Vincent Mancini: Don Lucchesi, you are a man of finance and politics. These things I don't understand.
Don Lucchesi: You understand guns?
Vincent Mancini: Yes.
Don Lucchesi: Finance is a gun. Politics is knowing when to pull the trigger.

Vincent Mancini: [in the helicopter] I'd like to take Joey Zasa up in one of these and drop him.
Michael Corleone: Joey Zasa is nothing. He's a small-time enforcer. He bluffs, threats, but nothing. You can see him coming a mile away.
Vincent Mancini: We should kill him before he kills ...
Michael Corleone: No! Never hate your enemies. It affects your judgment.

Joey Zasa: [during a meeting in Atlantic City] I say to all of you, I have been treated this day, with no respect. I've earned you all money. I've made you rich, and I asked for little. Good. You will not give, I'll take! As for Don, Corleone, well he makes it, very clear to me today, that he is my enemy. You must choose between us.
