For twenty-five years, in a good many remote odd spots in the world, the United States has been locked in battle; or has been seconding some distant and sometimes dubious friend; or trying, by promising help, to deter the start of the trouble altogether. With so many and such far-flung commitments and no sign of letup, it is only natural that there should be a lively debate about their number and extent and how they fit our capabilities. The frustrations of these 25 years of engagements in remote wars, and not only the present long-drawn-out and uncertain struggle in Viet Nam, encourage a new isolationism.
For twenty-five years, in a good many remote odd spots in the world, the United States has been locked in battle; or has been seconding some distant and sometimes dubious friend; or trying, by promising help, to deter the start of the trouble altogether. With so many and such far-flung commitments and no sign of letup, it is only natural that there should be a lively debate about their number and extent and how they fit our capabilities. The frustrations of these 25 years of engagements in remote wars, and not only the present long-drawn-out and uncertain struggle in Viet Nam, encourage a new isolationism.
The new isolationism differs in many ways from the old. It often fits the desire to turn over to the United Nations problems that we have dealt with mainly on a national basis-all of foreign economic aid, for example, and all or most of the problem of resisting local aggressions against allies or friends. However, the radical nationalism of the old isolationists had itself a good deal in common with the wishful sort of internationalism: both were ways to avoid the uncertainties and strains of dealing with a great many diverse and partially hostile political entities.
Today, sentiment favoring a withdrawal from international to domestic concerns may be based simply on fatigue; or on the familiar but unanalyzed feeling that very distant troubles are remote not simply in miles but in their likelihood of having any effect on us. But aside from a sense that distant troubles are irrelevant, there are more substantial beliefs. One belief (very influential, though usually inexplicit) holds that "the effectiveness of the power radiated from any national center decreases in proportion to the distance involved."[i] As a result, areas near the borders of a great power are dominated by that power. In these spheres ("spheres of influence" have figured prominently if rather ambiguously in recent Senate Hearings), a great power can forcibly exclude distant great challengers. The result is, then, a balance which it is futile to try to upset; and unwise: its persistence is a guardian of vital U.S. as well as opposing national interests.

In today's interconnected world, weak and failed states pose an acute risk to U.S. and global security. Anticipating, averting, and responding to conflict requires more planning and better organization -- precisely the missions of the State Department's new Office of the Coordinator for Reconstruction and Stabilization.
A new history of the United States' pre-September 11 efforts to combat terrorism portrays them as marked by myopia, indecision, and diffidence.
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.
