The following statement comes from the U.S. Domestic Nuclear Defense Office (DNDO). "Covert nuclear attack is the foremost threat facing the United States (U.S.) and is a primary focus of the war on terror.  The safety of the U.S. depends upon its ability to design and field systems to detect and interdict smuggled nuclear weapons and materials.  The Department of Homeland Security (DHS) is chartered to develop, acquire, and support deployment and improvement of a domestic system to detect attempts to import, assemble, or transport a nuclear explosive device, fissile material or radiological material intended for illicit use."

There are many reasons that a nuclear attack is possible. Most are related to the relative increase in loss of control of the fissile materials. Many experts including Dr. Graham Allison in his book "Nuclear Terrorism" and Capt. Steven Flynn in "America the Vulnerable" have stated it is an issue of when not if.

Moreover, in addition to nuclear weapons, there are lower concept, easier to make radiological dispersal devices (or dirty bombs) that while less horrific than a nuclear weapon could still cause widespread terror, radioactive contamination and would have significant financial impact on the country. The following bullets summarize the reasons for vigilance and why the United States and other friendly foreign governments are paying attention to this risk and attempting to emplace a variety of instruments, policies and methods to make the possibility of a radiation or nuclear weapon less probable.
