The greatest accomplishment of Western civilization is arguably the achievement of individual liberty through limits on the power of the state. In the war-torn twentieth century, we rarely hear that one of the main costs of armed conflict is long-term loss of liberty to winners and losers alike. Beyond the obvious and direct costs of dead and wounded soldiers, there is the lifetime struggle of veterans to live with their nightmares and their injuries; the hidden economic costs of inflation, debts, and taxes; and more generally the damages caused to our culture, our morality, and to civilization at large. This second edition represents a large-scale collective effort to pierce the veils of myth and propaganda to reveal the true costs of war, above all, the cost to liberty.
