What is a key advocacy point made by Guilio Douhet regarding warfare?

Guilio Douhet, an influential figure in the development of air power theory, made significant contributions to the understanding of strategic bombardment in warfare. A key advocacy point from his theories is the emphasis on targeting civilian population centers to undermine enemy morale. Douhet believed that breaking the will of the civilian populace would lead to a faster conclusion of conflict, as a demoralized public could pressure their leaders to surrender or negotiate peace. This perspective is rooted in the concept that air power could directly affect the outcome of war by striking at the heart of an adversary's societal fabric, creating psychological rather than just physical impacts. Such a strategy was revolutionary at the time and continues to influence military doctrine today.
