In the novel, Moe Green was killed before the Day When Michael Settled All Family Business. The Don was still alive. In fact, the novel strongly implies that the Don gave the order to have Moe killed. After Michael returns from Vegas without an agreement from Moe, he meets with the Don and the caporegimes.. Michael proposes that the Family make Moe "an offer he can't refuse." Tessio says that if Moe wanted to talk to the Don, Michael should have let him. But the Don says, "I've retired. Michael would lose respect if I interfered. And besides, that's a man I'd rather not talk to." Tessio then realizes that Moe Green is a dead man.
As Ricardo said, Cuneo and Stracchi survived the later,post-Don, Michael-ordered massacre that took the lives of Barzini, Tattaglia, Tessio, Fabrizzio and Carlo.
