This volume seems mainly concerned with the Kennedy period to McNamara's tenure and stewardship over Defense. In so far as this Review is concerned that would likely be accurate. There are a couple of critical areas which would be potentially more revealing and maybe worth historical thought.
One is the Feb. 65 North Viet Communist attack on Pleiku air base in Vietnam's Central Highlands. This proved a turning point for US policy under Pres. Johnson concerning any US withdrawal from Vietnam; instead leading to the eventual build up and 'limited' war of the mid to late 60s.
Second area, which may be even more valued is the overall impact of McNamara's reorganization to the Defense Dept. under the management principles and practices related to systems analysis and economic approach to warfare practiced. These two focuses had profound impacts both then and likely to the present historically[though am not as aware of the recent history and practices].
More in depth commentary may follow should this thread continue as having entered into the military environment during these ending days to that Johnson-McNamara era in Defense and military History.

These few thoughts are a second reply on the Review concerning McNamara and his history from this new volume, posted on Hwar.
Need to relate, along with the remarks, an illustrative page from US Senate, US Congress 1968 Hearings where Sec. of State Dean Rusk offered his views, then and historically, concerning Vietnam [and the official purpose], Supplemental Appropriations to existing authority, and considerations about finance for US activities in Vietnam. While Sec. Rusk offers considerable commentary on various features of military events, two pages highlight one concern. 
This author's volume is somewhat out of context and inaccurate, though the focus upon McNamara alone may be part of that reason. In fact, in Sec. Rusk comments in 1968, upon the importance of a teams' efforts to bring success in US policy and history for Vietnam, he specifically notes mistakes are part of that overall history, not just for one person alone. Indeed, the Senate is also noted for its mistakes as well.
A Title to this volume can well be "We Made Mistakes," as the pages in the Hearings Report published, in1968, set down as the History then.
