The document that I have linked here is then President Woodrow Wilson delivering  a speech to Congress on April 19, 1916 regarding the German attack on a French passenger ship called the Sussex.

Germany had a policy of unrestricted submarine warfare on armed ships but not passenger ships.  When the German U-Boats shot down the Sussex, the US had Germany make the Sussex Pledge which said that if Germany were to continue in this manner of firing on passenger ships, then the US would have no choice but to join the war in order to stop them.

In 1917, Germany felt that they could successfully destroy British shipping boats and end the war without the US having time to respond. They were very wrong. Upon the breaking of the Sussex Pledge, and a few other actions such as the Zimmerman note, the US joined World War I on the side of the Allies and Triple Entente.

The US was trying to maintain a stance of isolationism, but the Germans forced the US’s hand, and the US helped the Allies end the war.
