A very interesting post!

I was never convinced that Michael had plans of not surviving in Cuba and am not after reading some of the arguments here. Michael was like his father in always planning and thinking like his enemy thought. But I do agree that he assumed some tremendous risk away from the safety of the Tahoe compound. I also agree that Tahoe was no longer safe for Michael with a traitor in their midst.

Right after Fredo revealed himself to be the traitor in Havana, did Michael have a backup to his bodyguard? I cannot recall a backup. When Michael gives the bodyguard the order to kill Roth, Michael is left completely alone (as far as I can remember) in Havana. I know that he had a driver and plane ready for his departure, but it seemed as if Michael left himself open to being killed in Cuba on New Year's Eve.
