Most people typically think of armed conflict in physical terms, involving guns and bombs, ships and planes, tanks and missiles. But today, because of mass communication, war and the effort to prevent it are increasingly dependent on non-physical factors - the capacity to persuade combatants and citizens to engage in violence or avoid it, and the packaging of the information on which decision making is based. This book explores the many ways that mass communication has revolutionized international relations, whether the aim was to make war effectively or to prevent it. Gary Messinger shows that over the last 150 years a succession of breakthroughs in the realm of media has reshaped the making of war and peace. Along with mass newspapers, magazines, books, motion pictures, radio, television, computer software, and tele-communication satellites comes an array of strategies for exploiting these media to control popular beliefs and emotions. Images of war now arrive in many forms and reach billions of people simultaneously. Political and military leaders must react to crowd impulses that sweep around the globe.Nation-states and nongovernmental groups, including terrorists, use mass communication to spread their portrayals of reality. Drawing on a wide range of media products, from books and articles to films and television programs, as well as his own research in the field of propaganda studies, Messinger offers a fresh and comprehensive overview. He skilfully charts the path that has led us to our current situation and suggests where we might go next.
