Andrei Sakharov Quote

A complete destruction of cities, industry, transport, and systems of education, a poisoning of fields, water, and air by radioactivity, a physical destruction of the larger part of mankind, poverty, barbarism, a return to savagery, and a genetic degeneracy of the survivors under the impact of radiation, a destruction of the material and information basis of civilization — this is a measure of the peril that threatens the world as a result of the estrangement of the world's two super-powers.
Every rational creature, finding itself on the brink of a disaster, first tries to get away from the brink and only then does it think about the satisfaction of its other needs. If mankind is to get away from the brink, it must overcome its divisions.
