Somewhat to the discomfort of Iran's president, Mahmoud Ahmadinejad, who had bolstered his domestic support by vilifying America as an aggressor, Mr Obama has proposed holding talks about nuclear affairs, removing a precondition that Iran first abandon enrichment of uranium.

然而，这对伊朗总统马哈茂德艾哈迈迪-内贾德来说，多少有些不快。此前，内贾德通过中伤美国称其是侵略者而巩固了他的国内支持力。奥巴马提议就核问题举行谈话，并取消伊朗必须首先放弃铀浓缩的前提条件。
