Take Action Now

The scientist’s efforts helped create the movement for arms control and disarmament.

Although the popular new Netflix film, Einstein and the Bomb, purports to tell the story of the great physicist’s relationship to nuclear weapons, it ignores his vital role in rallying the world against nuclear catastrophe.

Aghast at the use of nuclear weapons in August 1945 to obliterate the cities of Hiroshima and Nagasaki, Einstein threw himself into efforts to prevent worldwide nuclear annihilation. In September, responding to a letter from Robert Hutchins, Chancellor of the University of Chicago, about nuclear weapons, Einstein contended that, “as long as nations demand unrestricted sovereignty, we shall undoubtedly be faced with still bigger wars, fought with bigger and technologically more advanced weapons.” Thus, “the most important task of intellectuals is to make this clear to the general public and to emphasize over and over again the need to establish a well-organized world government.” Four days later, he made the same point to an interviewer, insisting that “the only salvation for civilization and the human race lies in the creation of a world government, with security of nations founded upon law.”

Determined to prevent nuclear war, Einstein repeatedly hammered away at the need to replace international anarchy with a federation of nations operating under international law. In October 1945, together with other prominent Americans (among them Senator J. William Fulbright, Supreme Court Justice Owen Roberts, and novelist Thomas Mann), Einstein called for a “Federal Constitution of the World.” That November, he returned to this theme in an interview published in the Atlantic Monthly. “The release of atomic energy has not created a new problem,” he said.  “It has merely made more urgent the necessity of solving an existing one…As long as there are sovereign nations possessing great power, war is inevitable.” And war, sooner or later, would become nuclear war.

Einstein promoted these ideas through a burgeoning atomic scientists’ movement in which he played a central role. To bring the full significance of the atomic bomb to the public, the newly-formed Federation of American Scientists put together an inexpensive paperback, One World or None, with individual essays by prominent Americans. In his contribution to the book, Einstein wrote that he was “convinced there is only one way out” and this necessitated creating “a supranational organization” to “make it impossible for any country to wage war.” This hard-hitting book, which first appeared in early 1946, sold more than 100,000 copies.
