Pugwash Conferences on Science and World Affairs Nuclear non proliferation and disarmament
In fact, up to now we have not had any use for nuclear weapons in war for two basic reasons. The first reason is that the leadership of the two nuclear superpowers and of the smaller nuclear states behaved as rational decision makers as far as the control of nuclear weapons, and the decision not to initiate the use of such weapons, was concerned. In others words, deterrence worked. The second reason is that, contrary to the expectations of the early nuclear age, most nations remained non-nuclear (in other words proliferation was contained). The nuclear stability which we enjoyed in the last half century should be seen in a significant way as the result of good luck, since the possession of nuclear weapons does not automatically make leaders into rational decision makers, nor are non-nuclear states bound to indefinitely refrain from the acquisition of nuclear weapons. The basic document which helped contain the spread of nuclear weapons is the NPT [Non Proliferation Treaty] of 1968, which is normally referred to as the cornerstone of nuclear stability. The NPT distinguishes its parties between Nuclear Weapon States (NWS) [States who made a nuclear test before 1967] and all the other states that, in order to be a member of the NPT, are classified as Non Nuclear Weapon States (NNWS). The treaty has basically three legs:
The Cold War ended with a significant effort in the direction of nuclear disarmament. Between the second half of the 1980’s and the beginning of the 1990’s, the US and Russia dramatically reduced the size of their arsenals. Moreover, for some time around the end of the Cold War no non-nuclear state decided to acquire nuclear weapons, leaving the set of countries possessing nuclear weapons unchanged, namely the permanent five members of the U.N. Security Council and unofficially Israel. The Chernobyl accident in 1986 induced a gloomy picture of nuclear civilian activity, and for some time interest in this type of energy dropped worldwide, as did interest in proliferation problems associated with the nuclear fuel cycle and the spread of nuclear energy technology. The NPT itself was extended indefinitely in 1995, contributing to what seemed to be a bright perspective for nuclear non proliferation and disarmament. But after the mid-1990’s, the condition of three legs of the NPT began a significant shift. First, Russia and the US basically froze their disarmament agenda, with the last signed treaty leaving some 1700-2200 deployed strategic weapons per side (but only as of 2012) and an unspecified number of tactical, as well as retiredbut not destroyed,nuclear weapons per side. Moreover, the other (smaller) nuclear powers, France, the UK and China, stayed very clear of the complete nuclear disarmament threshold. In 1998, two new declared (but unofficial from the standpoint of the NPT) nuclear powers arose, namely India and Pakistan. And later, for the first time, one country exited the NPT and made a nuclear test (North Korea). Moreover, some remarkable initiativessuch as the establishment of a treaty prohibiting nuclear tests and hence hindering the development of new types of nuclear weaponsbasically failed to become a reality, thus contributing to the feeling that the era of nuclear disarmament was over. Some basic initiatives (the 13 steps) aimed at reinvigorating nuclear disarmament were discussed and approved at the 2000 NPT Review Conference, but were not even mentioned in the 2005 Review Conference, which ended without any final document. Finally, an interest in civilian nuclear energy returned in various parts of the world. Questions about the possibility of an effective control to prevent covert utilization for military purposes of the civilian technology became more and more relevant; the International Atomic Energy Agency (IAEA) in Vienna elaborated stricter constraints to be applied to countries developing civilian nuclear programs, notably the so-called additional protocol. These stricter constraints have been received with mixed response. Many critical countries (i.e., critical form the viewpoint of proliferation risks) declined to sign the additional protocol. A specific country (Iran) has been under extensive scrutiny and has been accused of developing an indigenous fuel cycle with the undeclared purpose of taking steps forward in the direction of building nuclear weapons. In article 6 of the NPT, explicit mention is made not only to nuclear disarmament as a final goal, but also to the pursuing of negotiation leading to an early cessation of the arms race [among nuclear powers], as an intermediate step. The prevailing idea has been that, in a substantive sense, the arms race ended with the end of the cold war. Now we are seeing more and more signs of a trend going in the opposite direction. We can say that there are worrisome signs of the unraveling of the arms control regime as we know it. The cessation of the ABM treaty, the threat, by the Russian side, of the withdrawal from the INF (Intermediate Nuclear Forces) Treaty as a response both to the new propose deployments of missile defense systems in Europe and to the increased intermediate range missile capabilities in many Asian countries, presents a gloomy picture of the status of the arms control regime. It is thus clear why the NPT is seen more and more as being in a critical condition, and why many observers believe that the battle against proliferation is not going well, to put it mildly. Let us be clear: no country supports nuclear proliferation in general. Countries may decide that they need to possess nuclear weapons, but no government is buying the argument that “more is better” when speaking about nuclear weapon states. The statement that a large web of nuclear weapon states deterring each other may be a more stable configuration than the present one, is only an argument used by some political scientists (such as Waltz) to gain notoriety by denying an obvious wisdom. Where countries differ is in the strategy for enforcing non proliferation, and in their individual perceptions of the threat posed by different cases of proliferation. Countries may decide that they want to acquire nuclear weapons for two basic reasons:
