There are many plusses to this documentary. One of course is to see a different insider’s view of history. Another is we get a feel for what McNamara is really like as a human being instead of a news item. We even get an “If I had it to do all over” scenario.
I was especially interested in the Vietnam era as I was there in 67-68 and at the time did not pay attention to the big picture. It makes you wonder what we will find out about today tomorrow.
Aside from the interesting history and different views of the actual decisions of the time, is that the presentation wand in a more chronological order, instead of a bunch of sound bites pouncing back and forth between different narrators, jumbling the timeline in the process.
This is a good addition to your library and can prove useful for future generations.
