The Soviets efforts to build a hydrogen bomb began
with the design by Andrei Sakharov and Vitaly Ginzburg in 1949.
Sahkarov later became a dissident and activist for disarmament, peace, and human rights.
Enrico Fermi wrote the following about the hydrogen bomb on 6 May 1954:
Such a weapon goes far beyond any military objective
and enters the range of very great natural catastrophes.
By its very nature it cannot be confined to a military objective
but becomes a weapon which in practical effect is almost one of genocide.
It is clear that the use of such a weapon cannot be justified
on any ethical ground which gives a human being a certain individuality and dignity
even if he happens to be a resident of an enemy country. . . .
The fact that no limits exist to the destructiveness of this weapon
makes its very existence and the knowledge of its construction
a danger to humanity as a whole. It is necessarily an evil thing considered in any light.
Albert Einstein wrote on 22 January 1947:
Through the release of atomic energy, our generation has brought into the world the most revolutionary force
since prehistoric man’s discovery of fire.
This basic force of the universe cannot be fitted into the outmoded concept of narrow nationalisms.
For there is no secret and there is no defense;
there is no possibility of control except through the aroused understanding and insistence of the peoples of the world.
We scientists recognise our inescapable responsibility to carry to our fellow citizens an understanding
of atomic energy and its implication for society. In this lies our only security and our only hope –
we believe that an informed citizenry will act for life and not for death.
