Nuclear treason is nothing new. It happened in the 1940s when U.S. Communist Party members smuggled Manhattan Project secrets to Stalin’s Soviet Union, allowing him to explode his first bomb in 1949, just four years after Hiroshima and Nagasaki. It happened again when Pakistani nuclear scientist A.Q. Khan, working at a Dutch nuclear facility, passed on the bomb secrets to Pakistan. Pakistan’s nuclear stockpile is now reported to be vulnerable to a jihadist attack.
