The answer lies in the accentuation of the last four words, which can only mean that, but for the American supply of arms, the Allies, from lack of ammunition, would speedily be defeated, _i. e._ America is to co-operate in preserving for that country which has most extensively and actively prepared for war, the full and lasting advantage of that preparation. That would put a premium on war preparations--on an armed and therefore necessarily precarious peace--since it is but human nature that, given a difference which he considers serious enough for ground for a quarrel, a man armed to the teeth would be less inclined to settle the matter peaceably than one who is not so well prepared for a fight. Apart from this, the German complaint about the prolongation of the war through the American supply of arms is proof in itself that the refusal of such supplies would constitute a positive act of partiality in favour of Germany. And the great majority of Americans are convinced that the ruling powers of Germany and Austria, though not perhaps the people themselves, are responsible for the outbreak of the war; that they have sinned against humanity and justice; that at least France and England did not want war; that therefore its advent found them in a comparatively unprepared state, and that it would constitute a decided, serious and unjustifiable action of far-reaching effect _against the Allies_ if America were to put an embargo on war munitions--especially so in view of the fact that as a direct consequence of the treaty-defying invasion of Belgium you are in possession of the Belgian arms factories and iron mines and of about 75 per cent. of all the ore-producing capacity of France. For neutrals to supply war materials to belligerents is an ancient, unquestioned right, recognized by international law and frequently practised by yourselves. To alter, during the course of a war, a practice sanctioned by the law of nations and hitherto always followed, would constitute a flagrant breach of neutrality, in that it would necessarily help one side and harm the other. The fact that at one time we forbade the export of arms to Mexico affords no argument in favour of the German contention, for there it was not a case of war between nations, but of civil war. There was also the danger that such arms might eventually be used against America herself, given the possibility that intervention by us in Mexico might later on become necessary.
