Robert Oppenheimer

We have made a thing, a most terrible weapon, that has altered the nature of the world and of man.

We have to ask, what is this thing for? What is it for, other than to kill people?

It is not a weapon for innocent people. It is not a weapon for cities.

The experience of the war has made it clear that the future of civilization depends on the development of a world community.

I believe that in the long run, the only way we can survive is to make the world safe for peace.

The atom bomb is a weapon of terror, a weapon of retaliation, and a weapon of mass destruction.

We have used a weapon that has changed the course of history.

In an important sense, the atomic bomb was made in Germany.

The atomic bomb is not merely a new weapon, but a new thing in the world.

We have opened a new age, and it is an age of terror.

The atomic bomb is a demonstration of the power of science, but it is also a demonstration of the folly of man.

We have made a rod for our own backs.

The atomic bomb is a symbol of man's destructive power, but it is also a symbol of man's ability to create.

We have to live with the fact that we have unleashed a terrible force.

The atomic bomb is a warning to mankind that we must find a way to live together in peace.

We have to find a way to control this weapon, or it will control us.

The physicists have known sin; and this is a knowledge which they cannot lose. It is a knowledge which has changed them forever.

The atomic bomb is a terrible thing, but it is also a beautiful thing.

We have to live with the consequences of our actions.

The atomic bomb has taught us that we are not masters of our own destiny.
