The P5+1 (the United States, United Kingdom, Germany, France, Russia, and China, facilitated by the European Union) has been engaged in serious and substantive negotiations with Iran with the goal of reaching a verifiable diplomatic resolution that would prevent Iran from obtaining a nuclear weapon. 

President Obama has been clear that achieving a peaceful resolution that prevents Iran from obtaining a nuclear weapon is in America’s national security interest.  Today, the P5+1 and Iran reached a set of initial understandings that halts the progress of Iran's nuclear program and rolls it back in key respects.  These are the first meaningful limits that Iran has accepted on its nuclear program in close to a decade.  The initial, six month step includes significant limits on Iran's nuclear program and begins to address our most urgent concerns including Iran’s enrichment capabilities; its existing stockpiles of enriched uranium; the number and capabilities of its centrifuges; and its ability to produce weapons-grade plutonium using the Arak reactor.  The concessions Iran has committed to make as part of this first step will also provide us with increased transparency and intrusive monitoring of its nuclear program.  In the past, the concern has been expressed that Iran will use negotiations to buy time to advance their program.  Taken together, these first step measures will help prevent Iran from using the cover of negotiations to continue advancing its nuclear program as we seek to negotiate a long-term, comprehensive solution that addresses all of the international community's concerns. 

In return, as part of this initial step, the P5+1 will provide limited, temporary, targeted, and reversible relief to Iran.  This relief is structured so that the overwhelming majority of the sanctions regime, including the key oil, banking, and financial sanctions architecture, remains in place.  The P5+1 will continue to enforce these sanctions vigorously.  If Iran fails to meet its commitments, we will revoke the limited relief and impose additional sanctions on Iran. 

The P5+1 and Iran also discussed the general parameters of a comprehensive solution that would constrain Iran's nuclear program over the long term, provide verifiable assurances to the international community that Iran’s nuclear activities will be exclusively peaceful, and ensure that any attempt by Iran to pursue a nuclear weapon would be promptly detected.  The set of understandings also includes an acknowledgment by Iran that it must address all United Nations Security Council resolutions – which Iran has long claimed are illegal – as well as past and present issues with Iran’s nuclear program that have been identified by the International Atomic Energy Agency (IAEA).  This would include resolution of questions concerning the possible military dimension of Iran’s nuclear program, including Iran’s activities at Parchin.  As part of a comprehensive solution, Iran must also come into full compliance with its obligations under the Non-Proliferation Treaty (NPT) and its obligations to the IAEA.  With respect to the comprehensive solution, nothing is agreed until everything is agreed.  Put simply, this first step expires in six months, and does not represent an acceptable end state to the United States or our P5+1 partners.

Halting the Progress of Iran’s Program and Rolling Back Key Elements 

Iran has committed to halt enrichment above 5%:

Halt all enrichment above 5% and dismantle the technical connections required to enrich above 5%.

Iran has committed to neutralize its stockpile of near-20% uranium:

Dilute below 5% or convert to a form not suitable for further enrichment its entire stockpile of near-20% enriched uranium before the end of the initial phase.

Iran has committed to halt progress on its enrichment capacity:

Not install additional centrifuges of any type.

Not install or use any next-generation centrifuges to enrich uranium.

Leave inoperable roughly half of installed centrifuges at Natanz and three-quarters of installed centrifuges at Fordow, so they cannot be used to enrich uranium.

Limit its centrifuge production to those needed to replace damaged machines, so Iran cannot use the six months to stockpile centrifuges.

Not construct additional enrichment facilities.
