Since the mid-1990s, the Defense Department has been legally required to review its strategy and force structure every four years, producing what’s called the Quadrennial Defense Review.

The result has been a series of vacuous documents that commingle vague, unsubstantiated claims about great historical shifts underway (think Tom Friedman but without the empirical rigor) with threat inflation. There is no evidence that these documents have produced much beyond wasted time and effort.

Naturally, the Department of Homeland Security decided to produce a quadrennial homeland security review, which is underway. Last week, ForeignPolicy.com reported that the State Department will get in on the act with a Quadrennial Diplomacy and Development Review.  Apparently grand strategy documents have great allure to policy-makers. So it’s worth reflecting on why the QDR has failed.

I say it’s because strategy is overrated. The idea is that government is a scientific enterprise where smart people get together, figure out the wisest course, and then marshal their bureaucracies to the new objectives. The trouble with this view is that government is political; it is about competing bureaucratic interests or ideologies trying to impose their preferences on each other.  Strategy documents have no inherent power over these forces.

In practice, because the military services participate in the QDR’s production, it is an output of the politics it is supposed to guide, a logroll that justifies existing realities. The services all employ manpower to defend their prerogatives. Consultants get hired. A great fuss occurs. Compromise language carries the day, and the thing winds up vapidly endorsing the existing force structure and programs.

A better way to go would for the Office of the Secretary of Defense to use strategy documents to give its views official heft; one more way to impose their preferences on the rest of the Pentagon. That argues for civilian authorship, not service inclusion. Of course, this method is only as good as OSD’s ideas.

The next QDR is due this year. The document will likely endorse the Secretary Gates’ desire to make the military better suited to counterinsurgency, which is OK, and overstate our ability to succeed in these wars, which is not.

The owner of the document is the Undersecretary of Defense for Policy, Michelle Flournoy, who previously founded the Center for New American Security, which has, in its brief life, exhibited great enthusiasm for counterinsurgency campaigns or US military-led nation-building.

Flournoy and a co-author just published a kind of preview of the QDR in Proceedings, the Naval Institute’s magazine. The article not encouraging. It cites the disastrous vehicle of Cold War threat inflation, NSC-68, as an example to emulate. Unsurprisingly it buys into the trendy idea that future US wars will be hybrid wars, mixing conventional and unconventional tactics as Hezbollah did in 2006 in Lebanon. It takes the conventional position that the United States has to police global commons (space, cyberspace, airspace and sea lanes), to protect the “international system.” This apparently means that free trade requires US military hegemony, a common claim with a hazy causal logic. The article makes the curious argument that because the commons are a public good, other nations have “powerful incentives” to help the United States police them. I am all for burden sharing, but this misunderstands the meaning of public goods, which are notoriously underprovided. Powerful incentives encourage free-riding, not mutual aide.

Worst of all, the article buys into the idea that the United States needs to fix failed states, which is a recipe for empire.

The good news is that there is time to fix all this. Maybe the Pentagon will embrace restraint. You never know.
