"This point of view, applied to the present case, indicates prohibition of the export of arms."
Although during the war all Notes were at once made public, the American Government were very annoyed at my publishing this memorandum, which in any case would have met with no success. The agitation for the prohibition of the export of arms and munitions was vigorously pressed, and in spite of the "_Lusitania_ incident" never completely subsided. But the American Government held to their point of view, which they explained to me on the 21st April, as follows:
"In the third place, I note with sincere regret that, in discussing the sale and exportation of arms by citizens of the United States to the enemies of Germany, Your Excellency seems to be under the impression that it was within the choice of the Government of the United States, notwithstanding its professed neutrality and its diligent efforts to maintain it in other particulars, to inhibit this trade, and that its failure to do so manifested an unfair attitude toward Germany. This Government holds, as I believe Your Excellency is aware, and as it is constrained to hold in view of the present indisputable doctrines of accepted international law, that any change in its own laws of neutrality during the progress of a war which would affect unequally the relations of the United States with the nations at war would be an unjustifiable departure from the principle of strict neutrality by which it has consistently sought to direct its actions, and I respectfully submit that none of the circumstances urged in Your Excellency's memorandum alters the principle involved. The placing of an embargo on the trade in arms at the present time would constitute such a change and be a direct violation of the neutrality of the United States. It will, I feel assured, be clear to Your Excellency that, holding this view and considering itself in honor bound by it, it is out of the question for this Government to consider such a course."
In the meantime, Colonel House returned from Europe without having met with any success, but he had opened useful personal relations. The Governments of all the combatant Powers then held the opinion that the time had not yet come when they could welcome the mediation of President Wilson. Colonel House, however, did not allow the lack of success of his first mission to deter him from further efforts, and remained to the last the keenest supporter of American mediation. Since this journey Colonel House and I became on very friendly and intimate terms, which should have helped to bring about such a peace.
