Italy keeping Lybia has been discussed quite a few times, but what about Eritrea? As per the title, with a POD after Mussolini's rise to power, can Italy keep Eritrea - or part of it - permanently? Or at least longer than it did in OTL?
First thing that comes into my mind is of course Italy keeping neutral in WWII and the Fascist regime staying in power. But could there ever be enough Italian migrants in Eritrea to keep it as part of Italy even if Mussolini still joins the Axis and loses?
