"But you know every false step is a learning experience. And think of this: Communism, as we know it today, I think, started coming apart because of the defeat [of the United States] in Vietnam, because of the battles in Vietnam. And when the Berlin Wall came down, I felt good because, I said, we were a part of that. Those of us who fought in Vietnam are part of that. Maybe I want to feel that way in my heart, I don't know. But I really do. I believe that."
