden administration announced sanctions against Iran's petrochemical industry. On 6 July, the U.S. initiated legal proceedings against entities based in Singapore, Vietnam, and the United Arab Emirates for evading sanctions.

In July, indirect talks between the U.S. and Iran failed.

In August European negotiators presented a "final" text, after another round. The draft did not include removal of the IRGC's terrorism designation.

In September, Iran increased its oil exports to China, circumventing sanctions.

A delegation visited Tehran on 18 December to discuss the nuclear material discovered at three sites. Earlier Iran reported it had enriched uranium to its highest level of 60%, one step away from weapons grade.

On 20 December, a meeting was held in Amman, Jordan.

The IAEA censured Iran twice in 2022 for failing to cooperate.

2023

An IAEA report on the Fordow Fuel Enrichment Plant found that two cascades of IR-6 centrifuges were configured in a way "substantially different" from what Iran had previously declared. Iran claimed the difference was due to a human error. On 31 January, the United States Department of State, U.S. State Department authorized a sanctions waiver, which allowed Russia to develop the enrichment site, a move that some criticized because it allowed Iran to develop its nuclear program of Iran, nuclear program with Rosatom, Russian-state controlled firms.

On 4 March, Grossi met with Raisi and other top Iranian officials. Earlier, IAEA had detected uranium particles enriched up to 83.7% at Fordo. In the meantime, Iran gave assurances that it would reinstall monitoring equipment at sensitive locations.

In early June, European powers resumed internal talks. Preliminary negotiations with France, Germany, the U.K., and Ali Bagheri, Ali Bagheri Kani again took place in Oslo. A U.S. State Department official acknowledged that direct connections had been under way, the first since 2018. Both sides had released prisoners accused of espionage and terrorism.

On 18 June, indirect talks between Iran and the U.S. began in Oman after the U.S. allowed the release of blocked Iraqi payments to Iran. On 4 July, Iran–Iraq relations, Iran-Iraq Joint Chamber of Commerce chairman Yahya Ale Eshaq confirmed the release of $10 billion, to be used for unsanctioned goods. This allowed Iran to double its trade with Iraq. As a consequence, IAEA imposed no additional punitive measures on Iran, as European allies saw no benefit. Israel said it opposed "mini-agreements" with Iran, as well as the original agreement.

In late August, after months of negotiations, first in Oman and then with Qatari officials in New York, agreements between the U.S. and Iran led to a gradual easing of sanctions on Iranian oil sales, particularly for eastern markets such as China. Iranian oil sales reached their highest since 2018, allowing prices to drop below $85 a barrel. Skeptical analysts claimed this was simply to keep U.S. gasoline prices in check for the 2024 election. The U.S. State Department insisted on continued sanctions enforcement, while some reports indicated that Iran was slowing its uranium enrichment. Iranian oil production reached 3 million barrels per day in July, with a further increase to at least 3.4 million barrels in August.

In late August, IAEA confirmed that Iran had slowed its program to enrich uranium to 60%. Concurrently, the sale of Iranian crude increased. Some oil sanctions were lifted.

In the first week of September, the U.S. State Department officially released $6 billion in frozen assets and finalized an exchange of five prisoners each. The funds could be used only for unsanctioned goods.

A September IAEA report confirmed an enrichment slowdown, but claimed that no reporting progress had been made and that the camera equipment at the enrichment site remained inaccessible.

In mid-September, the IAEA/Iran relationship further deteriorated when Iran rejected IAEA nuclear inspectors. This was formally permitted by Iran's safeguards agreement.

On 18 September, Raisi spoke at the United Nations General Assembly, U.N. General Assembly and said that Iran would never give up its right to peaceful nuclear energy. He urged Western powers to return to the nuclear deal. Israel left the assembly hall in protest.

In October, Qatar and the U.S. put Iran's access to blocked funds on hold due to the Gaza war, although Iran denied any involvement in the attack.

Additional sanctions were imposed on the Iranian aviation sector due to its involvement with exports of missile components to Russia. Iran denied any deliveries. An IAEA report confirmed the expansion of Iran's enrichment program. Fordow was routinely enriching uranium to 60%. The report said that Iran informed the agency that eight clusters of advanced IR-6 centrifuges had been installed at the site but not brought online. The larger site at Natanz added 15 cascades, allowing an enrichment purity of 5%. IAEA board resolutions required Iran to cooperate with its investigations into uranium traces and called for inspectors to enter nuclear sites.

AEOI spokesman Behrouz Kamalvandi met with representatives of Russia's Joint Institute for Nuclear Research to exchange technical details.

On November 13, IAEA director Rafael Grossi visited Tehran where he was welcomed by Behrouz Kamalvandi, spokesman for the Atomic Energy Organization of Iran (AEOI). Grossi, holding talks with Foreign Minister Abbas Araghchi and AEOI Chief Mohammad Eslami, had earlier said the JCPOA was an "empty shell" but that IAEA inspectors had no evidence that Iran was building a nuclear bomb. During the COP29 climate summit in Baku, he warned that "the international situation is becoming increasingly tense"."IAEA chief on Tehran visit for talks with Iranian officials"
