I was going to add, before the connection went down on me yesterday at the library, that the next logical move would be for Spanish Morocco. IIRC this is separated by mountains from the South-Central area that was under French administration, and would probably require naval aerial cover, or if not at least some sort of naval element as I expect there would need to be landings from the sea. This however is an encroachment on Franco's Spain and Spain would throw everything at its defence. OTL the Anglo-Americans went from Morocco for Algiers but they didn't have a hostile Straits to contend with, and I don't think cutting across the desert and mountains looks that realistic, but I wouldn't know for sure.
