Good suggestion for the future plot of “The Godfather Part IV”.
As for the Godfather IV, that'll be mostly how some guy who buys into the gaming and hospitality industry becomes President then realizes that the mob is quietly helping him fight the globalists who have nearly destroyed all the solid business it took nearly a hundred years for the mob to build.
Once he knows, does coordinate with them or simply pretend he doesn't know and let things play out without his actively trying to help them in return for them helping him.
