This article analyzes the supply and demand sides in nuclear smuggling, as well as intermediaries between them, based on the 700 illicit trafficking incidents collected by the Stanford Database on Nuclear Smuggling, Theft, and Orphan Radiation Sources (DSTO) for the period 1991 to 2002. The supply side consists of people with access to nuclear and other radioactive material. It can be subdivided into civilian employees at source facilities, ranging from technicians to top managers; military personnel; and security guards. Intermediaries--traffickers and middlemen--can be categorized as amateurs, opportunist businessmen and firms, and organized crime groups. The demand side is represented by proliferating nation states, terrorist organizations, religious sects, separatist movements, and criminal groups or individuals interested in using nuclear and other radioactive material for malevolent purposes, such as murder, deliberate exposure, blackmail, and extortion.

There is justified concern that terrorists may use nuclear or other radioactive material to commit an act of terrorism. However, there are multiple barriers to be overcome by a terrorist to actually be able to deploy such a weapon. This article discusses four threat scenarios involving nuclear and other radioactive materials: radioactive dispersion with criminal intent, radiological malevolence, attack on a nuclear power plant, and nuclear weapons.

Altogether, 16 attack modes are identified with largely different logistical and technical requirements for their implementation. However, none of them should be considered as out of realm for a dedicated terror organization with a certain degree of sophistication.

In its relations with Peru, the United States has historically placed greatest emphasis on fighting the war on drugs. As Sendero Luminoso, The Shining Path, led an insurgency against the Peruvian government in the 1980s and 1990s, the United States provided ample support against the terrorists located in the jungle, especially those participating in the drug trade. But Peru's victory over terrorism then was due more to improved police intelligence and increased public investment, rather than success in the war on drugs. Now, in the midst of economic troubles and a difficult transition back to democracy in Peru, the Shining Path has made a resurgence. The United States again faces a choice about how to proceed - to continue focusing on the war on drugs or to provide sustained levels of investment in Peru's economy and political institutions, thereby turning this war on terror into a war on poverty.
