I repeat what I wrote earlier, just to see if there's a possible idea of this occuring.
Another possible idea: how about either Venice and/or the Knights of St John getting involved? A Maltese acquaintance of mine said that until Mussolini a lot of Maltese considered themselves to be Italian. So what about Malta AND Tunisia being in the same boat, compounded by the fact that the Maltese languageis is a hybrid of Maghreb Arabic and Sicilian, with some English words thrown in and a Latin alphabet?
