Even without violating the accord, Iran can position itself to break out of nuclear constraints when the agreement’s critical provisions expire. At that point, there will be little to hold it back except the Nuclear Nonproliferation Treaty, a voluntary agreement that does not include penalties for non-compliance.
有一个更大的问题，所受到的关注要小得多：如果伊朗确实遵守了协议会发生什么。即使不违反协议，伊朗也可以在协议的关键条款过期后打破核约束。到那时，除了核不扩散条约以外就再也没有可以凭借的约束，而核不扩散条约是一个自愿协议，没有规定对不遵守的情况施加怎样的惩罚。
