A possibility no one considers is that Gambino was lying about the Bonnano plan because he had an alliance with Lucchese so who is threat to him wanting top spot? Everyone is gonna dismiss this but look at facts. Bonnano who only wanted guys from his part of Sicily made is gonna go to Columbo to do it? The same Columbo who was known to associate with Gambino prior but had no alligence to Bonnano. Who here believes Mag or Bonnano would be allowed to live if they had really hatched a plan to kill Carlo and Tommy? With connections Bonnano had in Sicily it doesn't make sense. I've said this a million times Galante was loyal to Bonnano and the h proves it. Bonnano set the whole fucking thing up and I am a believe they consulted him not because he had power anymore (he realized he was better of in AZ collecting checks) but because they (Dellacroce and Co) gave him ultimatum Galante was gonna be hit reguardless they wanted to give Joe the chance to work with them instead of against. It's not a coincidence that Dellacroce's closest underlings start getting indicted for h few years later. (Ruggerios and Gottis). The trail of h tells the story.
