The outrageous shutdown of the federal government's operations has multitudinous effects on foreign relations and national security. Some of the effects are easy to see. Others are less discernible or measurable but may over the long term be more important.
Most apparent are the direct effects of work not being done because it takes money that has not been appropriated or would have been done by federal employees who have been laid off. Sometimes this is clearly visible in the form of things such as presidential trips abroad being curtailed. Even this category of consequences, however, goes beyond what is immediately visible and what can easily be counted right away as an opportunity that would otherwise have been seized or a calamity that would otherwise have been avoided. Much of the work of people in the State Department, the Department of Defense, the intelligence community and elsewhere in the government cannot be counted that way even though it is important in contributing to the seizing of opportunities, the avoiding of calamities, and other ways of advancing the national interest. It is work that builds long-term foundations for advancing those interests, maintains preparedness to deal with the unexpected, or contributes to knowledge and information that can be acted upon in the future.
This aspect of what federal personnel do, day-in and day-out, is insufficiently understood. Much public discussion of counterterrorism, for example, is couched in terms of how many terrorist plots have, or have not, been foiled lately. In fact, most of the work of officials in the counterterrorist community does not consist of detecting and foiling ongoing plots. It is nonetheless work that is critical to developing the knowledge of terrorists and terrorist networks that makes possible the preventing or foiling of plots. If the shutdown has a cost in the form of anti-U.S. terrorism, it will less likely be seen in the form of attacks that occur during the shutdown than in ones that take place later.
A more general impact of the shutdown concerns how it may shape the attitudes of foreign governments about dealing with the United States. A concern that commentators already have expressed is that there will be increased reluctance of foreign states to negotiate agreements and commitments with a government whose own house is so out of order. The concern is valid. It represents a cost that may be substantial in the form of lost opportunities for the United States even though it will be hard to prove conclusively a direct connection between the shutdown, attitudes of foreign governments, and a particular missed opportunity. How the shutdown story ends up will affect how much of this type of harm there will be; if the president can confirm the principle of not caving in to disorderly and extortionate houses, this will help the credibility of the United States as a negotiating partner.
Even more general and harder to measure, but ultimately of high importance, are the effects on attitudes not just of foreign governments but of foreign populations, or at least of elites who are sufficiently aware of what is going on in Washington for it to make any difference in their thinking. At stake is the image and standing of the type of political system that the United States—when it is not crippling itself by shutting down its own government—represents. This in turn is important because it affects the political choices foreigners make and the objectives they seek, especially during times of upheaval such as has prevailed in the Middle East for the past three years.
U.S. interests are tied to all this in two basic ways. First, when foreigners choose liberal representative democracy this is good for the United States as a matter both of values and of more policy-specific consequences such as those of which the democratic peace theorists speak. Second, the United States has enjoyed standing as the leading and most powerful exemplar of this form of governance. This is a major ingredient of America's soft power—its attraction for those foreigners who ipso facto are more inclined to associate with it, to emulate it, and to follow its lead.
