Defense of the American Jewish Soviet spies Julius and Ethel Rosenberg surged in November and December 1952 and was organized by the Communist Party of the Soviet Union—confirmation of which occurred with the publication of KGB documents obtained by Alexander Vassiliev in 2011. Proponents of clemency argued that the Rosenbergs were actually "innocent Jewish peace activists". According to American historian Ronald Radosh, the Soviet Union's goal was "to deflect the world's attention from the sordid execution of the innocent trial defendants in Prague".
