The present war shows us that the factors of skill and morale, while independent of each other, are closely linked together, and react upon each other. Nothing establishes a good morale more than does the knowledge of exceeding skill; and nothing promotes skill more than does an enthusiastic and firm morale. But superadequateness of preparation has a value greater than in merely insuring victory with minimum loss to ourselves, in case war comes, because it exerts the most potent of all influences in preventing war, since it warns an enemy against attacking. At the present day, the laws of victory and defeat are so well understood, and the miseries resulting from defeat are so thoroughly realized, that no civilized country will voluntarily go to war, except for extraneous reasons, if it realizes that the chances of success are small. And as the cumulative consequences of defeats are also realized, and as no country is apt to assume that the morale and skill of its forces are measurably greater than those of a probable antagonist, no country and no alliance is apt to provoke war with a nation whose armed forces are superior in number of units of personnel and material; unless, of course, the nation is markedly inferior in morale and skill, as the Persians were to the legions of Alexander. It is often insisted that superadequacy in armed force tends to war instead of peace, by inducing a country to make war itself; that the very principles which deter a weak country from attacking a strong country tend to make a strong country attack a weak one. There is some truth in this, of course, and history shows many cases of strong countries deliberately attacking weak ones for the purpose of conquest.
