We have long recognized that the Iranian nuclear program constitutes one of the most serious threats to U.S. national security and our interests in the Middle East. Thanks to the sanctions pressure, and a firm and united position from the P5+1 (China, France, Russia, UK, U.S., and Germany, in coordination with the EU), we have reached an understanding that constitutes the most significant effort to halt the advance of Iran's nuclear program in nearly a decade. As a consequence, the JPA agreed to in Geneva is profoundly in America's national security interest, and makes our regional partners safer and more secure.

The JPA is sequenced, with a 6-month period designed explicitly to block near-term Iranian pathways to a nuclear weapon, while creating space for a long-term comprehensive solution. The goal of that comprehensive solution is to resolve the international community's concerns with Iran's nuclear program. What this initial plan does is help ensure that Iran's nuclear program cannot advance while negotiations towards that solution proceed.

Upon implementation in the coming weeks, this initial step will immediately: halt progress of the Iranian nuclear program; roll it back in key respects; and introduce unprecedented monitoring into Iran's nuclear activities. Taken together, these measures will prevent Iran from enhancing its ability to create a nuclear weapon and increase the confidence in our ability to detect any move towards nuclear break-out or diversion of material towards a covert program.
