WASHINGTON – Robert S. McNamara, the brainy Pentagon chief who directed the escalation of the Vietnam War despite private doubts the war was winnable or worth fighting, died Monday at 93.

McNamara revealed his misgivings three decades after the American defeat that some called "McNamara's war."

"We of the Kennedy and Johnson administrations acted according to what we thought were the principles and traditions of our country. But we were wrong. We were terribly wrong," McNamara told The Associated Press in 1995, the year his best-selling memoir appeared.

McNamara died at 5:30 a.m. at his home, his wife Diana told the AP. She said he had been in failing health for some time.

Closely identified with the war's early years, McNamara was a forceful public optimist. He predicted that American intervention would enable the South Vietnamese, despite internal feuds, to stand by themselves "by the end of 1965." The war ground on until 1975, with more than 58,000 U.S. deaths.

his apoloy for war on vietnum sounded not honest.
