The President's attempt thus cleared the air. It made plain to the majority of Americans that in sympathy, at least, the United States must be definitely aligned with Great Britain and France. Furthermore the replies of the belligerents gave to Wilson an opportunity to inform the world more definitely of the aims of the United States, in case it should be drawn into the war. This he did in a speech delivered to the Senate on January 22, 1917. America would play her part in world affairs, he said, but the other nations must clearly understand the conditions of our participation. The basis of peace must be the right of each individual nation to decide its destiny for itself without interference from a stronger alien power. "I am proposing as it were, that the nations should with one accord adopt the doctrine of President Monroe as the doctrine of the world: that no nation should seek to extend its polity over any other nation or people, but that every people should be left free to determine its own polity, its own way of development, unhindered, unthreatened, unafraid, the little along with the great and powerful." Instead of the old system of alliances there should be a general concert of powers: "There is no entangling alliance in a concert of powers. When all unite to act in the same sense and with the same purpose, all act in the common interest and are free to live their own lives under a common protection." As the result of such a concert no one power would dominate the sea or the land; armaments might safely be limited; peace would be organized by the major force of mankind. As a guarantee of future justice and tranquillity the terms that settled the present war must be based upon justice and not be of the sort ordinarily dictated by the victor to the vanquished. It must be a "peace without victory." Thus while Wilson warned Germany that her ambitions for continental domination would not be tolerated, he also warned the Allies that they could not count upon the United States to help them to crush Germany for their selfish individual purposes.
This speech, despite the unfortunate phrase, "peace without victory," was hailed in all liberal circles, amongst the Allies and in the United States, as a noble charter of the new international order. Wilson had expressed the hope that he was "speaking for the silent mass of mankind everywhere who have as yet had no place or opportunity to speak their real hearts out concerning the death and ruin they see to have come already upon the persons and the homes they hold most dear." This hope was doubtless realized. The first reaction in France and England was one of rather puzzled contempt, if we may judge by the press. But the newspaper writers soon found that what Wilson said many people had been thinking, and waiting for some one to say. Hall Caine wrote to the Public Ledger, "Let President Wilson take heart from the first reception of his remarkable speech. The best opinion here is one of deep feeling and profound admiration." From that moment Wilson began to approach the position he was shortly to hold—that of moral leader of the world.
The President had been anxious to make plain his principles, before the United States became involved in the conflict through the withdrawal of German submarine pledges, as well as to convince the world that every honest effort possible had been made to preserve the peace. He was only just in time. Already the advocates of ruthlessness in Berlin had persuaded the Kaiser and Bethmann-Hollweg. They recognized that the resumption of unrestricted submarine warfare meant, in all probability, the intervention of the United States, but they recked little of the consequences. On January 16, 1917, the Kaiser telegraphed: "If a break with America is unavoidable, it cannot be helped; we proceed." The same day the Secretary of Foreign Affairs, Zimmermann, telegraphed to the German Minister in Mexico, instructing him to form an alliance with Mexico in the event of war between Germany and the United States, and to offer as bribe the States of New Mexico, Arizona, and Texas; he also suggested the possibility of winning Japan from her allegiance to the Entente and persuading her to enter this prospective alliance.
On the 31st of January, von Bernstorff threw off the mask. The German Ambassador informed our Government of the withdrawal of the Sussex pledge. On and after the 1st of February, German submarines would sink on sight all ships met within a delimited zone around the British Isles and in the Mediterranean. They would permit the sailing of a few American steamships, however, provided they followed a certain defined route to Falmouth and nowhere else, and provided there were marked "on ship's hull and superstructure three vertical stripes one meter wide, to be painted alternately white and red. Each mast should show a large flag checkered white and red, and the stern the American national flag. Care should be taken that during dark, national flag and painted marks are easily recognizable from a distance, and that the boats are well lighted throughout." Other conditions followed. There might sail one steamship a week "in each direction, with arrival at Falmouth on Sunday and departure from Falmouth on Wednesday." Furthermore the United States Government must guarantee "that no contraband (according to the German contraband list) is carried by those steamships." Such were the orders issued to the United States. No native American could escape the humor of the stipulations, which for a moment prevented the national irritation from swelling into an outburst of deep-seated wrath.
There seems to have been little hesitation on the part of the President. On April 19, 1916, he had warned Germany that unrestricted submarine warfare meant a severance of diplomatic relations. Now, on February 3, 1917, addressing both houses of Congress, he announced that those relations had been broken. Von Bernstorff was given his papers and the American Ambassador, James W. Gerard, was recalled from Berlin. No other course of action could have been contemplated in view of the formality of the President's warning and the definiteness of Germany's defiance. Despite the protests of scattered pacifists, the country was as nearly a unit in its approval of Wilson's action as its heterogeneous national character permitted. All the pent-up emotions of the past two years found expression in quiet but unmistakable applause at the departure of the German Ambassador.
