Summary
The governments driving the new Non-Proliferation and Disarmament Initiative should consider pressing states to clarify the roles they assign to nuclear weapons and exploring a standard of use.

In 1995, the signatories to the Nuclear Non-Proliferation Treaty (NPT) agreed to extend the treaty indefinitely. Reaching this decision was difficult and contentious. As part of the give and take, the nuclear-weapon states agreed to make “systematic and progressive efforts to reduce nuclear weapons globally, with the ultimate goal of eliminating those weapons.” However, by 2000, states recognized the need for a more readily achievable benchmark of progress. So the obligation was added to diminish the “role for nuclear weapons in security policies to minimize the risk that these weapons will ever be used and to facilitate the process of their total elimination.” This benchmark was reaffirmed at the NPT Review Conference in 2010.

And yet, curiously, governments and international experts have not clarified how the “role” of nuclear weapons can be defined and why it matters.

To help fill this void, ten diverse countries have stepped forward to say that they will concentrate on pressing states to further “diminish the role and significance of nuclear weapons in all military and security concepts, doctrines and policies.” Calling themselves the Non-Proliferation and Disarmament Initiative (NPDI), these countries—Australia, Canada, Chile, Germany, Japan, Mexico, the Netherlands, Poland, Turkey, and the United Arab Emirates—seek to restore confidence in the nonproliferation and disarmament bargain that lies at the heart of the global nuclear order. The quality and importance of these governments make it imprudent not to take their perceptions and recommendations seriously.

If the NPDI states are to accomplish their laudable objectives, they will need to blend realism with idealism. Seven of the ten states live under the U.S. nuclear umbrella, and among the seven, there are divergent perceptions of threat from nuclear-armed competitors. Agreeing on where to put the threshold for potential nuclear use will be difficult. Multinational groups naturally tend to settle for lowest-common-denominator positions. Yet, if the NPDI’s demands are anodyne, the initiative will be dismissed as feckless by much of the world. But if the group reaches too high, it will be ignored by the nuclear-armed states.

Between these polls of ambition and modesty, the NPDI could accomplish much by pressing states to clarify the roles they assign to nuclear weapons today and exploring whether a common standard should be applied based on international law. The NPDI could diminish the status associated with nuclear weapons by mobilizing public opinion against irresponsible nuclear saber-rattling. None of this will be easy. But at a time when the global nuclear order appears in flux and no single state or leader can reinvigorate it, the ten states of the NPDI have much to offer.

What States Say Today

The NPDI is charting new terrain. To evaluate whether states are diminishing the role of nuclear weapons it is necessary to understand what the past and current roles of nuclear weapons are in the policies of nuclear-armed states and their protectorates and to establish standards for measuring whether these roles are being reduced.

One measure of the role of nuclear weapons is the type and scale of threats that nuclear-armed states claim would justify use of nuclear weapons. Where among the rungs of military capability and doctrine does nuclear use figure? For example, states that would use nuclear weapons solely in retaliation to nuclear use by others limit the role of these weapons more than states that rely on first use of nuclear weapons to defeat non-nuclear aggression.

Thus, a state that says, like Pakistan does, that it would use nuclear weapons if Indian conventional forces crossed the international border and broke through Pakistani defenses declares a large and early role for nuclear weapons in its national security doctrine. The development and deployment of battle-ready “tactical” nuclear weapons and short-range missiles confirms it.

President Nicolas Sarkozy declared that France’s “nuclear deterrence protects us from any aggression against our vital interests emanating from a State—wherever it may come from and whatever form it may take. Our vital interests, of course, include the elements that constitute our identity and our existence as a nation-State, as well as the free exercise of our sovereignty.” The vagueness and breadth of this definition of vital interests allows the impression that nuclear weapons may have a place not too far up the rungs of capabilities.

For its part, the U.S. Nuclear Posture Review (NPR) of 2001 declared that U.S. nuclear weapons “provide credible military options to deter a wide range of threats, including WMD and large-scale conventional military force.” The 2010 NPR raised the nuclear threshold somewhat. It declared that

  • “The United States will continue to strengthen conventional capabilities and reduce the role of nuclear weapons in deterring non-nuclear attacks, with the objective of making deterrence of nuclear attack on the United States or our allies and partners the sole purpose of U.S. nuclear weapons.
     
  • The United States would only consider the use of nuclear weapons in extreme circumstances to defend the vital interests of the United States or its allies and partners.
     
