A Higher Form of Killing was first published to great acclaim in 1982. The authors have written a new Introduction and a new Epilogue to take account of the events that have happened since the early 1980s - including the break-up of the former Soviet Union and the black market that appeared in chemical and biological weapons, the acquisition of these weapons by various Third World states, the attempts of various countries like Iraq to build up arsenals of these weapons and, most recently, the use of these weapons in terrorist attacks.As the authors point out, the two generations since the Second World War lived with the threat of nuclear annihilation. Now a new generation must learn to live with weapons that are more insidious and potentially more devastating.
