At the far edge of the world, a remote chain of windswept islands ignited a war that would change everything. In April 1982, Argentina's military junta launched a sudden invasion of the Falkland Islands, sparking a high-stakes international crisis at the height of the Cold War. For British Prime Minister Margaret Thatcher, it was the ultimate test of leadership. Her government was faltering, her popularity collapsing, and few believed Britain could fight and win a war 8,000 miles from home. They were wrong. Edge of the World is a gripping, fast-paced account of the Falklands War, one of the most dramatic and consequential conflicts of the late twentieth century. From the corridors of power in London and Buenos Aires to the icy waters of the South Atlantic, this book brings to life the decisions, risks, and battles that defined a generation. As Argentine leader Leopoldo Galtieri gambled on a swift victory to save his regime, Thatcher made a bold and controversial choice: to strike back. What followed was a brutal air and naval war, the fiercest since World War II, fought under extreme conditions, with the eyes of the world watching. But this is more than a story of war. It is the story of how a single conflict reshaped global politics, strengthened the alliance between Britain and the United States, accelerated the fall of the dictatorship in Argentina, and transformed Thatcher into the "Iron Lady", one of the most powerful and polarizing leaders of the modern age. Drawing on international sources and behind-the-scenes accounts, Edge of the World reveals how three months of conflict altered the course of history, and proved that even in a divided Cold War world, the outcome of a distant war could echo across the globe.
