I've been thinking lately about the possibility of a Red Germany (across the Rhine, at least) in the aftermath of WW1 or the Russian invasion of Poland. [1]
There's no guarantee that a Russian-German bloc would hold, anymore than China and the Soviets formed an eternal union. But they would both have (and had) a lot of congruent and complementary interests in OTL. And the reactions in France and the United Kingdom to a Red Bloc spanning from the Rhine to the Pacific would be... amusing.
[1] No, not the victorious Red armies washing their boots in the river; I think it's more likely that the French occupy the Ruhr after the Germans treat a Soviet invasion of Poland as an excuse to retake the Corridor and get clever with reparations, and whoops, now the KPD and hard left of the SPD have risen up during hyperinflation.
