In January of 1917 the German's resumed the practice of Unrestricted Submarine Warfare. In the first weeks of March Germany sunk 5 unarmed US merchant ships. Previously in 1916, after Germany sank the Sussex a US merchant ship, the US threatened to enter the war, and Germany backed down. They promised not to sink merchant or passenger ships without warning. They kept this promise until 1917. Other immediate causes for US entering the war are the 1) Zimmerman Telegram (intercepted by British intelligence a note between Germany and Mexico proposing that the two countries align) and 2) the Russian Revolution.
