Asymmetric and Terrorist Attacks With Chemical Weapons

The US must plan its Homeland defense policies and programs for a future in which there is no way to predict the weapon that will be used or the method chosen to deliver a weapon which can range from a small suicide attack by an American citizen to the covert delivery of a nuclear weapon by a foreign state. There is no reason the US should assume that some convenient Gaussian curve or standard deviation, will make small or medium level attacks a higher priority over time than more lethal forms.
