Book excerpt: In this provocative study, Paul Atwood attempts to show Americans that their history is one of constant wars of aggression and imperial expansion. In his long teaching career, Atwood has found that most students know virtually nothing about America's involvement in the wars of the 20th century, let alone those prior to World War I. War and Empire aims to correct this, clearly and persuasively explaining US actions in every major war since the declaration of independence. The book shows that, far from being dragged reluctantly into foreign entanglements, America's leaders have always picked their battles in order to increase its influence and power, with little regard for those killed in the process. This book is an eye-opening introduction to the American way of life for undergraduate students of American history, politics and international relations.
