In early 1917, the United States was still neutral in the First World War. Meanwhile, German leaders were getting desperate – if they couldn’t find a way to break the war of attrition on the Western Front, the Allies would probably defeat them. The result was multiple gambles that staked everything on a quick victory with the risk of drawing the US into the war.