  • The United States will not use or threaten to use nuclear weapons against non-nuclear weapons states that are party to the NPT and in compliance with their nuclear non-proliferation obligations.”

In other words, the United States now says that nuclear weapons are necessary to deter only states that possess nuclear weapons or that may be seeking such weapons in violation of their commitments under the NPT. It leaves open for now a narrow window of possibility that the United States could initiate the use of nuclear weapons against those states in extreme circumstances to deter or defeat non-nuclear attacks against U.S. allies and partners, as well as to preempt them from using nuclear weapons.

The Russian Federation, according to its 2010 Military Doctrine, “reserves the right to utilize nuclear weapons in response to the utilization of nuclear and other types of weapons of mass destruction against it and (or) its allies, and also in the event of aggression against the Russian Federation involving the use of conventional weapons when the very existence of the state is under threat.” Meanwhile, the United Kingdom in 2010 declared “that we would only consider using our nuclear weapons in extreme circumstances of self defence, including the defence of our NATO allies, and we remain deliberately ambiguous about precisely when, how and at what scale we would contemplate their use.” (The UK volunteered that “no state currently has both the intent and the capability to threaten the independence or integrity of the UK.”)

China has always insisted that it possesses nuclear weapons to deter others from making nuclear threats to coerce it and that Beijing would not be the first to use nuclear weapons in a conflict. India also has a no-first-use policy. Adversaries may question how faithfully China, India, or any other state would adhere to their declaratory policies in an actual conflict. Thus, analysts look for consistency or inconsistency between declarations and force postures and capabilities. Both China and India today possess relatively small nuclear arsenals deployed in ways more suited for retaliatory second-strike use than for first use.

Israel does not proclaim its possession of nuclear weapons or make threats to use them. It has said elliptically that it “will not be the first to introduce nuclear weapons into the Middle East.” Israel is believed to have nuclear weapons and delivery systems that could operate under a range of contingencies and that none of its neighbors could match.

NATO at its 2012 summit in Chicago declared that “the circumstances in which any use of nuclear weapons might have to be contemplated are extremely rare.” The alliance noted that the United States, the United Kingdom, and France have pledged not to use or threaten to use nuclear weapons against non-nuclear-weapon states that are in compliance with their nonproliferation obligations. NATO also “is resolved to seek a safer world for all and to create the conditions for a world without nuclear weapons.” This declared policy stopped short of affirming the United States’ intention to create conditions wherein the “sole purpose” of nuclear weapons would be to deter nuclear use by others. The gap between the NATO and U.S. policies is interesting insofar as five of the NPDI states are also members of NATO.

Offering a Standard, or At Least Tough Questions

Evidently the nuclear-armed states and their allies differ in the roles they declare for nuclear weapons and in the vagueness of their declarations. Given this variety, what standards might the NPDI and the broader international community use to evaluate whether states are diminishing these roles? The NPDI, perhaps reflecting differences among the group, does not say.

Instead, the NPDI has proceeded cautiously by drafting a reporting form that it may in the future ask nuclear-armed states to fill out. Among other things, the form requests information about the numbers of various types of nuclear weapons and delivery systems a state possesses as well as amounts of fissile materials.

China, Pakistan, India, Israel, and North Korea are unlikely to provide much of this information. They worry that if their adversaries know exactly what they possess, the adversaries might be able to calculate the probabilities of successfully attacking these assets. This would weaken deterrence and/or motivate these states to increase their stockpiles to make them harder to attack.

Thus, the NPDI’s desire for transparency in nuclear inventories may remain unfulfilled, but this need not impede the larger goal of reducing the role of nuclear weapons. (The NPDI request that nuclear-armed states list nuclear disarmament steps they have taken since 1995 should be noncontroversial).

The NPDI draft reporting form is most useful where it asks states to describe “measures taken or in process to diminish the role and significance of nuclear weapons in military and security concepts, doctrines and policies.” This is a good beginning. It is difficult to think of a legitimate reason why states should not answer this question.

At some point, though, the international community would benefit from a standard against which to evaluate the roles that nuclear-armed states and their allies assign to these weapons. Any such standard will be debatable; stimulating such debate is a meaningful objective. The NPDI states may not collectively agree to play such a fomenting role, but the issue is worthy of their consideration.

A Realistic High Standard

It is clear that states have inherent and legal rights to defend themselves. Any government would feel a natural imperative when its existence was threatened to use whatever means it had to end this threat.

