Evaluating two decades of US sanctions to curb Iran’s nuclear appetite, the US Congress’s Government Accountability Office recently concluded that the results are “unclear,” adding with candid obliqueness that “some evidence, such as foreign firms signing contracts to invest in Iran’s energy and Iran’s continued proliferation efforts, raise questions about the extent of the sanctions’ impact.”
美国国会政府职责办公室回顾了二十年来美国为限制伊朗的核子胃口而对其实施的制裁，最近得出结论说其效果“不明朗”，并且用客气的语调说：“外国公司签署合同投资于伊朗的能源、伊朗继续扩散等证据对于制裁效果的大小提出了疑问。”
