REASONS FOR ENTRY OF THE
UNITED STATES INTO WORLD WAR I

would attack any ships without warning—a violation of international law.

were taking a risk. Once the ship was close to Britain, a German U-boat (an Unterseeboot or
submarine) launched a torpedo attack, sinking the Lusitania. 128 Americans on board were killed.
President Wilson was angry but still kept the United States out of war. He was re-elected in 1916 with
the slogan, “He kept us out of war.”

January 1917: The German foreign secretary, Arthur Zimmermann, sent a telegram to Mexico asking
Mexico to become an ally of Germany. In return, it said that Germany would help Mexico win back
lands lost to the United States during the Mexican War.
April 1917: Once Americans were aware of this telegram, they were outraged. President Wilson declared
war on Germany.
The USA delayed entering the war because of the USA’s long history of isolationism.
