The shift from breaking morale to dismantling industrial capacity
In short: Before World War II, the theory of aerial warfare suggested that bombing civilians would cause a psychological collapse, forcing a government to surrender. However, as technology advanced, the objective shifted from breaking spirits to destroying the physical infrastructure—specifically the homes of workers—to paralyze a nation's industrial output.
The concept of 'carpet bombing'—or saturation bombing—aims to inflict complete destruction across a wide geographic area using unguided explosives. While it gained notoriety during World War II, its roots lie in inter-war theories. Military experts like Douhet proposed that high-explosive bombs could cause enough devastation to break civilian morale. This led to the 1922–23 Hague Rules of Air Warfare, which sought to ban deliberate attacks on civilians, though these rules were never ratified by any nation.
As the war progressed, the strategy evolved from 'obliteration bombing' of cities to a more calculated industrial destruction. British Bomber Command, for instance, realized that factory buildings were often more resilient than the housing of the people who worked in them. By targeting residential areas, they aimed to create significant workforce absenteeism, thereby crippling production. This shift was formalized in the 1942 area bombing directive, moving the definition of 'morale' from a psychological state to a measurable reduction in industrial capacity.
The scale of this destruction was unprecedented. In the Pacific, a nine-month campaign against Japanese cities resulted in over 300,000 civilian deaths. In the Korean War, the United States dropped 635,000 tons of bombs—more than the entire Pacific War—destroying 85 percent of North Korea's buildings. Today, carpet bombing of areas with high concentrations of protected civilians is recognized as a war crime under international humanitarian law.
