I very warmly appreciate your kind and frank letter of to-day, and feel that it calls for an equally frank reply. You are right in assuming that I shall do everything in my power to keep the United States out of war. I think the country will feel no uneasiness about my course in that respect. Through many anxious months I have striven for that object, amid difficulties more manifold than can have been apparent upon the surface, and so far I have succeeded. I do not doubt that I shall continue to succeed. The course which the central European powers have announced their intention of following in the future with regard to undersea warfare seems for the moment to threaten insuperable obstacles, but its apparent meaning is so manifestly inconsistent with explicit assurances recently given us by those powers with regard to their treatment of merchant vessels on the high seas that I must believe that explanations will presently ensue which will put a different aspect upon it. We have had no reason to question their good faith or their fidelity to their promises in the past, and I for one feel confident that we shall have none in the future. But in any event our duty is clear. No nation, no group of nations, has the right, while war is in progress, to alter or disregard the principles which all nations have agreed upon in mitigation of the horrors and sufferings of war; and if the clear rights of American citizens should very unhappily be abridged or denied by any such action we should, it seems to me, have in honour no choice as to what our own course should be. For my own part I cannot consent to any abridgment of the rights of American citizens in any respect. The honour and self-respect of the nation is involved. We covet peace, and shall preserve it at any cost but the loss of honor. To forbid our people to exercise their rights for fear we might be called upon to vindicate them would be a deep humiliation, indeed. It would be an implicit, all but an explicit, acquiescence in the violation of the rights of mankind everywhere and of whatever nation or allegiance. It would be a deliberate abdication of our hitherto proud position as spokesmen, even amid the turmoil of war, for the law and the right. It would make everything this government has attempted and everything that it has accomplished during this terrible struggle of nations meaningless and futile.
