I have no firm idea of an alternative history scenario, but i would like to look at some interesting alternatives for the Austro-Prussian war - 1866, with anyone interested.
Point A) If the Italians accept the Austrian offer of Venetia in return for neutrality, brokered by Napoleon III. What happens then, does prussia back away from war with Austria. Does Austria win.
Point B) If Austria gains Italian neutrality, and thereby is able to demobilise on the Italian frontier. Bismarck now has no excuse for accusing Austria of insincerity in the, Austro-Prussian disarmament talks brokered by Bavaria. What happens then, is it possible that Bavaria can succeed in it's aim of instituting federal reform. Is it possible that Austria and Prussia are forced to negotiate seriously, a federal german state. What would it look like and what role does Austria play.
