So, I want to make this more of a conversational thread than a traditional timeline. I'm thinking that the PoD is to have Leon Trotsky to defeat Josef Stalin for rulership of the Soviet Union after Lenin and what the results of that would be worldwide for the next decades.
A Trotskyist Soviet Union would never give up the Global Revolution. Without the Great Purge, and along with Trotsky's own military prowess, the veteran generals of the Soviet Union would likely spend the early years of Trotsky's reign to be preparing for an invasion of Eastern Europe.
Imagine the invasion beginning in '33 or so. With the Great Depression in full swing, I doubt there would be any material support or military action taken by the Western powers.
What do you think the specifics of the PoD that could put Trotsky on top, the specifics of Trotsky's regime, or that of the invasions might look like? How would this affect the West? How would fascism develop differently (if differently at all)? With Stalinism either subdued or butterflied, how would this change the communist parties and movements across the globe?
I'm going to try to write up a summary of the discussion and the agreed upon events and put it below in this first comment to make it easy for people to get into whatever discussion develops.
There are no poor contributions, if you have something to say, go for it.
