    In the days after 9/11, the CIA tasked Crumpton to organize and lead the Afghanistan campaign. With Crumpton's strategic initiative and bold leadership, from the battlefield to the Oval Office, U.S. and Afghan allies routed al Qaeda and the Taliban in less than ninety days after the Twin Towers fell. At the height of combat against the Taliban in late 2001, there were fewer than five hundred Americans on the ground in Afghanistan, a dynamic blend of CIA and Special Forces. The campaign changed the way America wages war. This book will change the way America views the CIA.The Art of Intelligence draws from the full arc of Crumpton's espionage and covert action exploits to explain what America's spies do and why their service is more valuable than ever. From his early years in Africa, where he recruited and ran sources, from loathsome criminals to heroic warriors; to his liaison assignment at the FBI, the CIA's Counterterrorism Center, the development of the UAV Predator program, and the Afghanistan war; to his later work running all CIA clandestine operations inside the United States, he employs enthralling storytelling to teach important lessons about national security, but also about duty, honor, and love of country.No book like The Art of Intelligence has ever been written-not with Crumpton's unique perspective, in a time when America faced such grave and uncertain risk. It is an epic, sure to be a classic in the annals of espionage and war.

    As the 3rd Reich embarked upon its plan of conquest & genocide, IBM & its subsidiaries helped create enabling technologies, step-by-step, from the identification & cataloging programs of the 30s to the selections of the 40s. Only after Jews were identified--a massively complex task Hitler wanted done immediately--could they be targeted for efficient asset confiscation, ghettoization, deportation, enslaved labor & annihilation. It was a cross-tabulation & organizational challenge so monumental, it called for a computer. Of course, in the 30s no computer existed. But IBM's Hollerith punch card technology did exist. Aided by the company's custom-designed & constantly updated Hollerith systems, Hitler was able to automate the persecution of the Jews.Historians were amazed at the speed & accuracy with which the Nazis were able to identify & locate European Jewry. Until now, the pieces of this puzzle have never been fully assembled. The fact is, IBM technology was used to organize nearly everything in Germany & then Nazi Europe, from the identification of the Jews in censuses, registrations & ancestral tracing programs to the running of railroads & organizing of concentration camp slave labor. IBM & its German subsidiary custom-designed complex solutions, anticipating the Reich's needs. They didn't merely sell the machines & walk away. Instead, IBM leased these machines for high fees & became the sole source of the billions of punch cards needed. IBM & the Holocaust details the carefully crafted corporate collusion with the 3rd Reich, as well as the structured deniability of oral agreements, undated letters & the Geneva intermediaries--all undertaken as the newspapers blazed with accounts of persecution & destruction. Just as compelling is the human drama of one of our century's greatest minds, IBM founder Thomas Watson, who cooperated with the Nazis for the sake of profit. Only with IBM's technologic assistance was Hitler able to achieve the staggering numbers of the Holocaust. Edwin Black has now uncovered one of the last great mysteries of Germany's war against the Jews: how Hitler got the names.

    Starting with Alexander Graham Bell's revolutionary "harmonic telegraph," by the middle of the twentieth century the phone system had grown into something extraordinary, a web of cutting-edge switching machines and human operators that linked together millions of people like never before. But the network had a billion-dollar flaw, and once people discovered it, things would never be the same.Exploding the Phone tells this story in full for the first time. It traces the birth of long-distance communication and the telephone, the rise of AT&T's monopoly, the creation of the sophisticated machines that made it all work, and the discovery of Ma Bell's Achilles' heel. Phil Lapsley expertly weaves together the clandestine underground of "phone phreaks" who turned the network into their electronic playground, the mobsters who exploited its flaws to avoid the feds, the explosion of telephone hacking in the counterculture, and the war between the phreaks, the phone company, and the FBI.The product of extensive original research, Exploding the Phone is a ground-breaking, captivating book.
