But now, at the plan’s halfway point, there has been little concrete progress, with last month’s negotiations producing no headway on two key issues being discussed: the acceptable level for uranium enrichment in Iran and the future of the heavy-water reactor at Arak. The sharp contrast between this lack of achievement and Iran’s recent declarations about reaching a final deal by July raises important questions about Iran’s strategy and goals – questions that negotiators must consider carefully when determining the best approach.
但如今，在计划进行了一半时，我们却看不见实实在在的进展，上个月的谈判在可接受的伊朗铀浓缩水平和阿拉克（Arak）重水反应堆的未来等关键问题的讨论上没有取得任何成果。成果寥寥与伊朗最近宣布将在7月达成最终协议之间的鲜明反差产生了关于伊朗战略和目标的重要问题——在决定最佳方针时，谈判者必须小心对待这些问题。
