"How did the United States help bring about the Allied victory in 1918?" (NOT BATTLES, but how did the U. S. help bring about the Allied victory in 1918? What did they do to help?) I need four things they did to help

There wasn't a victory.the Europeans exhausted themselves. The US only prolonged the conflict for about a year, at which time the Europeans thought that an armistice was the only way to not perish. The real victory came in 1919, when President Wilson went to Versailles to hold court and chop up the map of the world in the image of a racist, imperialist, white, Western European/American hegemony, complete with “reparations” that assured the flow of gold primarily out of Germany, and primarily into the US. Wilson was able to hold the dominant position at Versailles because the US was one nation that was not utterly spent, in terms of men and material and resources.
