US Secretary of State John Kerry, EU High Representative Catherine Ashton, and the other parties to the talks – all supported by able teams of diplomats – hammered out the deal’s details over months, staying at the table, compromising, holding firm, and managing the expectations of multiple players (including the press). The Obama administration committed itself to global leadership through civilian rather than military power.
对伊过渡协议的最终赢家是外交进程本身。美国国务卿克里、欧盟高级代表阿什顿（Catherine Ashton）和其他谈判各方——都是能力卓著的外交官团队——花几个月的时间才敲定了协议的细节、让协议来到谈判桌、做出让步、掌控局面，并协调多方（包括媒体）的期望。奥巴马政府本身也致力于通过民事而非军事实力充当全球领导。这就是伊朗核谈判的意义。
