What if, after 1871, Austria-Hungary allies with France and Russia against Germany, Italy, Britain, and the Ottoman Empire? This wouldn't be as irrational as it looks since in the event of victory in a major war Austria-Hungary could conquer lucrative territories at both Germany's (Silesia) and Italy's (Venetia and Lombardy/Milan) expense. I think that France and Russia would love to have an ally like A-H, which in turn would motivate Germany to ally with Italy, Britain, and the Ottomans.
How do you see this playing out long-term and would the Ottoman Empire be the most likely long-term casus belli here?
