Fourth Spy Unearthed in U.S. Atomic Bomb Project

His Soviet code name was Godsend, and he came to Los Alamos from a family of secret agents.

Nuclear Proliferation
Nuclear power was the failed answer to the horrors of the atomic bomb - the so-called "Peaceful Atom." However, the two technologies are inextricably linked. Countries such as India, Pakistan, Israel and North Korea clandestinely developed nuclear weapons using the infrastructure, technology and know-how of their "civilian" nuclear programs. Contained expansion of nuclear power across the globe only increases the chances of nuclear weapons development and is counterproductive to disarmament.
