The mysterious CIA Project MKUltra may have been involved in trying to create brainwashed assassins for the US Government who may in turn have been involved in a series of high profile assassinations between 1963 and 1980. That’s the conspiracy theory. However, many people don’t realise that MKUltra’s origins were at Dachau Concentration Camp and SS interrogation experiments using hypnosis and psychedelic drugs, and that many of the Nazi doctors were later recruited by the CIA and worked on MKUltra.
