This book describes the creation of a new economy in the Soviet Union from 1930 to 1945. The Red Army defeated the Germans in World War II with equipment produced by that economy and not with masses of untrained men as has been often argued. The Soviet weapons were produced in factories designed and built under the direction of American engineers in the 1930s. Also, the Weimar Republic played a part in the creation of the Red Army by providing aviation and tank training schools and technical assistance to the developing armaments industry. Dunn argues that if France had been invaded by the Allies in 1943 rather than in 1944, the post-war world would have been less advantageous to the Soviet Union.
