CIA docs confirm MK-ULTRA tests on Korean POWs

Over 1,200 newly released CIA records confirm that North Korean prisoners of war were subjected to Project Bluebird experiments in 1950. The documents detail plans for 'personality control' using sedatives, stimulants, polygraph testing, hypnosis, and experimental jet-injection devices on 25 POWs held in Japan. The files reveal no evidence that enemy forces conducted similar experiments on American soldiers, undermining the CIA's narrative that such programs were defensive responses. A 1952 memo acknowledged the lack of evidence but indicated the agency proceeded without confirmed threat justification.
