" A known fact may be so unbearable that it is habitually pushed aside and not allowed to enter into logical processes, or on the other hand it may enter into every calculation and yet never be admitted as a fact, even in one’s own mind. Every nationalist is haunted by the belief that the past can be altered. He spends part of his time in a fantasy world in which things happen as they should – in which, for example, the Spanish Armada was a success or the Russian Revolution was crushed in 1918 – and he will transfer fragments of this world to the history books whenever possible. Much of the propagandist writing of our time amounts to plain forgery. Material facts are suppressed, dates altered, quotations removed from their context and doctored so as to change their meaning. Events which, it is felt, ought not to have happened are left unmentioned and ultimately denied.fn6 In 1927 Chiang Kai-Shek boiled hundreds of Communists alive, and yet within ten years he had become one of the heroes of the Left. The realignment of world politics had brought him into the anti-Fascist camp, and so it was felt that the boiling of the Communists ‘didn’t count’, or perhaps had not happened. "
