Well, then go for a POD before 1870.
OK, but in my rendition there are no "Germany" and "Italy" as we know them anyway.
Post 1848, Austria, France and Russia conspire to stymie the unification of Italy and Germany.
There is no Crimean War which was pointless anyway, so no hard feelings between St. Petersburg and Vienna.
With out French help, there is no Italy. But Austria and France take the initiative to create a Confederation (featuring an Austrian satrapy in Lombardy/Venetia under Ferdinand Max) under the Presidency of the Pope and susceptible to their meddling. Sardinia is a sulking member of this union.
In Germany, Prussia is isolated and cannot pull off unification of the German states in the face of the resistance from France, Austria and Russia.
So maybe the alliances that arise later in the 19th century are FAR (France, Austria, Russia) vs. Great Britain in league with Prussia, Sardinia and the nationalists in Italy and Germany.
