Negotiations leading to the Joint Comprehensive Plan of Action

[21] U.S. Secretary of State John Kerry and other Western foreign ministers arrived at Vienna to break a deadlock in the nuclear talks with Iran,[22] but their joint efforts failed to advance the negotiations.

The Republican chairman of the United States House Committee on Foreign Affairs Ed Royce said he hoped "the administration will finally engage in robust discussions with Congress about preparing additional sanctions against Iran".

[35] Russian Deputy Foreign Minister Sergei Ryabkov pointed that the issues of Iran's enrichment programme, the schedule for sanction lifting and the future of the reactor in Arak were not settled and the subjects of inspection and transparency, duration of the agreement and some others were not completely agreed yet.

"We are negotiating a binding document, but under a generally recognized doctrine international political liabilities are equated with legal," he said and admitted that some resolutions of the Security Council on Iran will need to be adjusted.

He stressed that while 1 July was the new deadline, the expectation was that broad agreement would be in place by 1 March 2015, that expert level talks would resume in December 2014 and that Iran would receive about $700 million per month in frozen assets.

To clarify past and present issues regarding Iran's nuclear program, the International Atomic Energy Agency will be permitted the use of modern technologies and will have announced access through agreed procedures.

[75] Gary Samore, former White House coordinator for arms control and WMD, participating in a panel, said: "Any deal will have to be struck between Washington and Tehran and then ratified by the P5+1 and ultimately the UN Security Council".

"[89] After the talks, U.S. Secretary of State John Kerry flew to Riyadh, where he was to meet Saudi Arabia's King Salman and the foreign ministers of the members of the Gulf Cooperation Council separately.

"[78] On 15 October 2014 Iranian Foreign Minister Mohammad Zarif, EU High Representative Catherine Ashton and Secretary of State John Kerry have met again, this time in Vienna.

[citation needed] In May 2014 Robert J. Einhorn, former Special Advisor on Non-Proliferation and Arms Control at the U.S. Department of State, claimed that if Iran was to continue to insist on what he considered to be a huge number of centrifuges, then there would be no agreement, since this enrichment capacity would bring the breakout time down to weeks or days.

[115] Under Secretary of State Wendy Sherman, testifying before the Senate Committee on Foreign Relations, said that a good deal will be one that cuts off Iran's uranium, plutonium and covert pathways to obtain nuclear weapons.

[116] President Barack Obama, while addressing the House of Representatives and Senate, emphasized that "these negotiations do not rely on trust; any long-term deal we agree to must be based on verifiable action that convinces us and the international community that Iran is not building a nuclear bomb.

[120] Gregory S. Jones, a senior researcher and a defense policy analyst, claimed that if the heavy-water-production plant at Arak were not dismantled, Iran would be granted a "plutonium option" for acquiring nuclear weapons in addition to the centrifuge enrichment program.

Graham Allison, former United States Assistant Secretary of Defense, and Oren Setter, a research fellow at Belfer Center, compared this approach with Maginot's fixation on a single threat "that led to fatal neglect of alternatives".

"[135] According to the recommendations the agreement with Iran should include a requirement to cooperate with the IAEA inspectors in compliance with the UN Security Council resolutions, transparency for centrifuges, mines and mills for uranium ore and yellowcake, monitoring of nuclear-related procurement, an obligation to ratify and implement the Additional Protocol[136] and to provide the IAEA enhanced powers beyond the Protocol, adhering to the modified Code 3.1,[137][138] monitoring of nuclear research and development (R&D), defining certain activities as breaches of the agreement that could provide basis for timely intervention.

[145][146][147] To implement these and other verification steps, Iran committed to "provide increased and unprecedented transparency into its nuclear program, including through more frequent and intrusive inspections as well as expanded provision of information to the IAEA.

[151] Yukiya Amano, Director General of the IAEA, made a one-day visit to Tehran on 17 August and held talks with President of Iran Hassan Rouhani and other senior officials.

[157] While testifying before the United States House Foreign Affairs Subcommittee on the Middle East and North Africa, Institute for Science and International Security president David Albright commented on Iran's reaction to this report: "the Iranian government continues to dissemble and stonewall the inspectors and remains committed to severely weakening IAEA safeguards and verification in general.

[172] In his testimony before the United States House Committee on Armed Services, Managing Director of the Washington Institute for Near East Policy Michael Singh argued "that Iran should be required to cease elements of its ballistic-missile and space-launch programs as part of a nuclear accord."

According to the U.S. Department of State, any compliance issues wouldn't be discussed by the Joint Commission but would first be dealt with "at the expert level, and then come up to the political directors and up to foreign ministers if needed."

[183] A month later, The New York Times reported that according to a statement by Yukiya Amano, the IAEA Director General, Iran had stopped answering the Agency's questions about suspected past weaponization issues.

"[185] On 16 June 2015 U.S. Secretary John Kerry told reporters that the possible military dimensions problem was a little distorted, since the U.S. was "not fixated on Iran specifically accounting for what they did" and the U.S. had "absolute knowledge" with respect to this issue.

[187] At an August 2005 meeting of the International Atomic Energy Agency (IAEA) in Vienna, the Iranian Government asserted that Ali Khamenei has issued a fatwa declaring that the production, stockpiling and use of nuclear weapons is forbidden under Islam.

Prominent opponents include Israeli Prime Minister Benjamin Netanyahu, former Secretaries of State Henry Kissinger and George P. Shultz, and Democratic Senator Bob Menendez.

[210] Some analysts argue that "Iranian actions, including the evidence of work on weaponization, the development of long-range ballistic missiles, and the placement of the program within the IRGC" indicate that Iran's arsenal is not virtual.

[211] According to policy documents published by the Obama administration, it believes in the efficacy of traditional Cold War deterrence as the remedy to the challenge of states acquiring nuclear weapons.

"[218] Two weeks after the Geneva interim deal was achieved, President Barack Obama disclosed in an interview that while taking office, he decided to "reach out to Iran" and open up a diplomatic channel.

[223] On the basis of international inspectors' reports, The New York Times estimated on 1 June 2015 that Iran's stockpile of nuclear fuel increased by about 20 percent during the last 18 months of negotiations, "partially undercutting the Obama administration's contention that the Iranian program had been 'frozen'".

U.S. President Barack Obama paid a visit to Riyadh in March 2014 and assured King Abdullah that he is determined to stop Iran from getting a nuclear weapon and that the United States would not accept a bad deal.

[232][233][234] At 2015 during Iran nuclear deal in Vienna, the reported remarks from Zarif to EU foreign policy chief Federica Mogherini have since trended on Twitter under the hash tag «#NeverThreatenAnIranian».
