Why did the US abandon its neutrality and choose to enter world war 1 on the side of the allies in 1917?

The United States abandoned its neutrality and entered World War I in 1917 primarily due to unrestricted submarine warfare by Germany, which threatened American lives and commerce. The sinking of ships like the Lusitania and the interception of the Zimmermann Telegram, which proposed a German-Mexican alliance against the U.S., further fueled public and political support for joining the Allies. Additionally, there was a desire to protect American economic interests and promote democratic values against autocratic regimes. These factors combined ultimately led President Woodrow Wilson to seek a declaration of war against Germany.
