Who entrance of the US into war was promoted by?

The entrance of the United States into World War I was largely promoted by several factors, including German unrestricted submarine warfare, which threatened American shipping and lives, particularly after the sinking of the Lusitania in 1915. Additionally, the interception of the Zimmermann Telegram, in which Germany proposed a military alliance with Mexico against the U.S., further galvanized public and political support for war. President Woodrow Wilson, who initially advocated for neutrality, ultimately sought to protect American interests and promote democracy, leading to the U.S. declaration of war in April 1917.
