Walzer looks at how wars are judged. First, by the reason a state has for fighting, and second, by the means they adopt while fighting. He cites Karl von Clausewitz’s On War, which states that the crimes of war are limit-less. Walzer also presents the oft-criticized burning of Atlanta by General Sherman, who claimed that the only side guilty of any crimes of war is the aggressor, while the defender can turn to any means to achieve victory.
