Even so, we remain convinced that there has been a quiet yet steady breakdown in civilian control of the armed forces over the past 30 years. These problems are more serious and far-reaching than Schake and Feaver describe. The erosion has been incremental and cumulative—a steady process of degradation rather than a single breaking point. It has largely flown under the radar, aided by a lack of public awareness, the military’s extraordinarily high approval ratings, and partisan polarization that discourages meaningful reform.

As both Schake and Feaver note to varying degrees, civilians have played a role in damaging the military’s nonpartisan ethic. The exploitation of military service and symbols by politicians, for instance, continues unabated. In the months since our article was published, there have in fact been new affronts to the military’s neutrality, with some politicians seeking to draw the military into the country’s culture wars. In July, Tom Cotton, a Republican senator from Arkansas, suggested that senior officers’ perspectives on U.S. racial politics should be a litmus test for their promotion to flag rank, saying that he “may start probing nominees” about their views. As long as American politics remain polarized, politicians on both sides of the aisle are unlikely to stop using the military for partisan gain.

Polarization and negative partisanship, moreover, are not confined to elected representatives. These traits are also evident among the American public. Survey research by one of us (Jim Golby) and Feaver has shown a troubling trend: that voters increasingly want the military to take their side in partisan debates. Such divisions mean that even when the military behaves in a nonpartisan fashion, just about any action it takes can be interpreted as partisan. Although we agree with Feaver that civil-military relations would benefit from a renewed focus on civic education, that will probably not be enough to address the problem. For the public to stop viewing the military as a partisan actor, politicians will need to stop treating it as one.
