 美国及其 5 常+1 伙伴在欧盟协调下，与伊朗达成了一项政治谅解，为长期、全面地解决伊朗核问题奠定了基础。一项《联合综合行动计划》如果得到全面实施，将让国际社会相信伊朗不会获得核武器并且其核计划绝对是和平地向前推进的。美国及其伙伴打算在2015 年 6 月 30 日前完成关于《联合综合行动计划》的谈判。
 The United States and its P5+1 partners, coordinated by the EU, have reached a political understanding with Iran that forms the basis for a long-term, comprehensive solution to the Iran nuclear issue. A Joint Comprehensive Plan of Action (JCPOA), if fully implemented, will give the international community confidence that Iran will not obtain a nuclear weapon and that its nuclear program is exclusively peaceful going forward. The United States and its partners aim to conclude talks on the JCPOA by June 30, 2015.
