But, at least for America, perhaps the most important lesson of 9/11 is that US foreign policy should follow the counsel of President Dwight Eisenhower a half-century ago: Do not get involved in land wars of occupation, and focus on maintaining the strength of the American economy.
但至少对美国人来说，或许9·11事件最大的教训就是美国的外交政策应当遵从前总统艾森豪威尔半个世纪前的忠告：不要卷入占领他国领土的战争，而是要把注意力放在增强美国经济之上。
