Nuclear terrorism is the detonation by terrorists of a yield-producing nuclear bomb containing fissile material. Although the chances of all-out nuclear war have decreased enormously compared to 1962, the chances of a nuclear terrorist attack against a single city have increased. President Obama has described nuclear terrorism as the “most immediate and extreme threat to global security.”
Imagine the consequences of a 10-kiloton weapon exploding in San Francisco, Houston, Chicago, Los Angeles, Charlotte, or any other city in the U.S. or worldwide. From the epicenter of the blast to a distance of approximately one third of a mile, every structure would be destroyed and no one would be left alive. A second circle of destruction extending three-quarters of a mile from ground zero would leave buildings looking like the Federal Office Building in Oklahoma City. A third circle reaching out one mile would be ravaged by fires and radiation.

The disastrous effects of a nuclear terrorist attack would exceed the obvious human costs. A study by the RAND Corporation estimated that direct economic costs of a nuclear terrorist attack on a U.S. port would exceed $1 trillion, about ten times the cost of 9/11. There would be immediate pressure to close all U.S. ports to prevent another attack. Given that U.S. ports carry out 7.5% of all global trade activity, the consequences for the world economy would be catastrophic. The political consequences of nuclear terrorism would be immense, and could lead to a drastic curtailment of the civil liberties that we currently take for granted.
