George Perkovich and James Acton, who have recently and rightfully positioned themselves at the forefront of the new nuclear abolitionists, have a piece in the most recent Bulletin that rebuts certain caricatures of the mature disarmament position. The strongest thread that comes out of the piece is this: ‘as long as other states have nuclear weapons, the United States should maintain a credible nuclear deterrent. Period.’ Noting that ‘nuclear disarmament isn’t an end in itself; it’s a means to enhanced national and global security,’ they argue that the United States should not ‘give them up until the threats that require them have ceased.’ The authors are to be commended for taking an holistic and pragmatic view to nuclear disarmament; if we are to abolish nuclear weapons, it will probably have to be through these means. To be certain, this is the only argument that will command any sort of following among those of influence in the United States.
But is it right? I’m less certain of that. For one, this op-ed, and the longer report from which it derives, seems to make security a prerequisite for disarmament—which, as we have said, is meant to be a means to security. If disarmament cannot demand its intended effect as prerequisite, it must be a cautious starting point by itself.
Beyond the critical point, there are two ways to go about making the argument that Perkovich and Acton are being unnecessarily cautious. The first is to assert that in any endeavor, some country must lead and leadership entails costs. This is a typical solution to collective action problems taught in first-year undergraduate courses. The United States, for example, incurred enormous costs in lives and finances to lead what was intended to be a global war on terror. The costs of leadership with respect to nuclear disarmament would be assessed in terms of increased risk in the event of war or surprise attacks from the remaining nuclear states, or perhaps an increased inability to successfully deter the opponents of our allies. The same moral holds here as they do in our intro courses: the hegemon is uniquely well-positioned to incur these costs, in this case because of a favorable geostrategic position and our overwhelming preponderance in conventional deterrence. By leading the way, we could prove that the costs are not great and can be tolerated; the more states that join in the process, the lower the costs become.
While I think this argument could very well be decisive, I think it is not the right one. I think it is more accurate to say there are so few costs to unilateral disarmament as to make the previous reflections irrelevant. Conventional arms can deter at least as well as nuclear arms, given the unlikelihood of nuclear retaliation even in response to a nuclear attack. Furthermore, the risk of nuclear surprise attack is vanishingly small: China is perhaps the only adversarial country with the capacity to attack us with a nuclear weapon; despite the discussion this scenario receives, it really should be too farfetched to contemplate.
Pavel Podvig asked in the Bulletin recently: what if North Korea were the only nuclear state? He concluded: it would probably be a more comfortable one in which they are the ninth. The strategies of the most powerful states in confronting North Korea would change not at all and so it would suffer not at all: ‘nuclear weapons add nothing to existing nuclear weapon states’…abilities…’ to confront proliferators.
The obverse argument is this: what if the United States was the first modern post-nuclear state? Probably nothing negative of consequence, and perhaps enormous good. Note that the arguments above are not positive ones about the good of unilateral disarmament. That post comes tomorrow (perhaps).
For now let me end where Perkovich & Acton do: what next? If the United States were to pursue unilateral disarmament, the first step would be to signal our intentions to our allies and attempt to gain supporters. (There are recent indications that the United Kingdom would be particularly amenable to taking that step.) Then, declare our intentions and a timetable to coincide with a buildup of conventional arms in the DMZ and other difficult spots. At the same time, offer to put in place a collective security system by which the United States and its allies underwrites the security of all disarming states from attack. Futhermore, establish an international consortium to provide low enriched uranium for nuclear power plants under the same model that URENCO does currently, and subsidize its production to make costs for nuclear fuel appreciably cheaper than parochial secret programs could produce.
The United States is the only country that can make clear in no uncertain terms that nuclear weapons are the implements of a past that humanity wishes to transcend, and that nuclear states are barbarous, backward states. It should.
