Book excerpt: This book analyzes the complex causes and effects of the September 11, 2001, terrorist attacks both domestically and internationally, and examines the subsequent wars in Afghanistan and Iraq. The first decade of the 21st century witnessed a watershed of political, economic, diplomatic, and military change as a direct result of the events of September 11, 2001. Through narrative chapters, a chronology of events, biographical sketches of principal players, and annotated primary documents, author Tom Lansford documents the domestic impact of the terrorist attacks that stunned the world as well as the subsequent "war on terror" and the invasions and occupations of Afghanistan and Iraq. 9/11 and the Wars in Afghanistan and Iraq: A Chronology and Reference Guide explores the origins and aftermath of the September 11, 2001, terrorist attacks in both the domestic and international contexts. It addresses the rise of global terrorism and the concurrent histories of Afghanistan, Iraq, and the broader Middle East, as well as the interaction of the United States with the region. Events, trends, groups, and individual players are examined as part of the broader historical context, allowing readers to see the connections between these various elements.
