ABSTRACT
Nuclear weapons pose a particularly destructive threat. Prevention of the proliferation and use of nuclear weapons is urgently important to public health. "Horizontal" proliferation refers to nation-states or nonstate entities that do not have, but are acquiring, nuclear weapons or developing the capability and materials for producing them. "Vertical" proliferation refers to nation-states that do possess nuclear weapons and are increasing their stockpiles of these weapons, improving the technical sophistication or reliability of their weapons, or developing new weapons. Because nation-states or other entities that wish to use or threaten to use nuclear weapons need methods for delivering those weapons, proliferation of delivery mechanisms must also be prevented. Controlling proliferation—and ultimately abolishing nuclear weapons—involves national governments, intergovernmental organizations, nongovernmental and professional organizations, and society at large. CONTROLLING THE proliferation of nuclear weapons is one of the major challenges we face as a global society. Given that public health is "what we, as a society, do collectively to ensure the conditions in which people can be healthy,"1(p189) controlling the proliferation of nuclear weapons—and ultimately abolishing them—must be a major global health priority. The threat posed by the proliferation of nuclear weapons has 3 major aspects:
Another important component of the nuclear proliferation issue involves delivery mechanisms. In order to pose a nuclear threat, nations or other entities not only need these weapons but also need missiles or other methods for delivering them. Controlling proliferation of nuclear weapons involves national governments, intergovernmental organizations, and nongovernmental (civil-society) organizations. Governments thus far have attempted to control the proliferation of nuclear weapons through bilateral and multilateral treaties. Intergovernmental bodies, such as the United Nations, the International Atomic Energy Agency, and the International Court of Justice (World Court), have also attempted to control proliferation. Nongovernmental organizations—including professional organizations, such as the Federation of American Scientists, the International Physicians for the Prevention of Nuclear War (IPPNW), and Physicians for Social Responsibility (IPPNWs US affiliate)—have worked to control proliferation through education, information dissemination, and advocacy aimed at governments and governmental organizations. An increasing number of individuals and organizations, including senior US statesmen,2 believe that the only way to address the danger of nuclear weapons is to eliminate them entirely. HISTORICAL EVOLUTION OF NUCLEAR WEAPONS In 1939, Albert Einstein and Leo Szilard warned of developments in Nazi Germany and urged President Franklin D. Roosevelt to begin a research program on nuclear fission for military use.3 The Manhattan Project4 was established in 1941 to develop, produce, and test the first "atomic bombs," and J. Robert Oppenheimer was appointed director. 4,5 On July 16, 1945, the first "atomic bomb" was tested at Alamogordo, NM,4,6 and on August 6 and 9 of the same year, US military aircraft dropped atomic bombs on Hiroshima and Nagasaki, Japan. These bombs, based on nuclear fission, each had an explosive power equivalent to about 20 000 tons (20 kilotons) of TNT. Together, they caused the immediate deaths of approximately 200 000 people and the subsequent deaths of thousands more from blast and thermal injuries, radiation sickness, and malignancies.4,7 Despite opposition by Oppenheimer and other physicists, President Harry Truman ordered development work on bombs based on nuclear fusion—termed "thermonuclear weapons," "hydrogen bombs," or "H-bombs"—in 1951. The work was performed under the direction of Edward Teller, who had urged the development of a fusion weapon while working on the Manhattan Project. The first hydrogen bomb test took place in 1952 at Eniwetok Atoll in the Marshall Islands. The blast had an explosive power equivalent to 10 400 000 tons (10.4 megatons) of TNT—500 times greater than the power of each of the bombs dropped on Hiroshima and Nagasaki. In 1953, the Soviet Union, which had exploded its first fission bomb in 1949, exploded its first fusion bomb.8 In 1961, the Soviet Union detonated a fusion bomb with a yield equivalent to 50 megatons of TNT—over 2000 times greater than the yield of the Hiroshima and Nagasaki bombs and greater than the total destructive power of all the bombs and explosives used in World War II.9,10 The development of these weapons led to the initiation of a worldwide movement for nuclear disarmament.11 After the release of information on the physical effects of thermonuclear weapons and testimony before a Congressional committee about the effects of a possible thermonuclear attack on the United States,12 a group of Boston physicians analyzed the medical consequences of such an attack. Their papers, published in the New England Journal of Medicine,13–15 led in 1962 to the formation of Physicians for Social Responsibility in the United States and in 1980 to the establishment of IPPNW, a worldwide federation of national medical organizations.16 IPPNW received the Nobel Prize for Peace in 1985 in recognition of its work in easing tensions that threatened nuclear war between the United States and the Soviet Union.10,17,18 PROLIFERATION OF NUCLEAR WEAPONS
Horizontal Proliferation In 2003, Iran, which is a member of the NPT, had begun to build a uranium-enrichment facility that could have the capability to produce uranium suitable for use in nuclear weapons.30 In mid-2006, a 6-nation group presented Iran with a set of proposals that called for a halt in uranium enrichment in return for economic and diplomatic incentives and warned that if Iran failed to respond, they would refer the case to the UN Security Council.31 Iran continues to insist that its enrichment plans are purely for civilian use.32 Although analysts believe Iran is still some years away from building nuclear weapons, there is concern that the United States may stage a military attack on Irans nuclear capabilities.33–34
Vertical Proliferation
Acquisition by Individuals or Nonstate Entities
Controlling the Proliferation of Nuclear Weapons Another concern is the possibility of the accidental firing of nuclear missiles in response to false warnings of a nuclear attack. There have been close calls, in which nuclear missiles—many of which are on hair-trigger alert—were being prepared for launch on the basis of faulty reports of incoming missiles.55
Limited Nuclear Test Ban Treaty
Anti-Ballistic Missile Systems Treaty
Treaty on the Non-Proliferation of Nuclear Weapons The NPT went into effect in 1970. In 1992, China and France acceded to it. In 1996, Belarus joined Ukraine and Kazakhstan in removing and transferring to the Russian Federation the last of the remaining former Soviet nuclear weapons located within their territories, and each of these nations has become a party to the NPT, as a non–nuclear-weapon state. The NPT is the most widely-accepted arms control agreement. Cuba, Israel, India, and Pakistan were the only major nations that were not parties to the NPT, until North Korea unilaterally withdrew—a withdrawal that was not recognized by the other 187 parties. India and Pakistan acquired nuclear weapons capability during the 1990s while remaining outside the NPT. Israel is said to retain a significant nuclear weapons capability also outside the NPT. The Bush administration, in 2005, signed an agreement with India to provide assistance in the development of nuclear energy for civilian use. Some analysts contend that the agreement will undermine the NPT, which India has not joined, by providing benefits that are currently reserved for parties to the NPT. The US Congress approved the agreement in late 2006.
