In a desperate attempt to end the chaos of the war, Kaiser Karl I of Ausria Hungary tried to broker a separate peace agreement with the Entente through his brother-in-law Prince Sixtus of Bourbon-Parma. In otl the negotiations largely fell through because of the Austrian Foreign Minister Czernin's aggressive speech which angered Clemenceau to leak the negotiations to the public. But supposing these negotiations were successful, what would the borders of a surviving Empire look like. How would the other Central Powers react to Austria signing a separate peace deal? What would Europe look like in the aftermath of the War? What sort of political developments would take place within the Empire? How would Austria-Hungary affect WW2 moving forward? Would a precondition for this settlement be a more decisive Caporetto offensive such that the KuK army looks poised to occupy Venetia?
Could Italy go Communist here or perhaps have an earlier Fascist type dictatorship? What would Poland look like? Could it possibly end up as a monarchy and ally with Austria-Hungary to support the Russian Whites or perhaps against a Revanchist Soviet Union? What would the Balkans look like? Instead of Yugoslavia would the Serbians just take Bosnia as part of a Greater Serbian Kingdom?
