When Nazi Germany began a secret weapons program called The Uranium Club in April 1939, Stalin was alerted by his American and British spies of the possibility that German scientists were working to develop an atomic bomb. The British Government and the United States, and Stalin, realized that if Hitler used The Atom Bomb, it could mean the end of the West or the end of the world. John Harte's new book about The Manhattan Project describes how Soviet Russia's leading spymasters in Moscow Centre obtained information from British and American physicists to make a Soviet atomic bomb at each and every stage when the American bomb was developed at Los Alamos in New Mexico.
