The number-one cause of American involvement in the Great War was unrestricted submarine warfare by the Germans. After the sinking of the Sussex in March of 1916, President Woodrow Wilson threatened to rescind all diplomatic relations with Germany unless the submarines stopped firing on neutral vessels. All the Germans had to do was bomb another ship, and that happened within the first two weeks of March, 1917. (In the interim, the US was made aware of the so-called Zimmerman Note, or Zimmerman telegram, in which Germany proposed to Mexico an alliance whereby Mexico would take Germany's side against the US, with an eye to regaining territory ceded to the US).

Four unarmed merchant vessels were attacked, and American lives were lost. Before this point, Wilson had made the threat of war if Germany overtly attacked American vessels, and on April 6 final approval for a declaration of war came from Congress.
