On the Decline, Possible Rise of American Empire

The astute reader will have noticed that there is no shortage of books on America’s political and cultural decline. Bruno Maçães, who is in no doubt of America’s decline, sees the potential for its resurgence. The key to the future is American relativism. “We are unlearning old truths, a prelude to learning new ones,” he observes in “History Has Begun.” The book, though flawed by expansive predictions and occasional historical inaccuracies, is a fascinating survey of the decline and possible rise of the American empire. We may still believe in the liberal values that have guided Western politics since 1945, but they are now, Mr. Maçães argues, “true in a different way.”
