The net result is that the accord should lengthen the period it would take Iran to produce one or more nuclear weapons from several months to as much as a year, making it more likely that such an effort would be discovered in time. The prospect that the JCPOA could keep Iran without nuclear weapons for 15 years is its main attraction.
净结果是，该协议应该能够将伊朗制造一件或多件核武器的时间从几个月延长到一年，增加了这一行为被发现的可能。JCPOA可以在15年内让伊朗无法拥有核武器，这是其最吸引人的地方。光靠制裁无法实现这一点，而动用武力会带来风险极高的不确定性结果。
