E.P. Wigner, one of the leading scientists involved in the early development of nuclear technology, had always in mind its political and social implications. In the 60s persuing his goal of a peaceful open world he began to develop the concept of Civil Defense against nuclear attacks. Looking back one might see this as an alternative to the concept of the Nuclear Shield. The present volume contains a selection of Wigner''s writings on this subject. It is annotated by Conrad Chester.
