On May 11 and 13, 1998, India tested five nuclear weapons in the Rajasthan desert. By the end of the month, Pakistan had followed suit, claiming to have detonated six nuclear devices at an underground facility in the Chagai Hills. With these tests, the governments in Islamabad and New Delhi loudly announced to the world community, and especially to each other, that they both held the capability to retaliate with nuclear weapons in response to any attack.

What will be the strategic effects of these nuclear weapons developments? There are many scholars and defense analysts who argue that the spread of nuclear weapons to South Asia will significantly reduce, or even eliminate, the risk of future wars between India and Pakistan. These "proliferation optimists" argue that statesmen and soldiers in Islamabad and New Delhi know that a nuclear exchange in South Asia will create devastating damage and therefore will be deterred from starting any military conflict in which there is a serious possibility of escalation to the use of nuclear weapons. Other scholars and defense analysts, however, argue that nuclear weapons proliferation in India and Pakistan will increase the likelihood of crises, accidents, terrorism and nuclear war. These "proliferation pessimists" do not base their arguments on claims that Indian or Pakistani statesmen are irrational. Instead, these scholars start their analysis by noting that nuclear weapons are controlled by military organizations and civilian bureaucracies, not by states or by statesmen. Organization theory, not just deterrence theory, should therefore be used to understand the problem and predict the future of security in the region.

An updated Atoms for Peace program is needed to help solve problems of national and international security brought about by increased civilian use of nuclear energy.

Coherent and consistent leadership from the United States and other states is essential if the programs needed are to go forward with adequate speed.

The world's governance and enforcement machinery must be updated and strengthened if it is to be equal to the challenges.

Important leverage can be provided if the countries that have or readily could  have nuclear power can reach broad agreement that nuclear terrorism must be prevented. 

In the recent past the issue of covert trade in nuclear material gained public prominence when it was erroneously claimed by British intelligence sources that the former Government of Iraq under Saddam Hussein had tried to obtain uranium from Niger. The far reaching consequences of such assessments for society were clearly demonstrated by U.S. President George W. Bush in his speech on January 28, 2003, using this incorrect information as one of the reasons why terrorists and countries belonging to the "Axis of Evil" posed a potential nuclear threat. In view of the occurrence of such significant errors even in the intelligence community, it is not surprising that information in the media on the topic of illicit trafficking of nuclear material is frequently flawed by errors.

In order to avoid the pitfalls of evaluating important security-related decisions from questionable sources of information, this paper discusses only the most reliable currently available data on illicit trafficking of weapons-usable nuclear material, contained in the Database on Nuclear Smuggling, Theft, and Orphan Radiation Sources.

In The Spread of Nuclear Weapons: A Debate Renewed, professors Waltz and Sagan resume their well-known dialogue concerning nuclear proliferation and the threat of nuclear war. Kenneth Waltz, Senior Research Scholar in the Arnold A. Saltzman Institute of War and Peace Studies at Columbia University, expands on his argument that "more may be better," contending that new nuclear states will use their acquired nuclear capabilities to deter threats and preserve peace. Scott Sagan, the leading proponent of organizational theories in international politics, continues to make the counterpoint that "more will be worse": novice nuclear states lack adequate organizational controls over their new weapons, resulting in a higher risk of either deliberate of accidental nuclear war. Treating issues from the ’long peace’ between the United States and Soviet Union made possible by the nuclear balance of the Cold War to more modern topics such as global terrorism, missile defense, and the Indian-Pakistani conflict, The Spread of Nuclear Weapons: A Debate Renewed is an invaluable addition to any international relations course.

This paper discusses three questions:

1. Could terrorists or others steal nuclear fuel from research rectors, to make either a nuclear weapon or a "dirty bomb," a radiological dispersal device?
2. Could terrorists attack a research reactor with conventional explosives, for example with a truck loaded with such explosives, in order to disperse radioactivity from the fuel of the reactor to an area downwind of the reactor?
3. How do power reactors compare with research reactors as targets of terrorist attacks?

The answer to the first two questions is a qualified yes. In the comparison called for in the third question, the low-enriched uranium in power reactors is unsuitable for making nuclear weapons, without major reprocessing. However, the highly enriched uranium burned in many research reactors around the world is suitable for making nuclear weapons, if enough of it is available. Both power reactors and research reactors could be targets for terrorists trying to attack a reactor with a truck bomb, for the purpose of dispersing radioactive material, or trying to steal such material for the purpose of making a dirty bomb. The variations from reactor to reactor, in both attractiveness to terrorists and protection of the facility, are widespread.

The September 11 terrorist attacks demonstrated that the technical competence, available resources, level of preparation and suicidal determination of contemporary terrorist groups like al Qaeda have greatly increased over the last decade. This article will consider the likelihood that sophisticated terrorist groups could successfully launch sabotage attacks against nuclear research reactors and cause radiological releases that threaten nearby populated neighborhoods. While the theft by terrorists of highly enriched uranium (HEU) from research reactors to make relatively simple gun-type nuclear explosives has been a concern for some time, the sabotage threat to research reactors—a threat which is independent of fuel enrichment—has not been widely addressed. Nuclear regulators should reassess the level of physical protection that research reactor operators provide in light of the increased terrorist threat.

This is a presentation made at the 2002 American Nuclear Society Winter Meeting in Washington, DC on November 19, 2002.

The presentation explores:

• Motivations for Past Terrorist Threats

• Motivation for New Terrorist Threats that are More Threatening
  

• Impact

• Threats Considered Feasible
