His comment on Sir Edward Grey's efforts for peace is characteristic: "England claims that she did everything possible to preserve the peace. It cannot be denied that Grey made a series of mediation proposals. But mere good-will is not everything. It is much more important to weigh their practical importance, and the goal at which they aimed: Whether they were intended to preserve the world's peace under conditions honourable for all parties, or calculated to obtain for the _Entente_ a one-sided diplomatic victory which would have established its future predominance."[199] [Footnote 199: "Deutschland und der Weltkrieg," p. 544.] "Grey considered the moment suitable for a mediation proposal. On the evening of July 26th, after obtaining Russia's consent, he proposed to the Governments of France, Germany and Italy that their London ambassadors should meet in London to confer on a peaceful solution of the conflict. "The proposal was unacceptable to Austria, because it would have been an indirect recognition on her part of Russia's interest in the conflict. "Only those who had followed the growing intimacy of the mutual obligations between the Entente Powers, and their organization to a 'London Centre' during the summer of 1914, are able to estimate the role--to say nothing of Italy--which Russia's two comrades would have played in the conference. During its course Russia would have continued her military preparations, while Germany would have had to pledge herself not to mobilize. "Finally, no unprejudiced observer would dare assert that the man (Sir Edward Grey) who was ready to transform himself at a suitable opportunity into an ally of Russia, would have been an impartial chairman in a conference held under the pressure of a Russian mobilization. The more one thinks about this mediation proposal the more convinced one becomes, that it would at least have worked for a diplomatic victory for the Entente Powers. "Grey put the whole machinery of the Triple Entente in motion in order to force back Germany and Austria-Hungary along the whole line."[200] [Footnote 200: Ibid., p. 545 _et seq_.] An analysis of Professor Oncken's theses gives the following results: First, Britain's efforts to preserve peace are admitted, but he fails to mention any friendly advances to meet them. Secondly, the fundamental principle underlying the Germanic attitude is again exposed, viz., that Russia had no right to intervene in a question affecting the balance of power in the Balkans and in Europe (_vide_, p. 63). Thirdly, a diplomatic struggle was in progress along the whole line, between the two groups of Powers.
