American finance and Allied capacity in the First World War

Would the Allies have won the First World War without American money?

American finance was very useful, but the issue is more complex than treating it as the sole cause of victory, and the United States was not yet the industrial arsenal it became in the next war.

American finance was important without being the only explanation for Allied victory. Canadian funding and other sources complicate a single-cause account, while reduced loans might have slowed Allied stockpiling or delayed the final offensives. The United States entered the First World War with limited defence preparation, so American industry could not expand quickly enough to equip the American Expeditionary Force on its own. The comparison with the Second World War warns against projecting the later image of the United States as the arsenal of democracy backward onto 1917.
