Presuming some sort of delaying action and the Germans capture Paris in later 1914, the Russians are still in a handy position to make for a S.Q.A. peace at that point. By May 1 1915 in OTL the Germans had captured only the frontier of Russian Poland and did not make serious headway until later on. Certainly the Germans and AH can now devote many more resources to the East while carving up French interests amongst themselves. I think Russia will negotiate their way out with Poland certainly becoming a CP state, but Finland and the Ukraine are less likely. Yes, the opportunity for a joint venture into Russia is there, but Austria is having internal problems. The war might go into late 1915, with the Gorlice-Tarnow breakthrough perhaps achieving even more as more manpower and supplies spent in OTL Western Front an Italy come into play. Maybe OE joins for a crack at the Caucasian mountain chain, though maybe they sit the war out and try to modernize as they were doing OTL. Either way, unless Berlin and Vienna are willing to push for 3-4 years of extra warfare I think the best scenario you get is a CP Ukraine satellite and then only if Russia holds little/no CP territory with a few significant defeats of its own. Manpower will tell in time, but then war dissatisfaction at home could play out as well depending on the scenario. I also concur with earlier posters in that this war only encourages a future conflict given that far fewer people will be dead here.
