> but it could have stopped World War II. The Spanish Civil War was definitely a component of WW2 but I don't see how it being resolved could possibly impact WW2 happening - if the Allies won the Spanish Civil war it's pretty unlikely they'd reinstate the democratically elected government anyways due to the red scare - you'd likely have a democratic-ish puppet government. Fascism was also present next-door in Portugal (Salazar) and it didn't really have much impact at all on WW2.
