伊朗违反了2015年核协议。 Iran has breached the 2015 nuclear deal.

自 2015 年与主要大国达成的核协议削弱以来，伊朗推进了其核计划，缩短了其选择研制核武器所需的时间，尽管伊朗否认有任何此类意图。 Iran has advanced its nuclear program since the 2015 nuclear deal with major powers weakened, reducing the time needed to develop a nuclear weapon if it chose to, though Iran denies any such intentions. 该国违反了该协议的所有关键限制，将其浓缩铀库存增加到 5.5 吨，如果进一步浓缩，足以制造两枚核武器。 The country has breached all key restrictions of the deal, increasing its enriched uranium stockpile to 5.5 tonnes, enough to create two nuclear weapons if further enriched. 伊朗目前正在进行纯度高达60%的铀浓缩，且未与国际原子能机构充分合作，因此难以全面监控其核活动。 Iran is currently enriching uranium up to 60% purity and is not fully cooperating with the International Atomic Energy Agency, making it difficult to fully monitor its nuclear activities. 预计伊朗研制出武器化核武器需要数月至一年的时间。 Estimates on the time it would take for Iran to develop a weaponized nuclear weapon range from months to a year.
