One World or None (1946) is an instructional documentary short film produced by the National Committee on Atomic Information in conjunction with Philip Ragan Productions.

[1][Note 1]One World or None established that throughout history, scientists from many nations have made great advances and discoveries and have shared that knowledge globally.

The periodic table was developed by Russian chemist Dmitri Mendeleev, British scientist J. J. Thomson and his team discovered the principle of the electron, and German theorist Albert Einstein came up with the theory of relativity.

Further nuclear research was carried out by Enrico Fermi, who transmuted uranium based on Japanese physicist Hantaro Nagaoka's theories on the atom.

According to information provided by the Federation of American Scientists, the massive destructive power of the atom bomb is contrasted with earlier weapons of war.

Attacks by the Axis powers could have brought World War II to an end, as there would have been no defense against a V-2 rocket carrying an atom bomb.

Their credo was that all scientists, engineers, and other "technically-trained thinkers" have an ethical obligation to ensure the technological "fruits of their intellect and labor" are applied to the benefit of humanity.

[3] In early 1946, rebranded as the Federation of American Scientists (FAS), the organization took efforts to broaden and diversify its network of supporters to include all who want to reduce nuclear dangers and ultimately prevent global catastrophe.

He saw the film as a step toward raising awareness of the need for international control over nuclear energy and believed that it required additional support and an extended educational campaign.

Philip Ragan Productions was responsible for One World or None, using a mix of animation and live-action stock footage, including scenes from Hiroshima and the Nuremberg War Trials.
