Query: Mistakes galore.

A candid view of the Vietnam war from the perspective of Robert McNamara, who served as Secretary of Defense during the Kennedy and Johnson administrations. McNamara, along with others, were dubbed "the best and the brightest", but failed miserably in their estimate of the situation in Vietnam and in the execution of the war. McNamara exposes the mistakes that were made. He concluded that 3 critical elements required for success were lacking in Vietnam: a stable government; a stable economy ; and support of the war effort by the Vietnamese people. He finally realized the war effort was futile and departed the Johnson administration. Hopefully the lessons learned from his experience may assist members of government from making similar errors of judgement in the future. This book is well worth reading and lends credence to the cliche "hindsight is always 20/20".
