Ludwig von Mises laments the passing of the Age of Limited Warfare and the coming of Mass Destruction in the Age of Statism and Conquest (1949)
Published in the immediate aftermath of the Second World War, Mises’ magnum opus, Human Action (1949) contained a chapter on "The Economics of War" in which he laments the killing of innocents:
War & Peace
How far we are today from the rules of international law developed in the age of limited warfare! Modern war is merciless, it does not spare pregnant women or infants; it is indiscriminate killing and destroying. It does not respect the rights of neutrals. Millions are killed, enslaved, or expelled from the dwelling places in which their ancestors lived for centuries. Nobody can foretell what will happen in the next chapter of this endless struggle.
