Without the Russian Revolution, some groups do not get the funding they did, but neither do governments set out on witch hunts to kill them off. A part of the reason the Russian Revolution really worked was that it was the first of its kind, and everyone underestimated the Russians. (Then again the Bolshies did get very lucky, and the timing was just right... etc. etc.)
Ah, I wondered if anyone was going to look at it in a logical fashion - ie what happens if there is no Russian Revolution (I am assuming that is what the POD means, rather than it happens but fails)
So, you have a Kerensky-ite Russia, co-operating in some fashion with the workers soviets, remaining in the war but not particuarly effectively...
Supposing that this Russia remains stable enough to remain on a defensive posture until the end of the war, then what end of the war do we actually see ?
There would be withdrawal of German forces from the East, so no Michael Offensive in the West so no collapse in response to that, so probably we are looking at a Spring 1919 Allied offensive after a Winter of shortages, hardship and unrest in the German Empire
Presume the offensive breaks the front and succeeds in breaking through into Germany, then we have an analogy of late 1918 but with harsher conditions and a potentially more angry populace. Also there are no free forces in the East to bring back, so a Leftist revolution might conceivably take root in Berlin ?
