The Allied bombing of Axis cities, which killed hundreds of thousands of civilians and made smoking ruins of Dresden, Tokyo and Hiroshima, remains one of the great controversies of WWII; this probing study does the issue full justice. Philosophy professor Grayling (The Meaning of Things
) focuses on Britain's "area bombing" of entire German cities, a strategy adopted initially because bombers couldn't hit smaller sites and then, as attitudes hardened, continued as a deliberate attack on civilian morale. Grayling scrupulously considers the justifications for area bombing—that it would shorten the conflict by destroying Germany's economy and will to resist, that civilian workers were also combatants or that it was simply the rough justice of war—and finds them wanting. British bombing, he contends, did little damage to the German war effort at an unconscionable price in innocent lives, in contrast to American pinpoint bombing of industrial and military targets, which succeeded in paralyzing the German economy with few civilian casualties. (The Americans, he sadly notes, resorted to area bombing in their devastating air campaign against Japan.) Drawing on firsthand accounts by theorists, architects, victims and opponents of area bombing, Grayling situates a lucid analysis of the historical data within a rigorous philosophical framework.
