Kaplan probes the inner corridors of the National Security Agency, the beyond-top-secret cyber units in the Pentagon, the "information warfare" squads of the military services, and the national security debates in the White House, to tell this never-before-told story of the officers, policymakers, scientists, and spies who devised this new form of warfare and who have been planning--and (more often than people know) fighting--these wars for decades. From the 1991 Gulf War to conflicts in Haiti, Serbia, Syria, the former Soviet republics, Iraq, and Iran, where cyber warfare played a significant role, Dark Territory chronicles, in fascinating detail, a little-known past that shines an unsettling light on our future.
