there would have been no defense against a V-2 rocket carrying an atom bomb. Even with the short range of the rocket, all of England could have been attacked from bases in France. While only in the blueprint stage, advanced rockets capable of crossing the Atlantic could have destroyed the U.S. Eastern seaboard cities. U-boats armed with atom bombs delivered by rockets could have threatened more of North America. Fifth column sabotage using atom bombs could devastate any U.S. center. The answer to atomic warfare is to have the nations of the world unite under the United Nations framework to counter the weapons of mass destruction. Representative of the peoples of the world are asked to make laws to abolish war with the choice being clear: unite as one world confronting evil or face death. Production Technical assistance on One World or None was provided by the Federation of Atomic Scientists. The federation was founded in November 1945 by Manhattan Project scientists who helped construct the first atom bombs. 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. In early 1946, rebranded as the Federation of American Scientists, 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. In 1946, just months after atom bombs were dropped on Hiroshima and Nagasaki, the scientists who had developed nuclear technology came together to express their concerns and thoughts about the nuclear age they had unleashed through the release of a book, One World or None. The anthology of essays included contributions from Niels Bohr, Albert Einstein, and Robert Oppenheimer, among others. One World or None was critically reviewed in the New York Herald Tribune Book Review, March 17, 1946: "An illuminating, powerful, threatening and hopeful statement which will clarify a lot of confused thinking about atomic energy.” The original edition sold 100,000 copies. Quickly rising to the top of The New York Times bestsellers' list, the book spawned the short film of the same name. 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.