The NPT up to now had done a remarkable job in inducing countries to refrain from the acquisition of nuclear weapons by addressing, albeit in an imperfect way, both of the motivations above. The principle of non-proliferation in the NPT helps in creating an environment partially free from nuclear threats, while the principle of disarmament aims at decreasing both the relevance of nuclear weapons and the prestige associated to their possession. The NPT, as is well known, discriminates between haves and have-nots. This discrimination was meant to be temporary, as it has always been understood that the only way to move towards a stable equilibrium was to resolve the distinction between haves and have-nots by eliminating nuclear weapons, namely by making them illegal (as in the case of chemical and biological weapons). Progressing towards such stability is tantamount to having a manifest, unequivocal and sustained progress in nuclear disarmament. While the time scale is uncertain, with the lack of any steady progress in nuclear disarmament we are now seeing very worrisome signs of crisis in the NPT. If, when and how the NPT might seriously crack and possibly collapse is of course not clear, but much depends on how the international community will react to the present difficulties of the non proliferation regime. One of the most notable problems facing the NPT is that some nuclear weapons states, most notably the United States, as well as come other countries have developed a strategy wherein, while paying formal tribute to the role of the NPT, in fact sidetrack it. Their fight against nuclear proliferation takes then a more unilateral approach and includes the following points:
Let us discuss some of the problems and concerns raised by the strategy associated with the above points.
In order to discuss a future reduction of nuclear risks, it is perhaps useful to go back to some of the special features of the NPT. The more unilateralist approach, described before, has created more problems than results, and has significantly eroded the large consensus about the general non proliferation regime. As we said before, the NPT was born as an agreement between states having a very different vision of the world. In the NPT, the “imperialistic” US cooperated with the “evil empire” (USSR) in keeping proliferation under control and, for some time, in dramatically reducing the nuclear arsenals. Different visions of the world did not impede the NPT from working. This should be true even now when the states antagonistic to the US are not as powerful as was the USSR, but may still in general be unlikely to yield to repression. In order to be credible, the three basic legs of the NPT should be honestly respected. Disarmament should not be disconnected from non-proliferation, and assistance in the development of nuclear energy should be given without undue restrictions or discriminations. But in order to improve the collective security in nuclear affairs, there is an urgent need to revisit the entire system of safeguards and constraints on the production of fissile materials. The additional protocol itself (not yet adopted by a sufficiently large number of states) is probably not enough, and more stringent international control on the production of fissile material should be established. New ideas along these lines have been put forward relatively recently by the IAEA, but more ideas are needed. IAEA membership could easily become universal, as even countries outside the NPT are members of the IAEA. There is moreover no objective reason why all countries which are members of the IAEA should not be induced to sign and ratify the additional protocol and other possibly more stringent measures, without exception. The issue of addressing alleged violations of non-proliferation rules will come out as it has recently. Dialogue may be very difficult at times, but can go a long way, and should be the principal instrument for resolving disputes. If even a difficult case like North Korea has been put on a totally different track through dialogue and perseverance, many other cases could presumably be solved by a persistent effort towards dialogue. The effectiveness of sanctions depends on many factors; long-term large-scale sanctions, for example, are generally less effective, as countries tend to adjust to a prolonged sanction regime, and the resulting isolation fosters nationalistic attitudes and cuts off the political/economic leadership from the international arena. Moreover, authoritarian regimes tend to be strengthened by isolation and, if there is a determination to build nuclear weapons or WMD, this determination can be strengthened. Military force has recently been used against countries suspected of violating the non proliferation rules. Leaving aside for a moment the important issue of the legitimacy of these actions, the results have been altogether a dramatic failure. In general terms, it may be true that some military actions slow down the construction of nuclear weapons (or WMDs) by destroying some specific infrastructure, but then what comes next? If, after the destruction of some specific nuclear infrastructure, the country is able to restart the program, then nothing has been “gained”, except possibly some time. And if military pressure on that country goes well beyond the destruction of nuclear plants, then recent history shows that the end result may be a situation of total chaos, where instability may spread and create an intractable problem. To regain consensus for (and credibility of) the NPT and the non proliferation regime, it is really essential that the agenda for nuclear disarmament is reconsidered, and that some relevant visible steps are taken by the nuclear power states. It is in our collective interest that the non proliferation regime be seen as the result of a choice of the entire international community and not as an imposition of some specific more powerful states. In fact, a different attitude should be taken by nuclear power states. What follows here is a list of reasonable, visible steps that could be taken by the nuclear powers to support the credibility of the NPT, by carrying on their obligation under art. VI and more generally steps that could reinvigorate nuclear disarmament.
