"Artifacts tell us that violent conflict appeared with the very first man. Our early ancestors, having learned to make blades from flint and spears from wood, used these tools not just for hunting, but against their own kind. On every continent, the history of civilization is filled with war, whether driven by scarcity of grain or hunger for gold; compelled by nationalist fervor or religious zeal. Empires have risen and fallen. Peoples have been subjugated and liberated. And at each juncture, innocents have suffered, a countless toll, their names forgotten by time."
