Afghanistan, Iraq, and Endless War

It probably was inevitable, as a matter of how Washington as a whole approaches such things these days, that President Obama would make his decision about keeping 5,500 troops in Afghanistan into 2017. There is too much of an expectation that when internal violence prevails in a country in which the United States has had as much past involvement as it has had in Afghanistan, the United States should have its military forces on the scene to try to do something about it, no matter how dim are the prospects for accomplishing much there.

Things have not always been so. It is a departure for the United States to make a habit out of indefinitely stationing significant numbers of its military personnel amid other people's internal strife. This is not entirely a recent phenomenon; the United States did similar things, for example, in Nicaragua during the first third of the twentieth century and later on a much larger scale in Vietnam. But those instances are rightly regarded as failures, they did not have the makings of a habit, and they were not associated with the sort of political expectations about such things that are as persistent and widespread as those that prevail today.

Perhaps the record of long-term stationing of U.S. forces since World War II in such allied countries as Germany and South Korea has obscured how much of a departure are the sorts of long-term deployments we see today in the Middle East and South Asia. But that earlier stationing of forces was mostly about deterring external aggression, which is a very different business from doing something about internal disorder. In the former, if nothing happens over a long time while U.S. forces are overseas, that might be a mark of success; in the latter, if the status quo—which is a violent status quo—persists, that is definitely a failure.

The costs of stationing forces in allied countries for deterrence purposes are mostly limited to direct monetary costs, except for occasional blips such as local resistance to the Marine base on Okinawa. Inserting forces into internal conflicts, however, entails an assortment of consequences that make for greater and broader costs and risks to the United States and that can make the whole undertaking counterproductive. Those consequences, besides the obvious one of U.S. casualties, include the ill will that time and again in such situations has been incurred by destructive effects, however inadvertent or unintended, of the use of U.S. military force in internal conflicts. They include extremist and terrorist responses stimulated by such ill will. And they include the moral hazard involved in the United States carrying burdens that will have to be borne by locals if a local conflict is ever to be settled.

However logical the decision about retaining U.S. troops in Afghanistan may seem—and in a tactical sense may be—the decision leaves unanswered some important questions of a longer-term and more strategic nature. One is: if the United States has been unable to achieve its goals in Afghanistan with 14 years of direct military involvement, why should one think that additional time there will bring about any different result? A related question is: how much longer will it take to achieve whatever we are trying to achieve? The president said, “I do not support the idea of endless war.” But we are left to wonder what to make of the comment by his secretary of defense, “Is it going to be 5,500 forever? I mean, there I can only say this, that is our best estimate now of what we should plan for and are planning for and budgeting for for 2017.” Secretary Carter has acknowledged but failed to answer an important question.

Yet another strategic question is how Afghanistan figures into the larger picture of U.S. interests and grand strategy. Yes, there has been a lot of violence and instability there lately, but how exactly does that relate to U.S. interests, and interests important enough to warrant incurring the costs of an indefinite U.S. troop presence there? The intervention in Afghanistan in 2001 was a direct response to a major terrorist attack against the United States, and counterterrorism is usually invoked as the main rationale for still being there. But that invocation ignores the large differences between Al-Qaeda's situation in Afghanistan prior to 9/11 and what exists there now, the lack of any uniqueness of Afghanistan as a haven for terrorists, and the fact that havens in faraway places are not one of the more important determinants of terrorist threats to the United States. The transition from a retaliatory counterterrorist operation to a nation-building expedition in Afghanistan has never really been explained and justified.

Much of the instant analysis about President Obama's new decision on troops in Afghanistan has been making reference to one of the more dangerous and misleading notions lingering from the Iraq War, which is that the ending of that U.S. military expedition in 2011 was somehow responsible for messes in Iraq that followed, that the messes would have been prevented by extending the U.S. military presence in Iraq, and that Mr. Obama in effect acknowledged a mistake by later reinserting some U.S. troops there. This theme has long been pushed by political opponents of Mr. Obama and by many of those—an overlapping group—still trying to work off their cognitive dissonance for having promoted the launching of the Iraq War, but the theme has appeared in mainstream media in ways that come close to treating it as an accepted conclusion rather than just an accusation.
