Indeed, the duration the agreement will be of vital importance. The West wants it to be implemented for as long as possible, while Iran would prefer a very short timeframe within which to achieve its central objectives: a comprehensive and lasting repeal of international sanctions and recognition as an NPT non-military nuclear power.
事实上，协议的持续时间在这里至关重要。西方希望持续的时间越长越好，而伊朗则希望在短时间内达到其全面永久废除国际制裁和跻身不扩散核武器条约非军用有核国家的核心目标。
