The Rosenberg Ring Revealed: Industrial-Scale Conventional and Nuclear Espionage

New evidence from the KGB’s archives reveals that Julius Rosenberg’s espionage ring was larger and caused more damage to U.S. security than has been previously understood. Rosenberg’s prosecution centered on his recruitment of David Greenglass to spy on the Manhattan Project. Notes smuggled out of Moscow by Alexander Vassiliev show that Rosenberg also recruited Russell McNutt as a nuclear spy. The Rosenberg ring’s primary contribution to the USSR, however, was a wealth of detailed information about non-nuclear weapons systems that were critical elements of the early Cold War Soviet arsenal.
