Rod Lyon<\/a> and Malcolm Davis<\/a> superbly articulate the inherent risk of declaratory policy\u2014just because you limit yourself with regard to nuclear weapons doesn\u2019t mean that your adversaries will benevolently respond in-kind. I agree that it may be unsound categorically to rule out nuclear first use in absolutely all circumstances. One of the benefits of a multilateral treaty prohibiting low-yield nuclear weapons over sole purpose is that it raises the nuclear threshold without setting an inflexible condition on nuclear use.<\/p>\n I\u2019ll try to address the specific questions posed by Rod with regard to Baltic and China. First, how does making it clear to Putin that the United States would not contemplate initiating a nuclear conflict to defend the Baltic states enhance Lithuania\u2019s security, even if an unlikely prospect?<\/p>\n The answer turns on a philosophical point. There are some who believe (and I\u2019m not suggesting Rod or Malcolm are in this category) that questioning nuclear deterrence weakens it. I don\u2019t. Nuclear deterrence must stand or fall on credibility and nothing else. If questioning the credibility of nuclear use in certain cases makes actual use less likely, chances are that any security benefit was illusory to begin with. That doesn\u2019t mean the United States should declare redlines (or make sole-purpose declarations), but clarity about when nuclear use is more or less credible helps avoid catastrophic miscalculations and focuses attention on what provides a real security dividend.<\/p>\n In the case of Lithuania specifically, since the United States knows that it\u2019s not going to use nuclear weapons to defend it, and since the Russians know this too, the only people who don\u2019t know are the Lithuanians. What would really provide credible assurance to Lithuania is a much larger deployment of US and NATO troops on Lithuanian soil to deter or defeat a conventional Russian attack. It certainly wouldn\u2019t do Lithuania any favours were those assets to be withheld on the basis of some vague and incredible nuclear assurance.<\/p>\n With regard to the US\u2013China scenario, Rod appears to make both our cases. Yes, China is presently modernising and expanding its nuclear forces, which is precisely what is to be expected given America\u2019s first strike nuclear posture and the proliferation of ballistic missile defences. I agree with Rod that this hinders any move towards sole purpose, and just to be clear I\u2019m advocating multilateral, not unilateral, action on nuclear arms control. But if America reflexively doubles-down on nuclear deterrence without any nuclear arms-control strategy whatsoever then I want to know how America intends to halt nuclear proliferation when, as is foreseeable, China ends up with a nuclear arsenal of comparable size to its own.<\/p>\n Of course, Rod is absolutely correct to say that China\u2019s neighbours are currently more preoccupied with China\u2019s conventional arms build-up. The inconvenient truth is this: there\u2019s no simple answer to China\u2019s conventional military expansion, but we should do all we can proactively to mitigate its risks. If that strategy fails, as well it may, it will be tragic for us and the world\u2014but an overly-aggressive US nuclear posture will do nothing to prevent that, and potentially much to hasten it.<\/p>\n
