Best Answer - Chosen by Asker:

All nations had run out of manpower!. Although US troops did very little materially to win the war, they put a lot of pressure on Germany to try to win the war in 1918, resulting in the 'do or die' Spring Offensive!.

With America in the war, the Allies just had to hold on, time was against Germany!.
