The allies, which included the United States, England, France, and Russia were successful in defeating the axis powers which included Italy, Germany, and Japan. World War II played a major role in United States' history. From an economic view, it brought the.
United States out of the depression of the 1930's. The government made industries for war production to produce strategic war materials. .

Despite Roosevelt's efforts to end the depression with the New Deal policies, it was not until World War II that the United States emerged from its long economic depression.
