War had become nothing more than slaughtering soldiers from a safe distance. When this failed to produce victory, civilians too became targeted for annihilation. It took more than a century, two world wars and the invention of the ultimate weapon, the atomic bomb, before the impact of this change started to become fully realized: war had become 'total war'. Warfare in the twentieth century is now an industry. It is bureaucratized, to the extent that its main decisions are being taken anonymously and committed to paper by people far removed from the actual killing zones.
