European alliance system with No Italian Unification

Say Italy fails to Unify

How would the European alliance system look like without Italy over the years

Would the Kingdom of two Sicilies be closer to Austria or France
 
I would guesstimate that if Prussia did unify Germany then there’d be a Dual Alliance with Austria. Prussia would prop up Austria in Italy. A Dreikaiserbund may work if Prussian support of Austria in Italy is conditioned on Austrian acquiesce to Russian control of Bulgaria and the Straits.

If Prussia does not unify Germany then maybe you see a Franco-Austrian alliance with Southern Italy falling into a French sphere of influence.
