The evil element in nationalism under its many names, “Chauvinism,” “Jingoism,” “Prussianism,” is the one thing in our present European civilization that can and does produce the calamity of war. If our object is to prevent war, then, the way to do so is to purge Nationality of this evil. This we cannot do by any mechanical means, but only by a change of heart, by converting public opinion throughout Europe from “National Competition” to “National Cooperation.” Public opinion will never be converted so long as the present system of injustice remains in force, so long as one nation has less and another more than its due. The first step towards internationalism is not to flout the problems of nationality, but to solve them. [Sidenote: The map of Europe must be justly revised.] The most important practical business, then, of the conference that meets when war is over, will be the revision of the map of Europe.... [Sidenote: Otherwise no permanent settlement is possible.] If we do not think about nationality, it is simply because we have long taken it for granted, and our mind is focussed on posterior developments; but it is increasingly hard to keep ourselves out of touch with other countries, and though our blindness has been partly distraction, it has also been in part deliberate policy. We saw well enough that the present phase of the national problem in Europe carried in it the seeds of war. We rightly thought that war itself was the evil, an evil incomparably greater than the national injustices that might become the cause of it. We knew that, if these questions were opened, war would follow. We accordingly adopted the only possible course. We built our policy on the chance that national feeling could be damped down till it had been superseded in the public opinion of Europe by other interests, not because Nationalism was unjustified, but because it endangered so much more than it was worth. Knowing that we had passed out of the nationalist phase ourselves, and that from our present political point of view war was purely evil, we hoped that it was merely a question of time for the Continental populations to reach the same standpoint. Notably in Germany, the focus of danger, we saw social interests coming more and more to the front at the expense of militarism. We threw ourselves into the negative task of staving off the catastrophe in the interim, by a strenuous policy of compromise and conciliation, which has been successful on at least two critical occasions. Now that the evil has been too powerful and the catastrophe has happened, the reasons for this policy are dead. Nationalism has been strong enough to produce war in spite of us. It has terribly proved itself to be no outworn creed, but a vital force to be reckoned with. It is stronger on the Continent than social politics. It is the raw material that litters the whole ground. We must build it into our foundations, or give up the task, not only of constructive
