Nuclear proliferation has been a nightmare scenario since the end of World War II. The thought of nuclear annihilation was a constant focusing mechanism during the Cold War. However, it appeared to be a manageable issue when the only two countries with such weapons were the United States and the Soviet Union. With more and more countries obtaining nuclear weapons, or threatening to obtain nuclear weapons, the worry that such proliferation may get out of control, and, more seriously, that such weapons might get into the hands of extremist groups bent on violence, posed a frightening possibility.
The genie is out of the bottle. Involuntary non-proliferation is not possible. Should a state (or non-state actor for that matter) want to develop a nuclear weapon, there is little that can be done forcibly to stop it. Therefore, another avenue needs to be found. On the surface this seems impossible, which may explain the calls for military action to destroy the potential nuclear weapons program in Iran. However, recent surprising “victories” in the nuclear non-proliferation struggle may provide some insight into future policy.
The avenues of non-proliferation are these: (1) eliminate the ability of potential proliferators to obtain nuclear technology, (2) destroy (voluntarily or involuntarily) nuclear technology when found, (3) and convince those with nuclear weapons (or those who might want them) to stop their search. As implied by the question, the first two are problematic at best and most likely impossible.
Treaties to limit proliferation have appeared to work to some extent, but rely on voluntary actions. Indeed, most of the countries who have signed the nuclear non-proliferation treaty have little realistic ability to ever achieve nuclear technology in the first place, so it would certainly be in their best interests to eliminate proliferation. However, since the development of nuclear technology is essentially an open science, it is not difficult for any well funded organization to obtain the necessary information and technological equipment. It is not surprising that advanced, modern states like South Africa and Israel were able to build nuclear weapons, but the fact that Pakistan could is reason for pause. If they can develop a nuclear weapon, little can stop anyone from doing so. Indeed, now we see North Korea with at least one and Iran apparently well on the way to developing a weapons program.
The destruction of nuclear weapons or the locations where they are being developed is also limited in efficacy. There is essentially no way to achieve perfect assurance that one knows exactly where the weapons are, that if one did attack that all were actually destroyed, and that retaliation of such an attack might be a nuclear counterattack (Turner, 1999, 2000).
Several writers have offered a view that proliferation of nuclear weapons might actually create a safer world (Waltz, 1981; Weltman, 1980; Mearsheimer, 1990). These scholars, principally neo-realists, argue that “nuclear weapons, amplify and thereby render inviolable the constraints upon untoward behaviour that the condition of anarchy alone engenders (Woods, 2002).” As a result of this strengthening of the system, the international system will stabilize and, within this structure, a “nuclear peace” will ensue. The view of these early proponents of “proliferation optimism” has been lately termed “paleo-optimism” and has been subjected to much criticism. Central among the critics is Peter Feaver.
Feaver (1993) divided the world of nuclear proliferation theory into two camps; optimists and pessimists. Additionally, coining the term “paleo-optimists” to label the early theories of Kenneth Waltz (1981), he set the two schools apart and brought the argument into the forefront. Feaver believes that Karl (1996-1997) and Seng (1997) were able to demonstrate that paleo-optimism (Sagan &Waltz, 1995) has been overtaken by a “new consensus about the determinants of nuclear behavior.” He sees civil-military pathologies existent in various states that undermine command and control of nuclear weapons, thereby keeping them dangerous and unpredictable even with policies that limit their use. A small state that might see itself as a potential victim of a preventive war, may well drive it to, first, obtain nuclear weapons to provide a certain amount of safety, and, second, permit it to adopt (or at least allow) unsafe control and operational practices. Such unsafe practices will likely yield a more unpredictable and therefore dangerous world.
One option presented in some quarters is for the present nuclear powers, beginning with the United States, to eliminate all nuclear weapons, at least all but a few, as a first sign of good intentions. While on the surface this might seem like opening the door to enemies, writers such as Stansfield Turner have argued that only a few nuclear weapons are sufficient to hold the world hostage. Additionally, to induce the political and military leaders that such a move is not dangerous to national security, he has suggested that there are conventional alternatives to all missions and targets traditionally reserved for nuclear weapons (Turner, 1999, 2000; Inbody, 2001).
