Lee Sandlin said this quote

War ends at the moment when peace permanently wins out. Not when the articles of surrender are signed or the last shot is fired, but when the last shout of a sidewalk battle fades, when the next generation starts to wonder whether the whole thing ever really happened. World War II ended as war always ends -- by trailing off into nothingness and doubt. Its final monument has never been seen by mortal eyes. It's a phantom image at the edge of a rumor: an unmarked grave in the depths of the South American jungle where a weird and decrepit old man, half forgotten by the world, at last entered the lists of oblivion.