The International Court of Justice (ICJ) recognized the tension between this reality and the parallel difficulty of positing realistic circumstances in which the use of nuclear weapons would not violate humanitarian law. In its 1996 advisory opinion on the “Legality of the Threat or Use of Nuclear Weapons,” the court issued a nonbinding judgment, in which the majority concluded that “the threat or use of nuclear weapons would generally be contrary to the rules of international law applicable in armed conflict, particularly the principles and rules of humanitarian law.” However, the court could not “conclude definitively whether the threat or use of nuclear weapons would be lawful or unlawful in an extreme circumstance of self-defense, in which the very survival of a State would be at stake.”

The ICJ formulation is probably the most realistic high standard that could be articulated for defining the role of nuclear weapons. That is, a state should only contemplate using nuclear weapons “in extreme circumstances of self-defense, in which the very survival of a State would be at stake.”

Opinions on the matter of course differ. A number of non-nuclear-weapon states and disarmament activists argue that even the narrow opening the court’s majority left for the potentially legal use of nuclear weapons is too wide. Conversely, the declared policies of at least some nuclear-armed states today indicate that they find too constricting the ICJ’s standard of “extreme circumstance of self-defense, in which the very survival of a State would be at stake.”

The ICJ standard, or any facsimile, would confront the NPDI with dilemmas that at least some of the members may wish to avoid for security reasons, alliance relations, or both. Some of the seven states that rely on extended deterrence from the United States would be reluctant to advocate a policy that the United States would not readily embrace. Yet, if the initiative is not to be disregarded over time, the NPDI will need to do more than ask states to report what their nuclear policies are.

One way of doing more would be for the NPDI (and others) to press nuclear-armed states to adopt the ICJ standard and to adjust their doctrines, policies, and postures accordingly. This would naturally raise the burden of argument for states that contemplate the first use of nuclear weapons. They would have to posit non-nuclear forms of aggression that could threaten their “very survival” or that of their allies, thereby “justifying” first use.

Another, somewhat more reserved course would be for the NPDI to ask nuclear-armed states a series of questions intended to elucidate whether and how they would square their potential use of nuclear weapons with the laws of armed conflict and the norms and principles of humanitarian law. Do the nuclear-armed states acknowledge that the laws of armed conflict and international humanitarian laws apply to potential uses of nuclear weapons? If not, why not? If so, then what level of casualties and destruction would they consider to fall below the threshold of humanitarian law? The NPDI could also ask whether the states see a distinction between the first use of nuclear weapons and retaliatory use when they apply the laws of armed conflict and humanitarian law to potential nuclear conflict. How their deterrence doctrines and arsenals reflect sensitivity to the laws of armed conflict and humanitarian law is also key.

Diminishing Nuclear Status

Another element of the role of nuclear weapons is status. The more status and influence associated with possessing nuclear weapons, the greater the perceived and real disadvantage of not possessing them. Many states note the fact that only nuclear-weapon states hold veto-wielding permanent seats on the UN Security Council. The more status that any one state seeks to derive from enhancing its nuclear arsenal, the greater the temptation of nuclear-armed rivals to match it. As the Chinese arms control expert Li Bin notes, “If the United States keeps using its nuclear arsenal to symbolize its status, a question is why China shouldn’t do the same.”

The members of the NPDI could challenge the status associated with nuclear weapons by speaking out when officials in any nuclear-armed state appear to make direct or veiled references to their nuclear arsenal in order to intimidate rivals or to rally domestic audiences. Nuclear saber-rattling to bolster domestic political standing or intimidate others did not end with the Cold War. Yet, the broad international community may be less inclined today to mobilize moral and political opprobrium when intimidating nuclear gestures are directed at small states or seem confined to regional conflicts. The geographic diversity of the NPDI states gives them useful standing to evince and express an international norm against making even veiled threats of nuclear first use.

The NPDI also could publicly urge that if additional states are given permanent, veto-wielding additions to the UN Security Council they should not be nuclear armed.

Why the Role of Nuclear Weapons Matters

Of course, skeptics, especially in nuclear-armed states, will ask “what is the benefit of reducing the role of nuclear weapons?” The NPDI and its supporters should find no objection in answering this question as concretely as possible.

