An absolute doctrine is impossible, for once a doctrine and its articles become dogma, woe to the army which lies enthralled under its spell. - J. F. C. Fuller

In 1919 I was the sole person who saw war in the form it would be; yet saw it only as an acorn and not as an oak.

I believe that, in future warfare, great cities, such as London, will be attacked from the air, and that a fleet of 500 aeroplanes each carrying 500 ten-pound bombs of, let us suppose, mustard gas, might cause 200,000 minor casualties and throw the whole city into panic within half an hour of their arrival. Picture, if you can, what the result will be: London for several days will be one vast raving Bedlam, the hospitals will be stormed, traffic will cease, the homeless will shriek for help, the city will be in pandemonium. What of the government at Westminster? It will be swept away by an avalanche of terror. Then will the enemy dictate his terms, which will be grasped at like a straw by a drowning man. Thus may a war be won in forty-eight hours and the losses of the winning side may be actually nil!
