“You are in the courtroom of world opinion…. All right, sir, let me ask you one simple question: Do you, Ambassador Zorin, deny that the U. S. S. R. has placed and is placing medium- and intermediate-range missiles and sites in Cuba? Yes or no — don't wait for the translation — yes or no?" [The Soviet representative refuses to answer. ] "You can answer yes or no. You have denied they exist. I want to know if I understood you correctly. I am prepared to wait for my answer until hell freezes over, if that's your decision. And I am also prepared to present the evidence in this room.”

To Soviet U.N. Ambassador Valerian A. Zorin in the United Nations Security Council during the Cuban missile crisis (25 October 1962)
