Perhaps no scientific development has shaped the course of modern history as much as the harnessing of nuclear energy. Yet, the twentieth century might have turned out differently had greater influence over this technology been exercised by Great Britain, whose scientists were at the forefront of research into nuclear weapons at the beginning of World War II.
As award-winning biographer and science writer Graham Farmelo describes in Churchill's Bomb, the British set out to investigate the possibility of building nuclear weapons before their American colleagues. But when scientists in Britain first discovered a way to build an atomic bomb, Prime Minister Winston Churchill did not make the most of his country's lead and was slow to realize the bomb's strategic implications. This was odd - he prided himself on recognizing the military potential of new science and, in the 1920's and 1930's, had repeatedly pointed out that nuclear weapons would likely be developed soon. In developing the bomb, however, he marginalized some of his country's most brilliant scientists, and also failed to capitalize on Franklin Roosevelt's generous offer to work jointly on the bomb - and ultimately ceded Britain's initiative to the Americans, whose successful development and deployment of the bomb placed the United States in a position of supreme power at the dawn of the nuclear age. Churchill came to be terrified by the possibility of thermonuclear war and emerged as a pioneer of détente in the early stages of the Cold War.
Contrasting Churchill's often inattentive leadership with Franklin Roosevelt's decisiveness, Churchill's Bomb reveals the secret history of the weapon that transformed modern geopolitics.