One answer is that in order to strengthen support for the NPT and its enforcement, non-nuclear-weapon states must feel they are gaining greater equity in an international system that was created primarily by the post–World War II great powers. As developing countries gain greater power in a globalized world they want more equitable relations with the established (nuclear) powers. Reducing the role of nuclear weapons is one way to close the gap between the “haves” and the “have nots.” This, too, may be necessary to gain greater support for strengthening and enforcing nonproliferation rules.

For this argument to be persuasive, however, non-nuclear-armed states must demonstrate in deeds that they are in fact willing to strengthen nonproliferation rules and their enforcement. Pressing holdouts to adopt the Additional Protocols that increase the effectiveness of the International Atomic Energy Agency’s safeguards is one obvious way. So, too, is seeking an agreement at the 2015 NPT Review Conference that any state that withdraws from the NPT while in noncompliance with its safeguards obligations will continue to be held accountable for its prior violations until they are resolved to the satisfaction of the international community.

Another motivation for seeking reduced roles for nuclear weapons is simply that all states, including nuclear-armed states, would rather face fewer and less prominent nuclear threats. The taboo against the first use of nuclear weapons has strengthened with each passing year, but its reinforcement takes work. Demanding that the role of nuclear weapons be diminished is a way to raise the global political costs for anyone who would contemplate using them.

Finally, skeptics may say that it does not really matter what roles states declare for their nuclear weapons. Christopher Ford, a former principal deputy assistant secretary of state, for example, argues that “few real strategists take [declaratory policy] too seriously.” NPDI states and others should respond to this assertion.

They could say that declaratory policy matters because publics and governments in many states, including nuclear-armed states, feel it matters. These feelings affect the willingness of non-nuclear-weapon states to cooperate in strengthening the nonproliferation regime. Again, this argument will be persuasive only to the extent that states are in fact willing to strengthen the nonproliferation regime if nuclear-armed states do reduce the role of nuclear weapons.

NPDI states could also note that what leaders say about the role of their nuclear weapons affects how their militaries and other relevant institutions design their force postures and operational doctrines and plans. In this way, declaratory policy influences the nuclear-armed states’ outlooks and behaviors, which in turn affects the broader international community.

Keeping States “Honest”

Dismissals of the relevance of declaratory policy are often cynical and self-contradictory. For example, when an adversary downplays the profile of the threat it projects, as when China insists it follows a no-first-use policy, American strategists and pundits often brush it off as propaganda. But when an adversary speaks bellicosely, as when Iran’s President Mahmoud Ahmadinejad appears to call for wiping the Zionist entity off the map, the same strategists and pundits take it very seriously.

When some U.S. officials or strategists elicit international alarm by calling for new nuclear weapons to strengthen deterrence, the international concern is sometimes dismissed as an overreaction. For example, many international observers perceived the Bush administration’s 2001 Nuclear Posture Review to have widened the role for U.S. nuclear weapons, giving an incentive for states such as Iran and North Korea to seek nuclear deterrents of their own. This perception was largely unfair, but U.S. officials then dismissed it by asserting that U.S. nuclear policy does not affect the motivations that others might have to acquire nuclear weapons. Yet, many in the U.S. nuclear establishment say that the U.S. should not declare that the “sole purpose” of its nuclear weapons is to deter nuclear attacks by others, because such a declaration would weaken deterrence.

Clearly declarations about the role of nuclear weapons do matter. The issue is that depending on one’s perceptions and policy preferences there is disagreement on what should be communicated, to whom, and what the effects of various communications would be. If the NPDI wants to actually fulfill its laudable aspirations, it will have to engage in this debate in some detail and over a sustained period.

At a time when the pathways to further nuclear reductions and the entry into force of the Comprehensive Nuclear-Test-Ban Treaty appear to be blocked, some states are increasing their arsenals, and the Iran nuclear standoff is unresolved, the NPDI offers a constructive means to reinforce the taboo against the use of nuclear weapons. This would be no small accomplishment. It should be welcomed by nuclear-armed states and non-nuclear-weapon states alike.

    Why would a country like Pakistan even listen to what the likes of George Perkovich has to say, when nukes have done wonders for their policy of terrorism and extortion from under a nuclear umbrella ... ?   
    And why would a country like India would have anything to do with the American nuclear Ayatollahs, that make a living by promoting the security interests of the American security and their allies alone ..... ?

    George you fail to note that President Obama explicitly reserved the right to use nuclear arms in response to the threat of biological attacks. Specifically, the U.S. position held, "Given the catastrophic potential of biological weapons and the rapid pace of bio-technology development, the United States reserves the right to make any adjustment in the assurance that may be warranted by the evolution and proliferation of the biological weapons threat and U.S. capacities to counter that threat." Thus, the U.S. position is not so narrow as you suggest.

