Wilson's second term was dominated by the American entry into World War I and that war's aftermath. In April 1917, when Germany resumed unrestricted submarine warfare, Wilson asked Congress to declare war in order to make "the world safe for democracy." Through the Selective Service Act, conscription sent 10,000 freshly trained soldiers to France per day by summer 1918. On the home front, Wilson raised income taxes, set up the War Industries Board, promoted labor union cooperation, regulated agriculture and food production through the Lever Act, and nationalized the nation's railroad system. In his 1915 State of the Union, Wilson asked Congress for what became the Espionage Act of 1917 and the Sedition Act of 1918, suppressing anti-draft activists. The crackdown was later intensified by Attorney General A. Mitchell Palmer to include expulsion of non-citizen radicals during the First Red Scare of 1919–1920. Wilson infused morality into his internationalism, an ideology now referred to as "Wilsonian"—an activist foreign policy calling on the nation to promote global democracy. In early 1918, he issued his principles for peace, the "Fourteen Points," and in 1919, following the signing of an armistice with Germany, he traveled to Paris, concluding the Treaty of Versailles. Wilson embarked on a nationwide tour to campaign for the treaty, which would have included U.S. entrance into the League of Nations, but was left incapacitated by a stroke in October 1919 and saw the treaty defeated in the Senate.
