Maybe misunderstanding the question: pre-war, Sonny was perceived as the Tattaglias' ally in setting up the drugs operation. If he was assassinated, I think that you would have to assume that the Tattaglias/Sollozzo had targeted the entire Corleone hierarchy, and act accordingly.
Mr mustachepete could you, uh -- amplify your answer a bit? Thanks
