History tends to be unkind to the unlucky, but historians also judge leaders in terms of the causes of their luck. Good coaches analyze their game and their opponent’s game, so that they can capitalize on errors and benefit from “good luck.”
历史往往对不幸者缺乏仁慈，但历史学家也会就运气的原因对领袖人物进行评判。好教练分析本方和对手的比赛，以便利用对手的错误收获“好运气”。相比之下，鲁莽地考验现实及不必要地冒险往往是“坏运气”的部分理由。未来的历史学家很可能因此追究布什的责任。
