Chemical weapons have not been used effectively in attacks on the American homeland. Reports that the bombers of the World Trade Center considered trying to add a chemical weapon like sodium cyanide to their explosives seem to be untrue, and led to an unsubstantiated assertion by the trial judge. There have, however, been a number of attempts to use chemical weapons by domestic extremists and individuals. For example, in 1997, members of the KKK plotted to place an improvised explosive device on a hydrogen sulfide tank at a refinery near Dallas, Texas. There is a well-established, low-level risk that such weapons will be used in the future, although there is no way to predict the frequency of such attacks, their scale, potential success, or lethality.

There is a wide spectrum of potential threats to the American homeland that do not involve the threat of overt attacks by states using long-range missiles or conventional military forces. Such threats include covert attacks by state actors, state use of proxies, independent terrorist and extremist attacks by foreign groups or individuals, and independent terrorist and extremist attacks by residents of the US. These threats are currently limited in scope and frequency. No pattern of actual attacks on US territory has yet emerged that provides a clear basis for predicting how serious any given form of attack will be in the future, what means of attack will be used, or how lethal new forms of attack will be if they are successful.
