Stalin publicly announcing he'd come (back) to Jesus would likely end up with him getting shot, plus his issues seem to have been there for awhile--apparently he'd been a vindictive jerk in the monastery too.
Stalin publicly doing
anything in 1945 makes it normal & acceptable in the U.S.S.R. The magnates who lived in bowel-trembling terror of Stalinist whimsy, wouldn't
dare move against him. Also this would be a popular move given the prevalence of Christians in the U.S.S.R.
Perhaps Stalin pays more attention to why there was so much (initial) collaboration with the Nazis and realizes that he's oftentimes his own worst enemy?
That way, when the USSR starts winning, there's a lot less assholery on his part.
He did that OTL to an extent.
*Perhaps rather than leaving the Home Army to be massacred in Warsaw (and overtly squashing them elsewhere in Poland), he has his minions contact them and drive a hard bargain--the HA must permit pro-Soviet border adjustments and make other concessions to get his help. That's vindictive in a different way than OTL--postwar the fanatically anti-Communist Home Army and London Poles are going to be, to be perfectly blunt, his bitch.
You underrate just how deluded the London Poles/Home Army were, even Churchill was utterly sick of them by 1944. They wont agree to border adjustment even facing immolation & with the Red Army already occupying the territory in question.
*Preventing the mistreatment of German civilians by Soviet soldiers on the grounds this will make his chunk of Germany harder to govern in the long run? If the Soviets were the ones bringing American spam and putting an end to the bombings, they'd be hated less.
They could be more pro-active, but the Red Army acted largely on it's own initiative in this regard. The general reluctance to reign in Soviet troops was understandable given the circumstances of OTL.
nding the DPs back (OTL the British and Americans sent many of them back and around half were killed and the other half sent to the gulag). If there's a concern they could be an enemy in the future, he could insist they be resettled in South America or South Africa, somewhere far away that they can't cause him problems.
The ones who served in German uniform were traitors & deserved whatever they got. The others well. Which countries would willingly take a massive influx of refugees? Why simply have the Soviets treat civalian DP & POWs better?
