Throughout these talks, Iran’s negotiators have been serious. Iran has also defied the expectations of some by meeting its obligations under the Joint Plan of Action, which has allowed time and space for the comprehensive negotiations to proceed. Specifically, Iran has been eliminating its stockpile of higher levels of enriched uranium, limited its enrichment capability by not installing or starting up additional centrifuges, refrained from making further advances at its enrichment facilities and heavy-water reactor, and allowed new and more frequent inspections. In exchange, the European Union and the P5+1 have provided limited financial relief to Iran, even as the architecture of international sanctions and the vast majority of sanctions themselves remained firmly in place.
Now Iran must choose. During the comprehensive negotiations, the world has sought nothing more than for Iran to back up its words with concrete and verifiable actions. We have, over the past several months, proposed a series of reasonable, verifiable and easily achievable measures that would ensure Iran cannot obtain a nuclear weapon and that its program is limited to peaceful purposes. In return, Iran would be granted phased relief from nuclear-related sanctions.
