McNamara alone was primarily responsible for the inauguration of firebombing Japanese cities. It got to a point when McNamara believes that if the United States would have lost the war then he could have
been considered war criminals by the way he as an individual was acting.
Out of all the 11 lessons that Robert McNamara talks about in his documentary I have to conclude that lesson 11 is the most important. The 11th lesson is “you can not change human nature”, I feel as though it sums up the other lessons perfectly making it, in my opinion, the most significant.
The way McNamara starts explaining this lesson was by broadly stating that we all make mistakes which are human nature. Robert McNamara gives the example that he has never met an honest military commander that did not think that at some point they had made a mistake that may have saved hundreds, thousands, maybe even ten thousand live, not only military soldiers but also civilian lives.
You can use the 11th lesson as a way of explaining the other 10. Although this lesson has a sour look at the war stating that no matter what happens you cannot change the way people look and ask toward thing and each other which explains why we will never fully eliminate war.
From what Robert states you can conclude that no matter how much we try rather it is having maximum efficiency (lesson 4) or if we empathize with the enemy (lesson 1 ) we will never be able to fully comprehend all the thing that makeup war which is why the documentary is called “Fog of War”.
