Assuming Austria makes various reforms to it's military in the run up to war and or the Prussians make some bad mistakes, what is going to happen with Prussia trounced? It's logical to assume they have Silesia and maybe the Rhineland taken away from them and the German Confederation somewhat centralizes further around Austrian power. But the big question is German Nationalism and Unification into a Nation State, do the nationalists go on to push for greater unification of Germany into a truly centralized State? If so, what becomes of Austria's non German territories? If a Gross Gross Deutschland comes about including all of the Austrian Empire's non German lands, or a Gross Deutschland in personal Union with a Kingdom of Hungary and a Kingdom of Galicia comes about, how do the internal politics of GGDL or GDL + Hapsburg Kingdoms in Union and the international alliance politics of Europe play out ? Additionally what becomes of the Prussian lands outside of the German Confederation?
