Michael Corleone Explains Popular Uprisings

Michael: [about the unrest in Cuba] We saw a strange thing on our way here. Some rebels were being arrested, and instead of being arrested, one of them pulled the pin on a grenade he had hidden in his jacket. He took himself and the captain of the command with him.
Guest: Ah, the rebels are insane!
Michael: Maybe. But the soldiers are paid to fight; the rebels aren't.
Hyman Roth: What does that tell you?
Michael: They can win.
