The Soviet Union and the countries of eastern Europe were not exempt from the cycle of prosperity, growth, economic stagnation, and social and political unrest, even though they could prevent the unrest from getting out of hand or from being made known outside their borders.
Problems for the Soviet leadership proved to be fully as difficult as those faced by the Western democracies, but totalitarian states did not have to engage in divisive public debate over how to allocate resources.
Thus the Soviet Union was free to concentrate on postwar industrial recovery and parity in the arms race.
