When WWI began, the US was largely divided on the issue on entering the war and remained neutral for the better part of it. However, when German U-Boats began attacking US ships, military or civilian, public opinion gradually turned against Germany. The final straw was when the US intercepted a transmission from Germany to Mexico telling them to attack the US to keep them out of the war. After that, the US joined the war.