So, if treaties alone are not adequate, it is impossible to eliminate the information leading to the technology, and the destruction of existing nuclear weapons is at best problematic, the only solution would seem to be finding a way to convince potential proliferators that possession of a nuclear weapon is not in their best interests. Such voluntary elimination of nuclear weapons and development programs is certainly no easy task, but we have two recent events that may give us some cause for hope.
On 19 December 2003, the Libyan government announced that it would eliminate its nuclear development program and would allow international inspections of its weapon sites. The announcement was the result of secret negations with the United States and the United Kingdom that had begun in March 2003. International Atomic Energy Agency (IAEA) Director Mohamed El Baradei took a team of inspectors to Libya by the end of the year and had unrestricted access to the nuclear development sites.
Recent progress with North Korea on talks to end their nuclear program has also been reason for hope. President Clinton declared in 1993 that North Korea “cannot be allowed to develop a nuclear bomb.” Later declarations by the Defense Department stated that “we will not let the North Koreans become a nuclear power. . . . nuclear weapons in the hands of North Korea is not acceptable.” Clinton’s defense policy concluded that the spread of weapons of mass destruction posed the most direct threat to U.S. post-Cold War security interests (Karl, 1997).
Despite such bellicose verbiage, we have come a long ways since then. One country developing nuclear weapons (Libya) has been convinced to stop. Another country that has at exploded on small (probably 1 kiloton) weapon (North Korea) has apparently been induced to negotiate its capability away for other more important considerations. These are hopeful signs.
These two events raise the possibility that under the right circumstances, it is possible to find a state voluntarily giving up nuclear weapons. The question, then, is what is at the root of the nuclear weapon program and how will potential differences in desires be addressed. We must explore why any country wants to (1) obtain and (2) keep a nuclear weapons program.
From a realist point of view, it offers security and power relative to its neighbors. It also seems to offers a certain kind of legitimacy in the world as possessing nuclear weapons makes one part of the “nuclear club” and thereby an entity that cannot be ignored. However, if behind the desire for nuclear weapons is not a desire for domination or expansion, but actually a desire to just be considered a legitimate part of the international community, there may be room for cooperation.
The theories of the offensive and defensive realists seem to offer some insight. Offensive realists such as Mearsheimer, see little room for increasing cooperation. Aggressors can be deterred or defeated, but to think that increasing the information intercourse between states might change the calculus is not within the realm of possibility. Changing incentives may change the discourse, but will likely only yield benefits for one side. Defensive realists, however, see more reason for optimism. Here they agree with neo-liberals that if large transactions can be divided into smaller ones, then transparency can be increased, thereby keeping the gains from cheating and the costs of being cheated low. Under these circumstances mutual cooperation can be made more likely to continue over time (Jervis, 1978; Keohane, 1984; ; Axelrod, 1984; Oye, 1986; Jervis, 1999).
The problem seems to be reducing the issues facing the United States, and presumably other great powers, to figure out how to divide the issues faced by the potential and minor proliferators, and engage in talks to solve them in detail. Solving the details ultimately, albeit slowly, results in a larger, likely more long lasting solution. That does appear to be what has been going on with North Korea. Kim Jong Il may not actually have desired the absolute power that results from nuclear weapons. He may only have wanted security for his state and to sit at the table with the world powers and be taken seriously. If North Korea can be convinced that the United States will permit them to sit at the table and if they can be convinced that it is not in the interests of the United States to attack North Korea, they may well be induced to give up the nuclear program in exchange for security. Kaddafi apparently wanted to ensure that his successor, presumably his son, would be in a situation whereby Libya would not be isolated from the international community. Since the real desire of Kaddafi was to be part of the international arena, isolating that issue from others, i.e., dividing transactions into smaller, more easily devoured bites, it became possible to negotiate a successful result of eliminating nuclear weapons in at least one country.
The specter of nuclear weapons in the hands of extremist groups is frightening. Possession of nuclear weapons by Pakistan and the potential possession by Iran raise fears of transferring the weapons to such groups’ hands, either deliberately or inadvertently. This makes it all the more important to find ways to engage those states that already have nuclear weapons to ensure the safety and security of the weapons in the first place, and to increase the likelihood that the command and control of such weapons are secure and not open to failure or sloppy procedure.
