Is that to say Rome would have eventually become part of Italy on its own ITTL, with Italy gaining Trentino and Dalmatia? Would Nice and Savoy be completely out of the question later on along with both Tunisia and Libya?
Had your response to this
old thread in mind with regard to how ATL could have evolved had Cavour lived longer. Aside from enhancing Italian-American relations by having Garibaldi accept Lincoln's proposal to enlist in the Union Army during the American Civil War and spread some Italian culture in the US much earlier compared to OTL, what additional benefits would there be for this ATL Italy as far as colonies in Central America, South America or Asia, etc are concerned?
The Papal states living on borrowing time is a given, the moment France is uncapable to defend them or retaliate they will be conquered by Italy...if there is not a internal revolution as the place was not very stable.
There is the slight possibility that Cavour can convince the French to make the Pope accept an agreement, but it's hardly a given and it will be need a minor miracle.
Nice and Savoy are up to grab only in a case of Italy joining Germany against the French and even in that case, is more probable that Florence (the capital of Italy at the time) will need to chose between one of the two (my bet is for Nice, if only for Garibaldi lobbying for that)...or for the equivalent of WWI, in such case both are for grab.
In case of much better performance in the A-P war, well Italy will get Trento (in OTL Garibaldi was an inch to conquer the city) or Dalmatia not both and some diplomatic skill will be needed to achieve that.
Tunisia will be target number one for the italian colonial effort due to economic, geographic and historical reason...but this can be also said for France and it will be needed the agreement of the Concert of Europe to anybody snatch it; maybe Italy is more succesfull ITTL due to more stable goverment and lesser isolation but honestly is more probable that the best case scenario will be a gentlemen agreement that if French take Tunisia, Italy will get Libya plus some form of protection for the italian population in Tunisia as OTL
Colonies in America is not in the market, unless some is for sell, more for the fact that the British will not be happy of some new players in the zone (as everybody else); better Italo-American relations can mean a better treatment of the italian immigrants there (even if 10 more years of Cavour can butterfly away the reason of the massive Italian diaspora).
Asia is more doable, especially Papua as only the British disagreement stopped this and North Borneo can be obtained if there is more desire of colonial expansion (Cavour will surely support anyone that had such idea) and more importantly if there are enough funds, even a treaty port in China is very possible
