A lot of thoughts about Tom...Also in the other thread, about Tom being a traitor. My oppinion is that Michael never forgave Tom attitude during the Solozzo thing. By that time Tom wanted Santino to make the deal and prevent the war. However, Michael didn't think stuff this way.

So Michael's concern was not that Tom would betray him, but that Tom's way wasn't Michael's way. The Cuba buisiness was a mistake by Michael. Not only he lost a great amount of money being fooled by Roth about the Castro thing, but also made his loyal people (the real Mobs in NY) go against him, or at least get frustrated by him. Perhaps Tom's advice would be not to move so much into Cuba. But Michael was Michael and needed no consigliere.

His stuborness lead the family to the facts of #3 and him to the complete breakdown. I am not against Michael, but the way he treated things show a person not flexible enough to understand that the Mof past would never let him go.
