Book excerpt: Britain yesterday; America today. The reality of being top dog is that everybody hates you. In this provocative book, noted historian and commentator Jeremy Black shows how criticisms of the legacy of the British Empire are, in part, criticisms of the reality of American power today. He emphasizes the prominence of imperial rule in history and in the world today, and the selective way in which certain countries are castigated. Imperial Legacies is a wide-ranging and vigorous assault on political correctness, its language, misuse of the past, and grasping of both present and future.
