Prussia, France, and England had all promised not to invade Belgium, because it was the safest way of invading France. But Prussia promised that if she might break in through her own broken promise and ours she would break in and not steal. In other words, we were offered at the same instant a promise of faith in the future and a proposal of perjury in the present.
Those interested in human origins may refer to an old Victorian writer of English, who in the last and most restrained of his historical essays wrote of Frederick the Great, the founder of this unchanging Prussian policy. After describing how Frederick broke the guarantee he had signed on behalf of Maria Theresa he then describes how Frederick sought to put things straight by a promise that was an insult. "If she would but let him have Silesia, he would, he said, stand by her against any power which should try to deprive her of her other dominions; as if he was not already bound to stand by her, or as if his new promise could be of more value than the old one." That passage was written by Macaulay; but so far as the mere contemporary facts are concerned, it might have been written by me.
Diplomacy That Might Have Been.
Upon the immediate logical and legal origin of the English interest there can be no rational debate. There are some things so simple that one can almost prove them with plans and diagrams, as in Euclid. One could make a kind of comic calendar of what would have happened to the English diplomatist if he had been silenced every time by Prussian diplomacy. Suppose we arrange it in the form of a kind of diary:
July 24—Germany invades Belgium.
July 25—England declares war.
July 26—Germany promises not to annex Belgium.
July 27—England withdraws from the war.
July 28—Germany annexes Belgium. England declares war.
July 29—Germany promises not to annex France. England withdraws from the war.
