Award-winning Australian intellectual Robert Manne presents an incisive analysis of the historical background and current ideology that motivates ISIS and their quest for domination in the Middle East and beyond.In the ongoing conflict with ISIS, military observers and regional experts have noted that it is just as important to understand its motivating ideology as to win battles on the ground. This book traces the evolution of this ideology from its origins in the prison writings of the revolutionary jihadist Sayyid Qutb, through the thinking of Osama bin Laden and Ayman al-Zawahiri, who planned the 9/11 terrorist attack, to today's incendiary screeds that motivate terrorism via the Internet. Chief among these recent texts are two documents that provide the foundation for ISIS terrorism. One is called The Management of Savagery, essentially a handbook for creating mayhem through acts of violence. The other is the online magazine of horror called Dabiq, which combines theological justifications with ultraviolent means, apocalyptic dreams, and genocidal ambitions. Professor Manne provides close, original, and lucid readings of these important documents. He introduces readers to a strange, cruel, but internally coherent and consistent political ideology, which has now entered the minds of very large numbers of radicalized Muslims in the Middle East, North Africa, and the West.However disturbing and unsettling, this book is essential reading for anyone concerned about terrorist violence.
