“There had been a deep and unsubtle optimism among Americans. The Great Depression and Pearl Harbor created a different sensibility that suspected that prosperity and security were an illusion, with disaster lurking behind them. There was a fear that everything could suddenly go wrong, horribly so, and that people who simply accepted peace and prosperity at face value were naïve. The two shocks created a dark sense of foreboding that undergirds American society to this day.” – George Friedman, “World War II and the Origins of American Unease”
