This summary book is meant to complement the original. It is not intended to replace the book by Bill O'Reilly and Martin Dugard, #1 bestselling authors. Readers soon find themselves injected into the worldwide war on terror, which started more than two decades ago on September 11, 2001. America went into battle mode as the World Trade Center towers crumbled, the Pentagon burned, and a tiny number of passengers fought frantically to prevent a third jet from carrying out its murderous flight plan. Killing The Killers tells the story of America's long struggle against radicals who plotted and carried out not just the 9/11 atrocities but hundreds of others throughout the globe, finally destroying whole countries in their pursuit for power. Killing The Killers follows the United States' fight against Al Qaeda, ISIS, and the Iranian Revolutionary Guard in Afghanistan, Iraq, Yemen, Syria, Libya, and elsewhere, as well as specific targets of these organizations' most renowned commanders. O'Reilly and Dugard provide an irresistible narrative of our era's most crucial battle with new detail and well-sourced material.
