The military command was fairly solid, although Stalin indeed played an important role there.
It’s hard to assess properly, not in least part because Stalin was in office for almost 20 years when Hitler invaded USSR and plenty could go differently in that timeframe, but I believe USSR would win regardless, first because of other important people in the chain of command, second because allies lended significant help pressuring the Reich on other fronts (and also conducting joint operations with USSR) and third because plenty of people did understand the risks.
Either way, it would be very devastating, even if someone else properly reinforced the Soviet troops ahead of time. Stalin did what he could, given the circumstances.










Fair, but it takes much more than the average home selfhoster’s level of competence.
