This collection of studies is one of the most lucid and sober analyses of the dangers of nuclear war, which mankind is facing. Written by natural and social scientists, the book should be read both by statesmen and by the general public. Looking towards the end of the century it makes clear the growing dangers. Avoiding complacency on the other hand, and prophecies of doom on the other, it contains a message of hope and an appeal to wisdom.

Foreword by: Pierre Elliott Trudeau
