We must not be blinded in politics by personal wishes and hopes, but must look things calmly in the face, and try to forecast the probable attitude of the other States by reference to their own interests.  Bismarck tells us that “Illusions are the greatest danger to the diplomatist.  He must take for granted that the other, like himself, seeks nothing but his own advantage.”  It will prove waste labour to attempt to force a great State by diplomatic arrangements to actions or an attitude which oppose its real interests.  When a crisis arises, the weight of these interests will irresistibly turn the scale.

When Napoleon III. planned war against Prussia, he tried to effect an alliance with Austria and Italy, and Archduke Albert was actually in Paris to conclude the military negotiations.[B] These probably were going on, as the French General Lebrun was in Vienna on the same errand.  Both countries left France in the lurch so soon as the first Prussian flag flew victoriously on the heights of the Geisberg.  A statesman less biassed than Napoleon would have foreseen this, since neither Austria nor Italy had sufficient interests at stake to meddle in such a war under unfavourable conditions.

[Footnote B:  When Colonel Stoffel, the well-known French Military Attache in Berlin, returned to Paris, and was received by the Emperor, and pointed out the danger of the position and the probable perfection of Prussia’s war preparations, the Emperor declared that he was better informed.  He proceeded to take from his desk a memoir on the conditions of the Prussian army apparently sent to him by Archduke Albert, which came to quite different conclusions.  The Emperor had made the facts therein stated the basis of his political and military calculations. (Communications of Colonel Stoffel to the former Minister of War, v.  Verdy, who put them at the service of the author.)]

France, in a similar spirit of selfish national interests, unscrupulously brushed aside the Conventions of Algeciras, which did not satisfy her.  She will equally disregard all further diplomatic arrangements intended to safeguard Germany’s commercial interests in Morocco so soon as she feels strong enough, since it is clearly her interest to be undisputed master in Morocco and to exploit that country for herself.  France, when she no longer fears the German arms, will not allow any official document in the world to guarantee German commerce and German enterprise any scope in Morocco; and from the French standpoint she is right.

The political behaviour of a State is governed only by its own interests, and the natural antagonism and grouping of the different Great Powers must be judged by that standard.  There is no doubt, however, that it is extraordinarily difficult to influence the political grouping with purely selfish purposes; such influence becomes possible only by the genuine endeavour to further the interests of the State with which closer relations are desirable and to cause actual injury to its opponents.  A policy whose aim is to avoid quarrel with all, but to further the interests of none, runs the danger of displeasing everyone and of being left isolated in the hour of danger.
