We are all familiar with the passionate and closely argued appeal against censorship by the outstanding Soviet writer A. Solzhenitsyn.He as well as G… - Andrei Sakharov

The author is quite aware of the monstrous relations in human and international affairs brought forth by the egotistical principle of capital when it is not under pressure from socialist and progressive forces. He also thinks, however, that progressives in the West understand this better than he does and are waging a struggle against these manifestations. The author is concentrating his attention on what is before his eyes and on what is obstructing, from his point of view, a worldwide overcoming of estrangement, obstructing the struggle for democracy, social progress, and intellectual freedom.

The experience of past wars shows that the first use of a new technical or tactical method of attack is usually highly effective even if a simple antidote can soon be developed. But in a thermonuclear war the first blow may be the decisive one and render null and void years of work and billions spent on creation of an anti-missile system.

Three technical aspects of thermonuclear weapons have made thermonuclear war a peril to the very existence of humanity. These aspects are: the enormous destructive power of a thermonuclear explosion, the relative cheapness of rocket-thermonuclear weapons, and the practical impos­sibility of an effective defense against a massive rocket-nuclear attack.
