"Wars make history seem deceptively simple. They provide clear turning points, easy distinctions.: before and after, winner and loser, right and wrong. True history, the past, is not like that. It isn't flat or linear. It has no outline. It is slippery, like liquid; infinite and unknowable, like space. And it is changeable: just when you think you see a pattern, perspective shifts, an alternate version is proffered, a long-forgotten memory resurfaces."
