The Essential Domino: American Politics and Vietnam
A Henry Kissinger has written, public support is "the acid test of a foreign policy." For a President to be successful in maintaining his nation's security he needs to believe, and others need to believe, that he has solid support at home. It was President Johnson's judgment that if the United States permitted the fall of Vietnam to communism, American politics would turn ugly and inward and the world would be a less safe place in which to live. Later, President Nixon would declare: "The right way out of Vietnam is crucial to our changing role in the world, and the peace in the world." In order to gain support for these judgments and the objectives in Vietnam which flowed from them, our Presidents have had to weave together the steel-of-war strategy with the strands of domestic politics.

Neither the Americans nor the Vietnamese communists had good odds for a traditional military victory in Vietnam. Given the mutual will to continue the war and self-imposed American restraint in the use of force, stalemate was the most likely outcome.
This common perception had a critical impact on the strategies of both sides. It meant that the "winner" would be the one whose will to persist gave out first. Hanoi's will, because of the nature of its government, society and economy, and because the North Vietnamese were fighting in and for their country, was firmer by far than Washington's. Washington's will, because of the vagaries of American politics and the widespread dislike of interminable and indeterminate Asian land wars, presented an inviting target. For both sides, then, U.S. domestic politics-public support and opposition to the war-was to be the key stress point.
American public opinion was the essential domino. Our leaders knew it. Hanoi's leaders knew it. Each geared its strategy-both the rhetoric and the conduct of the war-to this fact.

A Question recently posed by a distinguished colleague is central for anyone who earnestly seeks to understand how an entire generation of American political leaders, with the best will in the world, pushed the country onto the slippery slope that led ever downward into the engulfing morass of Indochina. The question is this: "Why did so many intelligent, experienced and humane men in government fail to grasp the immorality of our intervention in Vietnam and the cancerous division it was producing at home, long after this was instinctively evident to their wives and children?"
Whatever else we may say of the dissent to the war in Viet Nam, it has effectively reminded us that we are still a democracy. Some may demur that we did not need to be reminded so noisily, but the fact remains: so many Americans turned from indifference or passive skepticism to outright opposition that the policy had to be changed. There comes a time, in foreign affairs as in domestic policies, when "the people" will be heard.
Among the many traumas inflicted by the nightmare of Vietnam has been the realization-for many Americans the shock of recognition-that foreign and domestic policy have merged into a seamless web of interlocking concerns. It is now almost impossible to identify any issue, condition or interest of national significance which is not affected by international trends and circumstances, and which does not in turn affect some aspect of the foreign policy of the United States. For students of public affairs long concerned with both elements of our national posture this may be a truism which hardly bears repeating. However, I regret to observe that most citizens, including most specialists in foreign or domestic affairs, have not yet adapted their insights and prognostications to this integrated view of the world; nor have those of us in public service been effective in foreseeing and planning to deal with the domestic implications of foreign policies, some of them already now in effect.
