"When I was liberated in 1945, April 11, by the American army, somehow many of us were convinced that at least one lesson will have been learned -- that never again will there be war; that hatred is not an option; that racism is stupid; and the will to conquer other people's minds or territories or aspirations, that will is meaningless. I was so hopeful. Paradoxically, I was so hopeful then. Many of us were, although we had the right to give up on humanity, to give up on culture, to give up on education, to give up on the possibility of living one's life with dignity in a world that has no place for dignity. We rejected that possibility. And we said, "No, we must continue believing in a future, because the world has learned." But again, the world hasn't. Had the world learned, there would have been no Cambodia and no Rwanda and no Darfur and no Bosnia. Will the world ever learn?"
