If we're looking at Iran, the president of the United States we would like to think, may have some influence -- certainly the president in Iran has some influence -- but we make a mistake if we just pay attention to the person at the top of the power ladder because that person doesn't know much about Iran, or about energy policy, or about health care, or about any particular policy.
如果我们研究伊朗，我们就会发现 美国总统会有一定的影响力 当然伊朗的总统也有一定的影响力 但我们会犯一个错误 当我们只关心决策层的领导 因为那个领导人不一定理解伊朗 抑或能源政策 或者医疗政策 甚至有可能不了解任何的政策
