To take a step back, Ross Reynolds talks with Dr. Raymond Zilinskas, director of the Chemical and Biological Weapons Nonproliferation Program at the Monterey Institute of International Studies about chemical weapons — what they are and why they are considered a different class than conventional weapons.
