2Widely regarded as a classic on the Vietnam War, Decent Interval provides a scathing critique of the CIA's role in and final departure from that conflict. Still the most detailed and respected account of America's final days in Vietnam, the book was written at great risk and ultimately at great sacrifice by an author who believed in the CIA's cause but was disillusioned by the agency's treacherous withdrawal, leaving thousands of Vietnamese allies to the mercy of an angry enemy. A quarter-century later, it remains a riveting and powerful testament to one of the darkest episodes in American history.
