Declassified files expose secret security plans for the 1943 Tehran Conference

Declassified documents have revealed new details about the security arrangements for the 1943 Tehran Conference. The historic meeting brought together Soviet Premier Stalin, U.S. President Roosevelt, and British Prime Minister Churchill. Recently released files from Russia’s FSB show how intelligence teams worked behind the scenes to protect the event.

Planning for the conference began months before the final decision. Stalin first suggested Tehran as a meeting place in August 1943. The location was officially confirmed on November 8, just weeks before the summit took place.

The newly released documents provide a clearer picture of the security preparations for the Tehran Conference. The FSB’s records confirm that Soviet social security played a key role in safeguarding the event. The conference itself remained unmarked by any major security incidents during its four-day run.
