Italians are probably best qualified but theere are exceptions. IMO MW is trying to live vicariously through Fausto Dominick “Nick” Geraci, Jr.. On this issue, MW makes race an issue himself. He says he could pass for German or Irish, whatever pass means and that hes fair haired, like MW. He makes him a well educated, street smart guy who looks like MW, and is also a really tough fighter. I dont think Puzo ever put himself in the story.
