(Years later, when McNamara had turned against the war, he talked with John Vann, the lieutenant colonel who had left the Army in protest of the Harkins policies, and the one who had shown statistically how badly the war was going. McNamara asked Vann why he had been misinformed, and Vann bluntly told him it was his own fault. He should have insisted on his own itinerary. He should have traveled without accompanying brass, and he should have taken some time to find out who the better-informed people were and learned how to talk to them.)
