In the fall of 1967, political and military leaders in Washington said the Vietnam War was approaching "the crossover point": More Vietcong soldiers were dying in battle each week than could be recruited. CIA analyst Sam Adams, however, was insisting the good news was an illusion. His estimates of enemy ranks and morale varied wildly from those being released by military intelligence for public consumption, and for use by commanders in the field. Adams' findings indicated the war was unwinnable, and when US leaders failed to acknowledge basic facts, he knew the intelligence was being politicized.

From inside the CIA and then after quitting the agency in 1973, Adams embarked on a one-man crusade to expose the truth. He loved intelligence work, and his enthusiasm for it shines throughout this illuminating memoir. Thanks to Adams, newsman Mike Wallace produced his influential CBS News documentary "The Uncounted Enemy: A Vietnam Deception;" General William Westmoreland was called to account, and his book dramatizes in clear, compelling prose how America's involvement in Southeast Asia became such a tragedy.
