The initiative of the Five Year Plan and of the accelerated collectivization belongs entirely to the Left Opposition, in uninterrupted and sharp struggles with the Stalinists. Not having the possibility of occupying myself here with long historical researches, I will limit myself to a single illustration. The Dnieprostroy is considered with right as the highest achievement of Soviet industrialization. Yet [Joseph] Stalin and his followers ([Clim] Voroshilov and others) a few months before the beginning of the work were decided opponents of the Dnieprostroy plan.
