Ira Katznelson seems to like a lot of things about Grand Expectations. I thank him for his words of praise and for giving the book a careful, thoughtful reading. Although he says little about my many specific judgments and interpretations, he helps readers grasp my main themes. As he points out, I argue that Americans between 1945 and the late 1960s developed ever-grander expectations about their capacity to create a better world abroad and a happier society at home.
