Koprulu Mustafa Pasha
Gone Fishin'
The greatest thing I like about the Austrian/Hungarian empire is that post 1815, they had their hands in so many geopolitical places they could have become a superpower easy despite so many failed chances beforehand. Which is mind blowing. You have the Italian Question, all of the other non German lands within Austrian-Hungry Empire, the German question, Maxmillian on the Mexican throne, a dying Ottoman Empire, a weak Russian Empire, Japan on the side of the planet and an impartial USA up until 1917. You also have other opportunities like Spain and Greece offering thier thrones and possibility to build the Suez, Panama and Nicaragua canals. The only real fighters are Prussia, France and the UK.
Despite all of this, I think that all these missed opportunities feeds into thier tragedy, decline and eventual destruction to be a puppet of the German Empire. Then you only an idiot (Moltke) to muck up the Schliffen plan and her increasing dependence on Germany increases to the point where the Habsbutgs don’t really run thier own state anymore.
Russia was nowhere weak before 1877. The dying Ottoman thing was considered after 1878 (wrongfully, Ottomans still survived) and got Bosnia for it.
