Classicly

There is no such thing as winning a fight without passion. France went to war apologetically; France fought the war without music, and so France lost. History may eventually record that Britain was saved by the bombs Hitler has rained upon her since the fall of France. Unless they annihilate the British, these bombs will have fulfilled a function Hitler never imagined. He thought they would terrorize the British into surrender; instead the bombs aroused a resistance such as no other population has ever shown, for the prolonged punishment of Britain’s cities has been worse than anything we know of elsewhere, including Belgrade, Warsaw, Rotterdam, Madrid, Barcelona, or Chungking. The British required this experience to awaken them.
