The immeasurable distance between the cause and the occasion was shown by the fact that Belgium was the first to suffer in an Austro-Serbian dispute; and the universal character of the issue was foreshadowed by the breach of its neutrality. Germany would not have planned for two years past an offensive through that inoffensive, unconcerned, and distant country, had the cause of the war been a murder at Serajevo. The cause was a comprehensive determination on the German part to settle international issues by the sword, and it involved the destinies of civilization. The blow was aimed directly or indirectly at the whole world, and Germany's only prospect of success lay in the chance that most of the world would fail to perceive its implications or delay too long its effective intervention. It was the defect of her self-idolatry and concentration that she could not develop an international mind or fathom the mentality of other peoples. She could not conceive how England would act on a "scrap of paper," and never dreamt of American participation. But she saw that Russia and France would inevitably and immediately be involved in war by the attempt at armed dictation in the Balkans, and that the issue would decide the fate of Europe. The war would therefore be European and could only be won by the defeat of France and Russia. Serbia would be merely the scene of local and unimportant operations, and, Russia being the slower to move, the bulk of the German forces were concentrated on the Rhine for the purpose of overwhelming France.
The condition of French politics was one of the temptations which led the Prussian militarists to embark upon the hazard. France had had her troubles with militarism, and its excesses over the Dreyfus case had produced a reaction from which both the army command and its political ally the Church had suffered. A wave of national secularism carried a law against ecclesiastical associations which drove religious orders from France, and international Socialism found vent in a pacifist agitation against the terms of military service. A rapid succession of unstable ministries, which the group system in French parliamentary politics encouraged, militated against sound and continuous administration; and in April 1914 a series of revelations in the Senate had thrown an unpleasant light upon the efficiency of the army organization. On military grounds alone there was much to be said for the German calculation that in six weeks the French armies could be crushed and Paris reached. But the Germans paid the French the compliment of believing that this success could not be achieved before Russia made her weight felt, unless the Germans broke the international guarantees on which the French relied, and sought in Belgium an easier and less protected line of advance than through the Vosges.
