“Modern war with its extravagant material factors places an especial importance upon a nation’s economic structure and particularly upon its ‘industrial web.’ A nation may be defeated simply by the interruption of the delicate balance of this complex organization, which is vulnerable to the air arm and directly to neither of the other arms. It is possible that a moral collapse brought about by disturbances in this close-knit web may be sufficient to force an enemy to surrender.” – James Lea Cate and Wesley Frank Craven, “The Army Air Arm Between Two Wars, 1919-39,” The Army Air Forces in World War II
