In 1962, McNamara supported a plan for mass spraying of the rice fields with herbicides in the Phu Yen mountains to starve the Viet Cong out, a plan that was only stopped when W. Averell Harriman pointed out to Kennedy that the ensuing famine would kill thousands of innocent people.
McNamara's own teenage son, Robert Craig McNamara, was opposed to the war and denounced his father when he came from work every day. McNamara was shocked to discover that the American flag was hanging upside down in his son's bedroom as the younger McNamara told him that he was ashamed of America because of him.
