Why do you think robert mcnamara changed his mind about the vietnam war ?

itwould be hard to think of a more controversial figure from the Vietnam War era than Defense Secretary Robert S. McNamara who died this morning. He was the longest-serving defense secretary in the U.S. He was one of the original Whiz Kids, a corporate chieftain and later World Bank president, but his identity is tied inextricably to Vietnam.

in his 1995 memoir of the war, McNamara said he and his senior colleagues were "wrong, terribly wrong" to pursue the war as they did. He acknowledged that he failed to force the military to produce a rigorous justification for its strategy and tactics, misunderstood Asia in general and Vietnam in particular, and kept the war going long after he realized it was futile because he lacked the courage or the ability to turn President Johnson around.

once again McNamara was vilified by critics who said he should have spoken up when it might have made a difference and accused him of salving his conscience with a last-minute conversion. A 2004, Oscar-Award-winning film, "The Fog of War: Eleven Lessons from the Life of Robert S. McNamara," addressed what he learned from the war.

confederacy: supported slavery, believed states should be able to nullify federal laws, supported low tariffs

union: everything else
