Jim Sciutto is an anchor and chief national security correspondent for CNN, reporting and providing analysis on all aspects of U.S. national security, including foreign policy, the military, terrorism, and the intelligence community. In "The Shadow War: Inside Russia's and China's Secret Operations to Defeat America," he provides a revealing and at times disturbing guide to this new international conflict that has become the greatest threat to America's national security. Sciutto, a verteran journalist and former diplomat, sends an urgent dispatch from the front lines of this conflict. America, he warns, is in the crosshairs as longstanding adversaries Russia and China fight an unfamiliar type of clandestine warfare, which senior offcials identify as the nation's most pressing security threat facing us today. Their endgame: to defeat the U.S. without a new Pearl Harbor.
