Answer:
British society was changed by its wartime experiences in other ways, too. State intervention was extended into areas such as rent control (1915), conscription (1916), price control (1917), rationing (1918) and even alcohol dilution.
The entry of the United States was the turning point of the war, because it made the eventual defeat of Germany possible. It had been foreseen in 1916 that if the United States went to war, the Allies' military effort against Germany would be upheld by U.S. supplies and by enormous extensions of credit.
