Choices in War:

McNamara makes the statement that the fog of war is all the complexities of war which can never be fully understood by men. He is correct in a sense. Nobody at the time was able to fully understand the Vietnam War or why it occur ed. Even those that thought they understood the people realize they do not, as evidenced by Trip to Hanoi.
When we look back on the war today, even now we do not comprehend fully what lead to the conflict and why it was necessary. In a historical context, however, even now we cannot look back and say with clarity that if we had not gone into Vietnam, everything would have turned out fine. Domino theory was never disproved and never can be at this point, but it is a far better thing that it did not occur than had we risked not creating a war with the Vietnamese and it had. The greatest crime, is that our officials seem to have learned nothing from the recent past and thrust us into a war with Iraq for reasons even less understandable and seemingly meaningless than Vietnam.
