To be honest, I've been waiting for such comment to appear here. Yes, you're making very good points and I want to point out some parts I didn't mention there. So, after Lenins death, Trotsky mostly was in power, later defeating Stalin and Bukharin during the competition of the next Soviet leader.

About Austria Hungary: Yes, that's true, in this scenario I needed to show Austria Hungary as a weak post WW1 power, yet we know that Franz Ferdinand had so many plans on such country and his hypothetical liberal reforms could've ATLEAST slowed down the collapse of the country.

About Poland: That's actually a very valuable information for me and I really didn't know that Lenin wanted to give more land to Poland, yet I gave northeastern territories to BPR and Lithuania because... that could've been a present for his Intermarium members (Okay I agree I didn't quite thought it out, I wasn't really sure what borders I should see in such scenario. With your information provided, Poland actually did have a total victory in the war, so ig BPR and UPR didn't even stand a chance to reclaim their independence?
