Finally caught up with this TL and it's as glorious as ever. I'm eagerly awaiting more grinding tank and artillery battles in France and the Franco-British counterattack. War of machines anyone?
That's the Anglo-French plan. The Germans are trying to fight that war, but they're chronically short of the industrial resources they need to do so, while the Entente have both their own resources and those of the US. Right now the two sides are broadly in balance, but this isn't going to remain for long - the industrial balance is rapidly tipping away from the Germans.
Later on instead of simply killing the good officers he relegated them to insignificant military functions and posts where they could not plot against him, but where they could be used again as the situation requires.
Yes. I can't see him learning that particular lesson ITTL - in OTL it took a long series of catastrophes for him to understand it, here the Soviet Union is doing very nicely indeed and their only reverse to date is failing to grab Bukovina from the Romanians
The problem in this scenario it's that Stalin will never learn that lesson ITTl (and others btw like the fact that he is not a military genius) due the fact that Barbarossa will not happen and the various problem of the Red Army due to his purge will not really emerge, sure there were reform after the winter war but Stalin modus operandi needed some existential menace like the Nazi horde to be changed...otherwise we will have some periodic purge that even if not big as the first will be not all that good for morale and professionalism.
Ummm... sorta-kinda. Stalin wasn't totally addicted to purges so far as I can see, and as I understand it from other purges in other societies they tend to burn themselves out over time anyway. You also can't assume that the army will always be the target of any purges - the power of the General Secretary of the CPSU rested on the three pillars of the Party, KGB and Army - if you want to purge any one you need the support of the others. So it might well have happened that a purge of the Party or KGB would instead have followed, rather than more bloodletting in the army.
Stalin as any dictator don't need an efficient army only something that look efficient and scary even because he don't really care about the overall loss; in OTL Uncle Joe found himself the proud owner of one of the most powerfull and competent army in the world...but only with a lot of trials and errors and due to fighting an enemy hellbent on the total annihilation of the URSS and his population without this incentive well, why change?
Remember that leadership is only one part of having an effective army - size and equipment also count, and the Red Army is getting lots of nice kit and not suffering the huge losses of OTL.
- Joseph Stalin will probably live some years more, sure he was a workhaloic that drink and smoke too much, still commanding the Soviet Union for 4 years in the most brutal war ever fought took his tool (and augment the consumption of alchool), after all even the other leaders had seen their health deteriorating and honestly even a couple of months more can have consequence (see the 'Doctor's Plot').
Then again, look at how he died - fishy at least. We'll never know if he was murdered, but it was certainly a possibility (and he was paranoid about exactly that for years) - and critically when the German invasion happened the Politburo knew they were dead without him. If there isn't an invasion, that uniting factor that kept him in unquestioned power isn't there - so he might well face some serious plots (and note that historically purges have often ultimately consumed those who initiated them, in one way or another).
Without the 'Great Patriotic War' Stalin and communist legacy will be much but much more tainted; hell even here the biggest (and sometime only) justification over Stalin industrialization plan was: Without it the Nazi had won. No Barbarossa and what we have: Famine, Purge, forced relocation, etc. etc....better not forget that the Nazi, before they showed their true color (basically 5 second after their arrive) were well received by the local population
And remember how Khrushchev described Stalin at the twentieth party congress? In OTL that was pretty controversial because of Stalin's place as the saviour of the Soviet Union during the Great Patriotic War - without the war, he's much easier to dismiss as an aberration and not a true communist.
Regarding the URSS after the war, well for first all the 'soft' power she had in OTL here is not existent, no big communist in Italy or other part of West Europe, no years of propaganda in the west in their favor, more difficult time in supporting the anti-colonial movement, no aura of awe and invincibility due to having beaten the nazi; instead we have a nation who's seen as aggressive as Germany (Finland, Poland, Romania and the Baltic...for now) and that had supported the Hitler regime with material vital to their war effort so except for the real true believer the soviet union will not have much external support. This can have consequence regarding the number of people willing to pass information to Moscow and while the URSS can obtain, more or less, the same result without it...it cut time and cost having that kind of information, not counting that any official tech transfer happened in OTL here well...i doubt that will exist, sure the deal with the German help, but in the end is all technology that come in Soviet hand even in OTL.
Counterbalancing that, they aren't being faced by American troops in Europe either, or a NATO that comprises pretty much all of the Europe they don't control. Instead you're looking at some sort of Anglo-French alliance, with some others and with a somewhat remote US that is also deeply anti-Soviet but unwilling to enter into alliances. So in absolute terms their soft power is weaker, but so is that of their opposition - and their economy/military potential is vastly greater than OTL.
Second, his strategic situation is different, gone are the start point in East Europe, here it will be more probably just OTL Poland and Slovackia, instead hostile nation directly border the motherland and in the north there is an armed and not really friendly (I will not put too much 'importance' over Swedish traditionally neutrality, it become real ideologically during the 60's, till now it was more due to purely pragmatic consideration and OTL demonstrated that they were not above secret alliance in case real trouble arise), so while they rightly be considered a powerfull menace and a great power in their own, the level of fear for the red menace will be lower than OTL (expecially if China don't go full Red).
Not so sure about that - the fear will start earlier (the Soviets were never "on our side" but always allied to the Nazis), and they don't have the OTL domination of Eastern Europe to compare it to. We're still in a world where Operation Pike was seriously considered, rather than one where Stalin is "Uncle Joe".
In OTL USSR the Red Army by mid 1941 was in the midst of yet another major reorganisation as armour and mobile units were concentrateded in Armoured Corps - much inspired by the German successes in the OTL campaign in France.
Well, a reorganisation is quite likely but the lessons will be different. I'd say they'll be concentrating on the need for all arms to work together, and on the requirement for a lot of artillery (something that fits well in with Russian doctrine going back a very long time!). You're also likely to see the emergence of the Motor-Rifle division very much earlier - they won't have missed the fact that a large number of surplus Red Army trucks were enough to enable the Germans to sustain an offensive that they would have been unable to a year earlier.
This will not be an army wheer you can repeatedly encircle men by the hundreds of thousands but OTOH it will not be capable of rushing quickly forward into central Europe. It will roll slowly forward like a huge steamroller and if you want to stop it you need a better steamroller.
That depends when - I'd suggest that motorisation is likely to be a high priority, but the sheer size of the army means that this will happen slowly. The war may well be over by the time this process is complete.
Right now he can dictate the trade terms to the Germans, and see his perceived imperialist enemies in the West batter themselves to utter exhaustion while Soviet Union grows stronger in peacetime conditions. There seems to be little need or perceived benefits from rocking the boat by escalating the war, when it is in Soviet interests to keep it going as long as possible.
True right now - but if Germany looks like collapsing I could see him grabbing the rump of Poland and installing a puppet regime. Manchuria is another potential target, if things go badly for Japan - he was certainly an opportunist and there are plenty of potential land grabs out there for him.
