Careful with rehashing German canards about the USSR, repeated to their American interlocutors, and which mostly absolved the Wehrmacht of their own mistakes. "We were brilliant, it's just that the Soviet 'asiatic horde' was too numerous and didn't care about casualties". This has been shown to be false in more recent studies, less influenced by Cold War thinking. (For example: Glantz shows the frequent outnumbering of Soviets vs Germans was often due to concentration of force -- the Soviets weakened some sectors to overwhelm Germans in others, which is a sound tactic which the Germans failed to understand or prevent again and again, and who made them claim the Soviets were "a horde").
It's ok to bring attention to American industrial might and their very helpful assistance to the USSR, but it's even better to remember it was the Soviets who defeated Nazi Germany. Especially since this was downplayed for political reasons during the Cold War.
The Soviets killed up to 15 million of their own before the war even started. (This number may be an overestimate because most locales had been required to overreport their own population over the past century, such that when an accurate census was conducted, the new number lacked both those killed and also the overreports.) How many million Ukrainians were deliberately starved before the war? 2 million? 4 million?
Neither Germans nor Soviets saw any reason to bother feeding or sheltering their POWs. Soviet POWs were treated as deserters and sent to the GULag on their return, along with many thousands of Cossacks who had escaped well before the war, and were rounded up and sent back.
We need not doubt that there was a great deal of ineptitude in the Soviet officer corps, which had been mostly exterminated before the war and then repopulated according to purely political criteria. And, we need not doubt extreme disregard for the lives of conscripts, both Soviet and many, many others shanghaied from occupied territory.
None of this is to minimize the heroism of the people sent to fight against the Nazis, subject to attacks both from their own government and from a foreign invader. Fairly early in the war (1940?) the NKVD was ordered to abandon its quota of deserters to be shot from the rear for not advancing eagerly enough.
The "asiatic hordes" is a German-created myth, for example. It was necessary for them, because of their cognitive dissonance that made it difficult to accept being beaten by apparently "racially inferior" enemies. How else could they explain it? Was the enemy outthinking them? Impossible, they were genetically inferior. So it must be that they were simply too many and didn't care about piling bodies and bodies until they won.
Also, the Cold War made it necessary for German officers to show themselves as useful to their new American allies, so that they could provide valuable insight into how to battle the Soviet Union. If they could show themselves to be brilliant, only beaten by an unfair superiority of the enemy hordes, Hitler's meddling, etc, so much the better.
No question that that Soviet strategic thinking got better. Stalin's purges had ensured that. But the casulty nunbers never approached parity, unlike every single other army in any other theater given the supuriority.
Another example I would point out is Stalin's bald face lies to the western allies about his intentions to Berlin. Stalin wanted the glory - and more importantly the political control - of Berlin, and deliberately misled the allies into attacking south rather the risk the allies getting any share of the battle. This for example freed up Wenck's XII Army to to try and break back into Berlin in a effort to build a escape corridor.
On the lines around the factories - I'd point out that quite a few American factories, power stations, research facilities were also torn down and shipped to Russia. Sean McMeekin makes the argument that the balance of power was provided by American and British airplanes, and even tanks. In fact the uranium that help kick start the soviet bomb program was supplied - by America.
On Bagration, the point is fair - but it is nowhere near true or fair to state that "it was the soviets who defeated nazi germany" and to point at horrific soviet casualty numbers as justification. Those casualty numbers that had almost as much to do with Stalin's purges, his decision to clandestinely enable the rearmament of Germany in 1920s and 1930, his own wars of aggression against Poland and Finland and the constant and systemic view of the total worthlessness of soviet and civilian lives. To think otherwise is to buy into the soviet propaganda, now being endlessly trumpeted by our very own dictator in the 21st century - Herr Putin.
Allied victory in World War II was exactly that.
Promoting industrial production is a way of taking away credit from the millions of soldiers who actually went and died using it.
The US did do a fair bit of naval work in the second half. And Russia was always openly appreciative of the Hormel SPAM.
