Bill O'Reilly and Martin Dugard take listeners deep inside the global war on terror, which began twenty years ago on September 11, 2001. As the World Trade Center buildings collapsed, the Pentagon burned, and a small group of passengers fought desperately to stop a third plane from completing its deadly flight plan, America went on war footing. Killing The Killers narrates America's intense global war against extremists who planned and executed not only the 9/11 attacks, but hundreds of others in America and around the world, and who eventually destroyed entire nations in their relentless quest for power. With fresh detail and deeply-sourced information, O'Reilly and Dugard create an unstoppable account of the most important war of our era.
