Today Cameron was sent a reading entitled, "American Involvement in WWI: How the War Changed After America's Entry." It not only reinforced the reasons for America's entry into WWI (which we have discussed in several classes) it discussed how WWI changes during the one year of America's involvement. As a result of the United States entering World War, the war shifted, and the Allies began winning many battles against the Central Powers. As a result, on November 11, 1918, an armistice was signed, which brought the fighting to a halt. Eventually, the Treaty of Versailles was signed in 1919, which ended World War I and laid the groundwork for World War II.