      You correctly quote the NPR, but the position is more conditional than you say. That is, today, the US is not threatening nuclear use against threats and states other than those that possess nuclear weapons or are not in compliance with NPT violations. If, in the future, BW threats of a large scale emerge, the US would potentially revise this assurance. That does not seem unreasonable to me or to depart from the assurance as written today.

    Thank you for your paper "Reducing the Role of Nuclear Weapons: What the NPDI Can Do" which I enjoyed reading. It was refreshing to see this grouping of NNWS get attention from someone in Washington as it has been a low profile endeavour till now. This despite the nature of the countries concerned and the substantive character of the group's pronouncements. The fifth Ministerial meeting of the NPDI was held in New York this September and its statement referred to several group actions including the draft reporting form, supporting UN General Assembly action (in light of protracted CD failure) on FMCT, lobbying for the Additional Protocol and developing a series of working papers for the upcoming NPT PrepCom. I see this NPDI effort as reflective of a growing assertiveness on the part of NNWS to advance their NPT-related interests.

    The reduction of the role of nuclear weapons is indeed one of the directions the NPDI is pursuing and I would readily endorse your suggestion that the group continue to press the NWS to take further steps to clarify and restrict the role assigned to nuclear weapons in their policies and to devalue these inhumane arms generally. Where I differ somewhat with your argument is the suggestion that in order to obtain these changes to NWS declaratory policies, the NNWS "must demonstrate in deeds that they are in fact willing to strengthen nonproliferation rules and their enforcement". This strikes me as an unequal trade, a fairer quid pro quo for the NWS altering their declaratory policy on nuclear weapons is for the NNWS to strengthen their declaratory policy on nonproliferation. Gaining political support for further nonproliferation deeds by the NNWS is increasingly seen as contingent on further disarmament deeds by the NWS. That is why, however significant is future work on nuclear declaratory policies, I believe the NPDI and other like minded NNWS will increasingly stress actions that yield tangible arms control and disarmament benefits.

    I think the spring NPT PrepCom will provide more evidence of this trend. Thanks again for continuing to focus Carnegie's talents on these major challenges to the integrity of the global nuclear nonproliferation and disarmament regime.

      Ambassador Meyer makes several important points. Further discussion of them is much needed internationally. It would be welcome and fair, as he suggests, for the NNWS to strengthen their declaratory policy on nonproliferation as NWS alter their policies on nuclear weapons. This would be progress of sorts, and welcome. The more vexing and important issue is the “who goes first” problem in the domain of actions: NNWS understandably want the NWS to take further concrete disarmament steps before they take further steps to strengthen the nonproliferation regime, be it adoption of the Additional Protocol, strengthening the IAEA, and clarifying modalities for withdrawal from the NPT, etc. I can say from recent personal experience that key officials in at least four NWS argue (vehemently in private) that there is no evidence that disarmament steps actually beget action by important NNWS to strengthen the nonproliferation regime. They say that nothing was gained in nonproliferation terms from the New START Treaty and further reductions by the UK in its nuclear arsenal. They argue that only naïfs could now believe that ratification of the CTBT by the US would produce any gains in strengthening the nonproliferation regime. And so on. One way forward could be private discussions among NWS and officials from influential NNWS to explore whether any specific quid pro quos could be agreed. Such a discussion could be hypothetical and therefore non-binding…merely exploratory. For example, if the U.S. and Russia were to agree to a further round of reductions, what benefits would accrue on the nonproliferation side? Or if the U.S. and China ratified the CTBT? As things now are, disarmament advocates merely can make hopeful assertions that good things will follow from further steps, with no evidence that this would in fact be so. It would be valuable to hear what officials from leading states in South America, Africa, and Asia would say on this topic.

    In discussion on nukes there is not a word about countries which could use them as a internal policy instrument - could b against their own citizens, a part of them, or more probably, against neighbour, preseted to countrymen as thread. It is not only a case of China contra India, India contra Pakistan, but for example Iran (shia) contra Saudis (sunnis as a response for killing the First Imam). There is no US policy how to manage such threads. Any written conventions are of no use, manufacture of nukes do not require advanced technology and any country can have them at will. In my opinion thre is a need to global police supervision of nuclear sites thus limiting national sovereignty but in interest of all humans.
