RONALD REAGAN, “EVIL EMPIRE SPEECH” (8 MARCH 1983)

I, a number of years ago, I heard a young father, a very prominent young man in the entertainment world, addressing a tremendous gathering in California. It was during the time of the cold war, and communism and our own way of life were very much on people’s minds. And he was speaking to that subject. And suddenly, though, I heard him saying, “I love my little girls more than anything–” And I said to myself, “Oh, no, don’t. You can’t — don’t say that.” But I had underestimated him. He went on: I would rather see my little girls die now; still believing in God, than have them grow up under communism and one day die no longer believing in God. [Applause]
