This would be a more difficult feat than chemical or biological terrorism, but the massive, assured, instantaneous, and comprehensive destruction of life and property that would result may make this a priority for terrorists. While efforts to reduce the chances of this happening have been underway since long before last September 11 – and have recently been bolstered in some respects – the size and the speed of the U.S. and international response is not yet remotely commensurate with the magnitude of the threat. This report briefly reviews the dimensions of the danger and the efforts now underway to combat it, and then recommends seven sets of actions that ought to be undertaken immediately to bolster the barriers against this horrifying threat. Dimensions of the Danger The attacks of September 11 demonstrated that the threat from well-organized terrorist groups with global reach, bent on inflicting massive harm to the people of the United States, is not hypothetical but real. Terrorists have already tried chemical and biological weapons – nerve gas in the Tokyo subway, anthrax mailed to U.S. public figures. Their failure to use nuclear weapons so far must be assumed to be due to lack of means rather than lack of motivation. But they are trying. One route to terrorists’ acquiring a nuclear weapon would be for them to steal one intact from the stockpile of a country possessing such weapons, or to be sold or given one by such a country, or to buy or steal one from another subnational group that had obtained it in one of these ways. Another route to a terrorist bomb is via stealing the needed nuclear- explosive material (either plutonium or highly enriched uranium) – or buying it from someone else who has stolen it – and using this to fabricate a bomb from scratch. With enough nuclear material in hand (ranging from a few kilograms of plutonium for an implosion weapon to a few tens of kilograms of highly enriched uranium for the technically simpler gun-type design), it would likely be within the reach of a sophisticated and well- organized terrorist group to build at least a crude nuclear explosive. If stolen or built abroad, a nuclear bomb might be delivered to the United States, intact or in pieces, by ship or aircraft or truck, or the materials could be smuggled in and the bomb constructed at the site of its intended use. Intercepting a smuggled nuclear weapon or the materials for one at the U.S. border would not be easy. The length of the border, the diversity of means of transport, and the ease of shielding the radiation from plutonium or highly enriched uranium all operate in favor of the terrorists. The huge volume of drugs successfully smuggled into this country provides an alarming reference point. The detonation of such a bomb in a U.S. (or any other) city would be a catastrophe almost beyond imagination. A 10-kiloton nuclear explosion (from a “small” tactical nuclear weapon from an existing arsenal or a well-executed terrorist design) would create a circle of vi EXECUTIVE SUMMARY near-total destruction perhaps 2 miles in diameter. Even a 1-kiloton “fizzle” from a badly executed terrorist
