Following World War I, air power promised a revolutionary transformation of war, and Italian General Giulio Douhet (1869-1930) was its first prophet.

After the carnage of the First World War, strategists throughout Europe sought to devise new strategies and technologies that would prevent a repetition of the drawn-out trench warfare on the Western Front. Air power would be harnessed to this aim, and Douhet opined that “the purpose of an Independent air force is to inflict upon the enemy the greatest possible damage in the shortest possible time.” Only that this time the victims of such air attacks would be mainly civilians, but Douhet – and for that matter, JFC Fuller, Liddell Hart and others – expected such a war to be much shorter. They would be horribly mistaken, as the subsequent world war proved.
