After Danny Greene war the Cleveland family was seriously damaged,after the real stand up guyslike Sinito was implicate in the attempt to kill the city mayor,joe gallo was tapped by the FBI when was openly speaking of family rackets,and Carmen Zagaria that was running a 15 milions a year drug ring flipped and blamed Angelo Lonardo that facing 50 y for drug traffick decide to flip.
So in the middle 1980s the Cleveland family, I dont think that had the men to try to take Youngstown from the LaRoccas.
