As Sonny said to Tom “Pop can't do nothin' til he's better†Then necessity because of Sonny's death
Besides Vito upset and angry it was Michael who killed Sollozzo and McCluskey may have believed or
wanting to believe that Sonny with Tom had the business [if Vito still cared!] under control as well as can be, at least on the surface because among others -
- Sollozzo and McCluskey were dead
- Newspapers printing McCluskey being linked with Sollozzo in the drug rackets
- No other killings after Bruno Tattaglia
- things are starting to loosen up
- Fredo going to Las Vegas to learn the casino business under the protection of Don Francesco
Hence I think under the circumstances there was really no need for Vito to be “counseling Sonny and Tom†even if Vito was up to it After all they managed when Vito was in hospital and pulled off Sollozzo and McCluskey's murders
However if Vito was “counseling Sonny and Tom†Vito probably would have advised the same or similar as Tom did to Sonny –
- business especially the Corleone business needs to continue more so than the others because of the Corleones' own overheads
- The Corleones can't afford a stalemate!
- not to go after old pimp Tattaglia
- Let the smoke clear until the Corleones are in a position to 'negotiate'
