华盛顿— 特朗普总统正向伊朗施压，要求其缩减核计划，否则将面临潜在的军事打击。这一问题困扰了美国两党总统数十年。
伊朗否认有核武器野心，但其浓缩铀储备不断增加，纯度已接近制造炸弹所需的水平。特朗普总统去年6月下令袭击了伊朗三个关键核设施，但不到一年后的今天，总统暗示军事行动可能再次被提上日程。

Mr. Trump ordered strikes on a trio of key Iranian nuclear sites last June, but now, less than a year later, the president has suggested military action is on the table again.
