"The tragedy of the diplomatic crisis that preceded the outbreak of the fighting in August 1914, which was to swell into the four-year tragedy of the Great War, is that events successively and progressively overwhelmed the capacity of statesmen and diplomats to control and contain them. Honourable and able men though they were, the servants of the chancelleries and foreign officers of the great powers in the July crisis were bound to the wheel of the written note, the encipherment routine, the telegraph schedule. The potentialities of the telephone, which might have cut across the barriers to communication, seem to have eluded their imaginative powers. The potentialities of radio, available but unused, evaded them altogether. In the event, the states of Europe proceeded, as if in a dead march and a dialogue of the deaf, to the destruction of their continent and its civilisation."
