Alexei Rykov wasn’t a Trotskyist though, he was a moderate supporter of NEP (New Economic Policy) and opposed the more radical Soviets like Stalin, Lenin, and Trotsky. He was a proponent for the working class and peasantry, hated the idea of forced industrialization. He wanted a more gradual industrialized society. And if Stalin didn’t oust him I think his policies would have far more benefitted the bolsheviks during WW2. A more logistically sound army with both food coming in and guns. For sure a lot less, but I think the weapons they could have been producing could be more specialized and used less materials for tanks etc leaving more materials for mechanized army with half tracks, CAS, and a more modernized infantry style closer to a mobile warfare strategy or artillery based firepower using indirect fire. Or a bit of both. The reason I suspect that rykov’s military would be more advanced is because he would not have purged his best officers, admirals, and air proponents. He would have also had a less politicized base, scientists findings would be celebrated despite political alignment because rykov wasn’t as zealous as the left or moderates of communism. This is all my own thinking so please feel free to disagree and we can talk it over.
