A word or two as to the rôle of "friendship" in international relations. Courtesy and a certain measure of good faith are essential elements wherever civilized men come in direct contact; without them organized society would go to pieces. But these invaluable elements never yet of themselves settled real differences; they merely render the other factors of adjustment possible. Why should one expect courtesy and good-fellowship to settle grave political differences between English and Germans when they altogether fail to settle such differences between English and English? What should we say of a statesman professing to be serious who suggested that all would be well between President Wilson and the lobbyists concerning the tariff, between the Democrats and Republicans on protection, between the millionaire and the day laborer on the question of the income tax, and a thousand and one other things--that all these knotty problems would disappear, if only the respective protagonists could be persuaded to take lunch together? Is it not a little childish? Yet I am bound to admit that a whole school of persons who deal with international problems would have us believe that all international differences would disappear if only we could have enough junketings, dinner-parties, exchange visits of clergymen, and what not. These things have immense use in so far as they facilitate discussion and the elucidation of the policy in which the rivalry has its birth, and to that extent only. But if they are not vehicles of intellectual comprehension, if the parties go away with as little understanding of the factors and nature of international relationship as they had before such meetings took place, they have served no purpose whatsoever. The work of the world does not get done merely by being good friends with everybody; the problems of international diplomacy are not to be solved merely by a sort of international picnic; that would make the world too easy a place to live in.