The promptitude of the President's dismissal of von Bernstorff did not conceal the disappointment which he experienced from Germany's revelation of her true purposes. He seems to have hoped to the end that the German liberals would succeed in bringing their Government to accept moderate terms of peace. Even now he expressed the hope that Germany's actions would not be such as to force the United States into the War: "I refuse to believe that it is the intention of the German authorities to do in fact what they have warned us they will feel at liberty to do.... Only actual overt acts on their part can make me believe it even now." But "if American ships and American lives should in fact be sacrificed by their naval commanders in heedless contravention of the just and reasonable understandings of international law and the obvious dictates of humanity, I shall take the liberty of coming again before the Congress to ask that authority be given me to use any means that may be necessary for the protection of our seamen and our people in the prosecution of their peaceful and legitimate errands on the high seas. I can do nothing less. I take it for granted that all neutral governments will take the same course." He was careful, moreover, to underline the fact that his action was dictated always by a consistent desire for peace: "We wish to serve no selfish ends. We seek merely to stand true alike in thought and in action to the immemorial principles of our people.... These are the bases of peace, not war. God grant we may not be challenged to defend them by acts of willful injustice on the part of the Government of Germany!"
But Germany proceeded heedlessly. Warned that American intervention would result only from overt acts, the German Admiralty hastened to commit such acts. From the 3d of February to the 1st of April, eight American vessels were sunk by submarines and forty-eight American lives thus lost. Because of the practical blockade of American ports which followed the hesitation of American shipping interests to send boats unarmed into the dangers of the "war zone," President Wilson came again to Congress on the 26th of February to ask authority to arm merchant vessels for purposes of defense. Again he stressed his unwillingness to enter upon formal warfare and emphasized the idealistic aspect of the issue: "It is not of material interests merely that we are thinking. It is, rather, of fundamental human rights, chief of all the right of life itself. I am thinking not only of the rights of Americans to go and come about their proper business by way of the sea, but also of something much deeper, much more fundamental than that. I am thinking of those rights of humanity without which there is no civilization.... I cannot imagine any man with American principles at his heart hesitating to defend these things."
Blinded by prejudice and tradition, a handful of Senators, twelve "willful men," as Wilson described them, blocked, through a filibuster, the resolution granting the power requested by the President. But the storm of popular obloquy which covered them proved that the nation as a whole was determined to support him in the defense of American rights. The country was stirred to the depths. The publication of the plans of Germany for involving the United States in war with Mexico and Japan came merely as added stimulus. So also of the story of the cruelties heaped by the Germans on the American prisoners of the Yarrowdale. There was so much of justice in the cause that passion was notable by its absence. When finally on the 17th of March news came of the torpedoing of the Vigilancia without warning, America was prepared and calmly eager for the President's demand that Congress recognize the existence of a state of war.
The demand was made by Wilson in an extraordinary joint session of Congress, held on the 2d of April. In this, possibly his greatest speech, he was careful not to blur the idealistic principles which, since the spring of 1916, he had been formulating. War existed because Germany by its actions had thrust upon the United States the status of belligerent. But the American people must meet the challenge with their purpose clearly before them. "We must put excited feeling away. Our motive will not be revenge or the victorious assertion of the physical might of the nation, but only the vindication of right, of human right, of which we are only a single champion.... The wrongs against which we now array ourselves are no common wrongs; they cut to the very roots of human life." He went on to define the objects of the war more specifically, referring to his earlier addresses: "Our object now, as then, is to vindicate the principles of peace and justice in the life of the world as against selfish and autocratic power and to set up amongst the really free and self-governed peoples of the world such a concert of purpose and action as will henceforth ensure the observance of those principles." Democracy must be the soul of the new international order: "A steadfast concert for peace can never be maintained except by a partnership of democratic nations. No autocratic government could be trusted to keep faith within it or observe its covenants.... Only free peoples can hold their purpose and their honor steady to a common end and prefer the interests of mankind to any narrow interest of their own." Because the existing German Government was clearly at odds with all such ideals, "We are glad, now that we see the facts with no veil of false pretense about them, to fight thus for the ultimate peace of the world and for the liberation of its peoples, the German people included: for the rights of nations great and small and the privilege of men everywhere to choose their way of life and of obedience. The world must be made safe for democracy. Its peace must be planted upon the tested foundations of political liberty."
Wilson thus imagined the war as a crusade, the sort of crusade for American ideals which Clay and Webster once imagined. He was in truth originating nothing, but rather resuscitating the generous dreams which had once inspired those statesmen. In conclusion, he reiterated his love of peace. "But the right is more precious than peace, and we shall fight for the things which we have always carried nearest our hearts,—for democracy, for the right of those who submit to authority to have a voice in their own governments, for the rights and liberties of small nations, for a universal dominion of right by such a concert of free peoples as shall bring peace and safety to all nations and make the world itself at last free." At the moment of the declaration of war Wilson was still the man of peace, and the war upon which the nation was embarking was, in his mind, a war to ensure peace. To such a task of peace and liberation, he concluded in a peroration reminiscent of Lincoln and Luther, "we can dedicate our lives and our fortunes, everything that we are and everything that we have, with the pride of those who know that the day has come when America is privileged to spend her blood and her might for the principles that gave her birth and happiness and the peace which she has treasured. God helping her, she can do no other."
