to lose correspondingly, by confining the attack on France to the heavily fortified Franco-German frontier, and that as France and England knew they would be invited by the Belgians to enter Belgium if the Germans invaded it, the neutrality of Belgium had, as far as they were concerned, no real existence; (_d_) that as all treaties are valid only _rebus sic stantibus_, and the state of things which existed at the date of the Treaty of London (1839) had changed so much since then (Belgium is no longer menaced by France, at whom the treaty was aimed, and has acquired important colonies, for instance) that in 1870 Gladstone could not depend on it, and resorted to a special temporary treaty not now in force, the technical validity of the 1839 treaty is extremely doubtful; (_e_) that even if it be valid its breach is not a _casus belli_ unless the parties for reasons of their own choose to make it so; and (_f_) that the German national peril pleaded by the Imperial Chancellor in his Peer Gynt speech (the _durchhauen_ one), when he rashly but frankly threw away the strong technical case just stated and admitted a breach of international law, was so great according to received Militarist ideas in view of the Russian mobilization, that it is impossible for us or any other Militarist-ridden Power to feel sure ourselves, much less to convince others, that we should have been any more scrupulous in the like extremity. It must be added that nothing can extenuate the enormity of the broad fact that an innocent country has been horribly devastated because her guilty neighbors formed two huge explosive combinations against one another instead of establishing the peace of Europe, but that is an offence against a higher law than any recorded on diplomatic scraps of paper, and when it comes to judgment the outraged conscience of humanity will not have much patience with the naughty child's plea of "he began it."
