The entry into the war of a country that had long pursued a policy of neutrality under President Woodrow Wilson was influenced by Germany's continued unrestricted submarine warfare and the revelation of the Zimmermann Telegram, which contained a secret proposal to Mexico. The participation of the United States influenced the course of the war by providing the Entente side with significant manpower and economic resources and contributed to Entente superiority in the developments of 1918.