International Court of Justice Advisory Opinion
Model Nuclear Weapons Convention The Model Nuclear Weapons Convention would prohibit the development, testing, production, stockpiling, transfer, use, and threat of use of nuclear weapons. States possessing nuclear weapons would be required to destroy their arsenals according to a series of phases over 15 years. The convention would also prohibit the production of weapons-usable fissile material and require delivery vehicles to be destroyed or converted to make them incapable of nuclear uses. The proposed convention outlines a series of 5 phases for the elimination of nuclear weapons: taking nuclear weapons off alert, removing weapons from deployment, removing nuclear warheads from their delivery vehicles, disabling the warheads, removing and disfiguring the plutonium "pits" needed for nuclear weapons and placing the fissile material under international control. In the initial phases, the United States and Russia would be required to make the deepest cuts in their nuclear arsenals.62 THE CURRENT SITUATION
There are approximately 27 000 nuclear warheads worldwide, with an explosive force equivalent to 10 billion tons of TNT—almost 2 tons for every human being (Table 1
The Bush administration is pursuing development of new warheads and a complete renewal of the US nuclear weapons complex infrastructure. The US policy, as elaborated in the National Security Strategy of 2002, undermines the NPT and all arms-control accords by asserting that nuclear weapons and other weapons of mass destruction are only dangerous if in the hands of so-called dangerous people. This policy, therefore, rejects a general nonproliferation standard. The administration has rejected 40 years of bipartisan nonproliferation and arms-control policy in favor of a policy of "counterproliferation," thereby doing serious damage to global efforts to contain the spread of nuclear weapons and move toward their elimination. Its counterproliferation policy and military doctrine allows for the use of nuclear weapons to bring about the nuclear disarmament of an enemy state. The lack of disarmament progress, with nuclear weapons retaining a central role in the defense and security strategies of nuclear-weapon states, has impeded efforts to prevent proliferation and provides an excuse for those who seek to acquire nuclear weapons in contravention of their obligations under the NPT and other international treaties.67,68 At a conference in 2006 organized by IPPNW, Abolition 2000 Europe, IALANA, and the International Peace Bureau—to mark the 10th anniversary of the advisory opinion on nuclear weapons issued by the International Court of Justice—attendees noted the lack of progress toward implementation of the unanimous opinion of the court on the obligation "to pursue in good faith and bring to a conclusion negotiations leading to nuclear disarmament."61 The conference urged that the UN General Assembly, which had together with the World Health Organization requested the advisory opinion from the court in 1996, be asked to return to the court with evidence that little progress had been made in response to the court opinion and with a request for a new advisory opinion that would clarify the meaning of "good faith" negotiations and of bringing them to a conclusion. PUBLIC HEALTH PRACTICE The contributions of public health workers to the prevention of war, and specifically to the control of nuclear proliferation, have taken a wide variety of forms and have been published in a wide variety of venues. Some contributions cover a wide spectrum of public health activities to prevent war.69 Some are specific to nuclear weapons abolition.70–71 Some deal with blocking production of fissionable material that might be used in nuclear weapons.72 Some deal with the perceptions of local residents about the risks of nuclear weapons production.73 Some, the most risky for public health care workers, deal with activities of health workers working in war zones to seek to prevent the continuation of war.74 Overall, the contributions of public health workers to disarmament and peace have been extremely important. In many ways, the dangers posed by the proliferation of nuclear weapons are greater now than ever before. Although these issues may seem distant from the day-to-day practice of public health in a state or local health department, healthcare institution, or academic public health practice environment, there is much that public health workers can do to address the challenges posed by the proliferation of nuclear weapons. Public health workers can educate colleagues, policymakers, and the general public about these issues and disseminate information to them. They can advocate for stronger national and international policies to control the proliferation of nuclear weapons. They can help strengthen public health preparedness in their local areas in the event of a dirty bomb attack. And, through their membership and participation in professional, advocacy, and other nongovernmental organizations, they can play important roles in helping to stop the spread of nuclear weapons and, ultimately, to eliminate these weapons.
