Following the great depression, in which country did economic recovery occur most quickly?

The Soviet Union didn't trade much with countries that were not communist. For this, they didn't trade with America, Britain, and other places. If the Soviet Union was to be democratic, it would probably fall with the rest of the world. 

I hope this is good, the thing is the Soviet Union would've been getting back to a super power in a few short weeks.

After the Great Depression in the United States, America was able to rebuild the quickest because right after a decade of economic depression we were involved in World War ll. We then had to begin mass producing goods for the war effort which then resulted in thousands of factory jobs for previously unemployed people.

Contributing factors  leading  to the harlem renaissance were the great migration of african americans to northern cities, which concentratedambitious  people in places where they could encourage each  other, and the first world war, which had created new industrial work opportunities for tens of thousands of people.
