"Perhaps You Have Forgotten. That’s One Of The Great Problems Of Our Modern World, You Know. Forgetting.

"Perhaps you have forgotten. That’s one of the great problems of our modern world, you know. Forgetting. The victim never forgets. Ask an Irishman what the English did to him in 1920 and he’ll tell you the day of the month and the time and the name of every man they killed. Ask an Iranian what the English did to him in 1953 and he’ll tell you. His child will tell you. His grandchild will tell you. And when he has one, his great-grandchild will tell you too. But ask an Englishman—” He flung up his hands in mock ignorance. “If he ever knew, he has forgotten. ‘Move on!’ you tell us. ‘Move on! Forget what we’ve done to you. Tomorrow’s another day!’ But it isn’t, Mr. Brue.” He still had Brue’s hand. “Tomorrow was created yesterday, you see. That is the point I was making to you. And by the day before yesterday, too. To ignore history is to ignore the wolf at the door.”
