>>393070>what would their victory have changed
Normally I hate to engage in Hypotheticals, considering that each change would lead to massive domino effects etc.
It really does depend on how the victory is achieved. Considering the fact that there were anarchists within the republican government (who also fought against the Durruti faction) it would depend on wether the republic dissolves in a sort of libertarian socialist confederation with minimal state power or it becomes a lot like Aragon. These are important distinctions to make, considering that Aragon was more or less a giant commune with labor vouchers being exchanged.
Sadly, as is the case with a lot of socialist govs, if it was to remain relevant on an international level, it would have to had established more international relations with other states, and that may involve opening trade with neighbouring capitalist countries *or at least doing away with the ideological rivalry of the USSR and China and helping them**. However, given the continued rivalry of the USSR, Yugoslavia and the PRC, it's very likely this rivalry would still continue.
Now in regards to WWII, I do believe that the Anarchists would nonetheless be content on fighting fascism as they had before when the Durruti column drove out Franco during the initial stages of the Spanish Civil War. Considering the fact that anarchists who had fought in the civil war also found themselves as volunteers in the French Resistance, i doubt this international solidarity would cease.
With that in mind, A socialist bloc would likely form within Europe. Considering the fact that Spain neighbours both Portugal and France, the soviets and the anarchists could hypothetically use this to their advantage to pressure these govs into committing an act of revolution. However, let's not be too hasty to suggest that this wouldn't immediately solve the Nazi problem, or the fact that the french still have an empire at this given point in time.
I do nonetheless believe that had the Republic/ Anarchists have won the Civil war, there is a greater chance that we would have seen a more radical future. But let's not mourn about would could have been, and instead focus on what is.
