The preparation of the Pangerman plan has required for over twenty years a huge propaganda among the German masses as well as a world-wide organization. How is it that this plan has been ignored in its nature and in its extent by the diplomats of France, England and Russia? Such, however, has been the case, for otherwise the war could not have come upon these three powers as a surprise. We deal here with a matter which at first sight seems improbable and which, therefore, needs explanation. The diplomatic agents of the Allies are certainly not inferior personally to those of William II., but the Kaiser’s foreign service, as a whole, includes novel instruments of observation and influence by which, for the last twenty years, the Government of Berlin has seconded its official diplomacy without allowing the connexion between it and them to transpire. None of the Allied countries have employed similar instruments, the result being that the Entente is considerably inferior in this department of foreign policy. * * * * * The Pangerman plan is founded on a very exact knowledge of all political, ethnographical, economic, social, military and naval problems, not only of Europe, but of the whole world; the Germans have acquired that knowledge by means of an intense labour of over twenty-five years. But this task has not been performed by the official German diplomats; it has been carried out either by the members of the _Alldeutscher Verband_, the Pangerman Union, or by the agents of the German secret service, which has been enormously extended. These agents might be called connecting links between the regular spies and the official diplomats; Baron von Schenk, who worked at Athens from 1915-1916, is a sample of that category of agents who have studied methodically all the root questions of the Pangerman plan, who have prepared means to delude the minds of neutrals, to paralyze the revolt of the Slavs in Austria-Hungary, to corrupt all such neutral individuals or neutral newspapers as were susceptible of corruption, etc. After these numerous agents had made their reports, and when once these had been examined and summarized, they were sent to the Wilhelmstrasse, to the great German General Staff, whose concerted operations are always so combined as to answer both to political and to military needs. At the same time the reports reached William II.’s private study, and his brain was thus able to store up all technical means necessary for the achievement of his plan of domination. Was the diplomatic corps of the Allies so well served that it could grasp in its universal significance the immense work of preparation accomplished by the secret Pangerman agents? Indeed, they were not properly supplied with the right tools for such a task, and we shall see why it was so.
