On April 2, 1917, Congress having been called in special session, President Wilson appeared before a joint session of both houses and in an address worthy of its historical importance asked for a formal declaration that a state of war existed with Germany, owing to the ruthless and unrestricted submarine campaign. He recommended the utmost practical co-operation with the Entente Allies in counsel and action; the extension of liberal financial credit to them, the mobilization of all the material resources of the United States for the purpose of providing adequate munitions of war, the full equipment of the Navy, especially in supplying it with means for dealing with submarines, and the immediate enrollment of an army of 500,000 men, preferably by a system of universal service, to be increased later by an additional army of equal size. The President took pains to point out that in taking these measures against the German government, the United States had no quarrel with the German people, who were innocent, because kept in ignorance of the lawless acts of their autocratic government, which had become a menace not only to the peace of the world, but to the cause of fundamental human liberty. The object of the United States, said the President, was to vindicate the principles of peace and justice as against selfish and autocratic power, and to insure the future observance of these principles. After due debate the following joint resolution, declaring war with Germany was adopted by the Senate and House of Representatives and signed by the President on April 6, 1917: "Whereas, the imperial German government has committed repeated acts of war against the government and the people of the United States of America; therefore, be it "Resolved, by the Senate and House of Representatives of the United States of America in Congress assembled, That the state of war between the United States and the imperial German government which has thus been thrust upon the United States is hereby formally declared; and that the President be, and he is, hereby authorized and directed to employ the entire naval and military forces of the United States and the resources of the government to carry on war against the imperial German government; and to bring the conflict to a successful termination, all of the resources of the country are hereby pledged by the Congress of the United States." THE PRESIDENT PROCLAIMS WAR. Immediately after signing the resolution of Congress, President Wilson issued a formal proclamation of war, embodying in it an earnest appeal to all American citizens "that they, in loyal devotion to their country, dedicated from its foundation to the principles of liberty and justice, uphold the laws of the land and give undivided and willing support to those measures which may be adopted by the constitutional authorities in prosecuting the war to a successful issue and in obtaining a secure and just peace."
