As President George W. Bush argued about the war in Iraq, US President Lyndon Johnson predicted that defeat in Vietnam “would be renewed in one country and then another.” What Johnson failed to foresee were the domestic and regional constraints that would prevent the dominos from falling in the way he predicted.
就像乔治·W·布什为伊拉克战争所做的辩护一样，美国总统林登·约翰逊预测说在越南的失败“将在一个国家，然后又一个国家里重现”。约翰逊没有预测到的是某些国内和区域内的限制因素，这些因素将会阻止多米诺骨牌按他预计的方式滑落。
