I am not sure how one could spend decades being entrusted with some of the top jobs in the Soviet government with no leadership qualities. What sources do you make that assessment on? And were they character attacks made during or after his expulsion by Khrushchev?
From what I have read about him, he seems to have been a capable organizer, had some truly dreadful ideas about agriculture (he thought Stalin's collectivization hadn't gone far enough and everything should be turned into state farms), had a few good ideas and had the outstanding qualities for leading the Soviets during WW2 of a) having been outside the Soviet Union and dealt with forrin people and b) being in one of the positions that a new leader might reasonably be chosen from if Stalin dies suddenly and a new boss has to be picked fast.
IIRC, Lenin called him as "Stone Ass" (and blamed for "shameful bureaucratism") and Bazanov (Бажанов, you can look for his memoirs, quite revealing) described him as, being a head of the Party secretariat, a
technical organizer of the system that Stalin used to get to power. The guy was an accomplished bureaucrat and he was seemingly
cultivating this image as a survival trait. Starting from 1930 he was a Chairman of the
Council of People's Commissars (formally, head of the government) but, just as was the case with Kalinin,
Chairman of the
Presidium of the
Supreme Soviet of the Soviet Union, aka, formal head of the state, this position meant little in the terms of independent activities. Being a capable organizer would not be enough if you are all the time organizing what you are ordered to organize.
Of course, as a head of a government,
formally, he would be the most eligible candidate (Kalinin being just a figurehead) but Zdhanov was a very strong figure who hold quit a few important positions, including, from 1938 Chairman of the Supreme Council of the RSFSR and a head of a Propaganda Department of the Central Committee and from 1940 membership in the Military Council of the Red Army.
Khruschev was, until 1938, the 1st Party Secretary of both Moscow region
and Moscow itself and in 1938 was made the 1st Secretary in Ukraine and full Politburo member in 1939. A purely Party figure with no management experience but most probably with a lot of the Party clientele in Moscow and, which would be a plus,
reputation of an easy to manipulate clown. In the case of the internal fight for the top position may look like a suitable compromise figure.
As at least theoretical possibility, if Stalin is dead by 1939, Woroshilov (who is not yet compromised by a Finnish War)
may become a very serious competitor
if somebody explained to him how to take power: he had plenty of the loyalists in the Army (members of the former 1st Cavalry Army had been holding a lot of the critical positions). Incompetent in pretty much everything (except encyclopedic knowledge of operetta, as was recorded by Schadenko) but a widely promoted figure, much better known (and more "charismatic") than any other Politburo member.
Last but not least Beria - only a candidate to Politburo but a People Commissar of the Internal Affairs and a head of the Soviet espionage system. Actually, during the war Beria was in charge of many areas of the Soviet military effort controlling all areas of the military production, transport, coal, chemical and oil industries, etc. Proved to be quite capable organizer (in his own way).
I'm not seriously considering Andreev, Kaganovich and Mikoyan.
So, Stalin was bad but how any of them would be noticeably better in organizing a war effort?
True. I am imagining such an alternate Soviet army would need a PoD at least in the early 30s, just to scale up the training and education infrastructure.
On the other hand, surely all the people in the armaments factories of OTL also needed to be trained.
Of course. At least in the engineering/design areas the Soviets had been somewhere in the middle of a learning curve (my impression) by 1941 and the same goes for the production area. But in the production re-adjustments had been probably more difficult because they required adoption of the new specifications, retooling, etc. So the main trend during the war was design and production of the simple models of weaponry, easy to produce and easy to learn. As PPSh - stamped parts and extreme ease of assembly/disassembly in the field conditions. But by 1941 they were not there, yet. The same goes for the centralized planning: in the spring of 1941 the munition plants still had been producing the shells for the tanks that were in a process of being decommissioned.
If the Soviets could train the technicians and managers and clerks to produce large numbers of aircraft, submachine guns and tanks for their army in OTL, is there really no possibility to train the NCOs and officers they need if they have a different focus (of course, I am sure the NCOs and officers will be of similar quality to the technicians, managers and clerks in their factories, which is to say, less than ideal)?
They eventually did train the troops during the war when a lot of a ..er,. "practical experience" had been available. Of course, this was extremely costly way but an approach "we'll not look for the cost" had been romanticized even decades after the war. The same goes for the technicians both on the plants and at the front: the equipment was working and reasonably well-served. Flaws in a design cost extra lives but this was not considered a major problem as long as the weapons were reasonably effective (upgrade of T-34 gun had been forced by the German new designs).
If you know any good sources in either English or Russian that shed some light on this area that can be obtained in the Anglosphere, I would be most grateful to hear of them.
