Tehran Conference
"Operation Long Jump" was the alleged codename given to a plot to assassinate the "Big Three" (Joseph Stalin, Winston Churchill, and Franklin Roosevelt) at the 1943 Tehran Conference. Hitler supposedly gave the command of the operation to Ernst Kaltenbrunner, chief of the RSHA, who, in turn, ceded the mission to Skorzeny. Knowledge of the whole scheme was presented to the Western Allies by Stalin's NKVD at the Tehran conference. The Soviets said they had learned about its existence from counter espionage activities against German intelligence. Their agents had found out the Nazis knew the time and place of this meeting because they had cracked a US naval code. According to the NKVD the assassination plot was foiled after they identified the German spies in Iran forcing Skorzeny to call off the mission due to inadequate intelligence.
