Bill Bundy was somewhat to the left of his brother politically, and was a spirited opponent of Joseph McCarthy. He was also considered one of the administration's more dovish members on Vietnam, and was an advisor to three presidents. In 1989 he acknowledged the complexity of the presidents' decisionmaking, saying, "In a nutshell, my present feeling is that it was a tragedy waiting to happen, but one made much worse by countless errors along the way, in many of which I had a part."
