The carrying over of Christian ideals into national and international politics is equally indispensable. In the sphere of international affairs in particular, while other nations have, for the most part, rendered official lip-service from time to time to ideals of international morality, it has been reserved for Germany to declare openly for the repudiation of "sentiment," and for a policy of undisguised cynicism and _real-politik_. The doctrine that the state as such is exempt from moral obligation towards its neighbours, and that the whole political duty of man is exhausted in the service of his country and the promotion of her purely selfish interests and "will to power," has been exhibited in action by the Prussian Government in such a fashion as to incur the moral reprobation of the world. The cynical doctrines of _real-politik_, the belief that the "interests" of the state are in politics and diplomacy paramount, and that "the foreigner" is a natural enemy, the belief that in all international relationships selfish and self-interested considerations must really determine policy, are unfortunately by no means unrepresented, though they are not unchallenged, in the political life of other countries besides Germany. There are influential publicists in England to-day the _principles_ of whose political thinking are really Prussian. It remains to be seen whether, when the time comes for peace to be made between the nations, the forces of international idealism will prove strong enough to carry the day, or whether we shall have a merely vindictive and "realist" peace which will contain within itself the seeds of future wars. There can be no question but that a Christian man is bound to stand both for the freedom of oppressed nationalities and for the right of all peoples freely to determine their own affairs, and also for the duty of nations as of individuals to love their neighbours as themselves, and to seek primarily not their own but each other's good. If these professions are to be more than nominal they must mean a readiness for national sacrifices and for national unselfishness in time of peace as in time of war. CHAPTER IX CHRISTIANITY AND WAR Christianity is opposed to war, in the sense that if men and nations universally behaved as Christians, wars would cease. The ideal of the Kingdom of GOD involves the reign upon earth of universal peace. War is, therefore, in itself, an unchristian thing. It is, moreover, a barbarous and irrational method of determining disputes, since the factors which humanly speaking are decisive for success in war, viz. the organized and unflinching use of superior physical force, are in principle irrelevant to the rights or wrongs of the cause which may be at stake. The victories of might and right do not invariably coincide.
