The document summarizes the key events that drew the United States into World War I despite President Wilson's initial goal of neutrality. It discusses Wilson's 1916 campaign slogan of keeping the U.S. out of the war. It then lists several events that unfolded and proved too difficult for Americans to ignore, including the sinking of the Lusitania in 1915 and the Zimmerman Telegram in 1917, which led Wilson to ask Congress to declare war on Germany in April 1917 in order to "Make the World Safe for Democracy."
