" The kind of thinking required for the successful conduct of foreign policy must at times be diametrically opposed to the kind of considerations by which the masses and their representatives are likely to be moved. The peculiar qualities of the statesman's mind are not always likely to find a favorable response in the popular mind. The statesman must think in terms of the national interest, conceived as power among other powers. The popular mind, unaware of the fine distinctions of the statesman's thinking, reasons more often than not in the simple moralistic and legalistic terms of absolute good and absolute evil. The statesman must take the long view, proceeding slowly and by detours, paying with small losses for great advantage; he must be able to temporize, to compromise, to bide his time. The popular mind wants quick results; it will sacrifice tomorrow's real benefit for today's apparent advantage. "
