"But the most lasting agony of this war was suffered, not by the defeated, but by the victors. For when their passions had cooled, the Americans could not easily disguise from themselves that they had committed murder. They were not at heart a brutal folk, but rather a kindly. They liked to think of the world as a place of innocent pleasure-seeking, and of themselves as the main purveyors of delight. Yet they had been somehow drawn into this fantastic crime; and henceforth and all-pervading sense of collective guilt warped the American mind. They had ever been vainglorious and intolerant; but now these qualities in them became extravagant even to insanity. Both as individuals and collectively, they became increasingly frightened of criticism, increasingly prone to blame and hate, increasingly self-righteous, increasingly hostile to the critical intelligence, increasingly superstitious."
