Query: Dereliction of Duty

Robert S. McNamara desperately wants to redeem himself on Vietnam before the "Grim Reaper" appears. I am amazed that so many people rated this documentary so high. While it may be a good artistic production, had someone else asked tougher questions, McNamara would not have been able to go unchallenged.For all who think for a moment that RSM was candid and factual throughout this documentary interview, please read "Dereliction of Duty: Johnson, McNamara, the Joint Chiefs, and the Lies That Led to Vietnam, by H.R. McMaster. This book sets the record straight.
