Key point: An assassination attempt on world leaders meeting in Iran would have changed history.
In German it was called Operation Rösselsprung, which translates to “Long Jump.” Its goal was to kill or kidnap the Allies’ “Big Three” leaders––Soviet Premier Josef Stalin, British Prime Minister Winston S. Churchill, and American President Franklin D. Roosevelt—when they met in Tehran, Iran, in November 1943. That the plan did not succeed is attributable to smart intelligence work, a drunken disclosure, and a bit of good luck.
Perhaps no operation was more audacious or had greater consequences to the war’s outcome if it had succeeded than Long Jump. Former Soviet Lieutenant General and KGB intelligence officer Vadim Kirpichenko said, “The first secret report that this act was being planned came from Soviet intelligence officer Nikolai Kuznetsov, who learnt about it during a conversation with SS-Sturmbannführer Ulrich von Ortel. Ortel was the chief of the sabotage group in Copenhagen, which was preparing the operation. While drunk, the senior German counterintelligence officer blurted out that preparations were underway to assassinate the Big Three. Later the Soviet Union and Britain discovered other facts confirming that preparations had been made to assassinate Stalin, Churchill, and Roosevelt.”
