Why do you think relations between presidents and the press deteriorated during the Vietnam War?

On april 30, 1975, when the last helicopter lifted off the roof of the U.S. Embassy in Saigon, the Vietnam War, the most consequential event in American history since World War II, ended in failure. More than 58,000 Americans and as many as 3 million Vietnamese had died in the conflict. America’s illusions of invincibility had been shattered, its moral confidence shaken. The war undermined the country’s faith in its most respected institutions, particularly the military and the presidency. The military eventually recovered. The presidency never has.

It did not happen all at once, this radical diminution of trust. Over more than a decade, the accumulated weight of critical reporting about the war, the publication of the Pentagon Papers in 1971, and the declassification of military and intelligence reports tarnished the office. Nor did the process stop when that last chopper took off. New evidence of hypocrisy has continued to appear, an acidic drip, drip, drip on the image of the presidency. The three men who are most responsible for the war, John F. Kennedy, Lyndon B. Johnson, and Richard Nixon, each made the fateful decision to record their deliberations about it. The tapes they left behind—some of them still newly public, others long obscured by the sheer volume of the material—are extraordinary. They expose the presidents’ secret motives and fears, at once humanizing the men and deepening the disillusionment with the office they held.
