Okay, so one of the reasons I know of for Mussolini coming to power (or at least having his 'New Roman Empire' ideas) was the feeling in Italy that they had been cheated post-WWI.
Let's say that for whatever reason Italy is given more territory after the war and more say in European politics (i.e. is seen as more important). Ignoring the fine details, what effects will this have on Italy? Say they get their Dalmatian provinces and bigger chunks of Africa (maybe France even gives them Tunisia, or more of West Africa, perhaps they get part of the ex-German colonial empire), will Benny the Moose still come to power?
If so, or if not, will the Italian brand of 'revanchism' still come about, or will it be more focussed on domestic issues?
