Robert S. McNamara, Former Defense Secretary, Dies at 93
By TIM WEINER
Mr. McNamara helped lead the U.S. into the Vietnam war and spent the rest of his life wrestling with its moral consequences.

The last half of the sentence says it for me. He was not tried as a criminal although by our current standards people may feel he should have been. However, he did suffer severely for his actions. IMO, more so than had he been tried and convicted.
