The UN Security Council deputized its five permanent members, the United States, France, Britain, Russia and China, plus Germany to negotiate with Iran on measures to guarantee that its nuclear program is purely peaceful as Iran says it is. Iran has violated past agreements on the nuclear program and pursued secret military nuclear research. So the international community wants strict, verifiable controls. Secretary Kerry described the situation this way: It is vital to make certain that Iran is not going to develop a nuclear weapon and their program is peaceful. ___________________ 联合国安理会委派美、法、英、俄、中五个常任理事国,同德国与伊朗就如何采取措施以保证伊方核项目如其所言,出于纯粹的和平目的进行和谈. 伊朗曾违反过去所签署的核项目协议,秘密开展对军事核项目的研究.因此国际社会要求对其进行严格且可核查的管控.国务卿克里描述当下形势如下: 确保伊朗放弃研究核武器,并保证其核项目的和平安全是至关重要的. ____________________
