So let's imagine the Republican side wins the Spanish Civil War. They join the Comintern in 1938. WW2 starts in schedule, with Molotov-Ribbentrop, so the Allies are at war with the Axis but not with the Comintern. Does Barbarossa proceed as usual, just with an invasion of Spain too? Does this mean Vichy France formally joins the Axis as Barbarossa begins? How would this alt-WW2 go? Do the Spaniards hold, or are they easily overrun? Is there an Anglo-American landing in Spain? If so, what is the fate of Spain after WW2?
