Albert Einstein The Menace Of Mass Destruction Full Speech Apr 2026

The atom has changed everything, save our mode of thinking. And thus we drift toward unparalleled catastrophe.

It is a question for the human soul.

I answer: We must think as citizens of the world, not as citizens of any single nation.

And we have two bombs now? No. We have many. And soon, other nations will have them too. There is no secret to be kept forever. albert einstein the menace of mass destruction full speech

I am grateful for this opportunity to speak with you tonight. I speak not as a physicist, but as a human being — a citizen of this world, deeply troubled by the shadow that has fallen upon it.

By Albert Einstein (May 31, 1946)

Now, I am often asked: "Professor Einstein, what can we do?" The atom has changed everything, save our mode of thinking

Ladies and Gentlemen,

The atomic bomb has made the old patterns of war obsolete. In the past, nations could fight and lose and survive. The losing army could retreat, surrender, rebuild. But with these new weapons, there will be no rebuilding. There will be no retreat. There will be no surrender, because there will be no one left to surrender.

Thank you. End of speech.

When I first sent my letter to President Roosevelt in 1939, I did so out of the deepest fear that Nazi Germany would succeed in building an atomic bomb. We had reason to believe their scientists were capable of such a horror. I acted to prevent a nightmare.

Today, the nightmare is no longer a threat. It is a reality. The bomb was made, and it was used.
