The event that most influenced President Woodrow Wilson's decision to enter World War I was the resumption of unrestricted submarine warfare by Germany in early 1917. This policy threatened American shipping and lives, particularly with incidents like the sinking of the Lusitania in 1915 still fresh in memory. Additionally, the interception of the Zimmermann Telegram, in which Germany sought to entice Mexico into an alliance against the United States, further galvanized public opinion and pushed Wilson to seek a declaration of war in April 1917.
