This book provides an analysis of the development and deployment of
chemical weapons from 700BC to the present day. The First World War is
examined in detail since it remains the most significant experience of
the chemical threat, but the Second World War, and post-war conflicts
are also evaluated. Additionally, protocols attempting to control the
proliferation and use of chemical weapons are assessed. Finally, the
book examines the threat (real and imagined) from a chemical warfare
attack today by rationally assessing to what extent terrorist groups
around the world are capable of making and using such weapons.
