For alternate outcomes to the Russian Revolutions at the end of WW1, it seems the two most popular results are either a UK-analog constitutional monarchy or a democratic republic with the Bolsheviks weakened to insignificance.
But what if instead of the Bolsheviks being essentially eliminated, things were more of a stalemate? The Communist Party ends up merely as one of multiple major parties. They have influence, sometimes even being part of government, but not enough to make the U.S.S.R. happen. Maybe things end up more syndicalist than communist (Not that the USSR was ever truly communist< IMNSHO), because the Communist Party encourages unions to take over and own their employing companies? Maybe even nationalising a few now and then when part of government and then turning them over to the workers?
First, how do we get to that point when going through and coming out of the revolutions?
Second, what happens afterwards?
I know a bunch of the newly independent nations were non-Soviet republics after declaring independence from the dissolving Russian Empire, and then later became SSRs as local Communist parties (LCPs) gained control. Did those LCPs set up an SSR with the original intent of integrating into a/the USSR? Did the local SSRs decide to later join the USSR out of communist loyalty and because they owed Moscow for economic & military support when the LCP took over the government, or most of the population was Russian, anyway?
How much of it was coercion and how much was willing? What is the geographical shape of this Russa, and how does this affect any Russian irredentist policies or actions?
