I can't remember the guy's name but his stuff is on YouTube.
“that the US government not only took in high-ranking NAZI scientists after WWII but gave them a free hand to continue their amazingly advanced though shockingly amoral and cruel research.”
There are a lot of extrapolations and nuttiness out there about this stuff, but it is based on some disclosed government documents.
“Project MKULTRA, MK-ULTRA or MKPLUSULTRA, was the code name for a covert, illegal CIA human research program, run by the Office of Scientific Intelligence. This official U.S. government program began in the early 1950s, continuing at least through the late 1960s, and it used U.S. and Canadian citizens as its test subjects.”
“A precursor of the MKULTRA program began in 1945 when the Joint Intelligence Objectives Agency was established and given direct responsibility for Operation Paperclip. Operation Paperclip was a program to recruit former Nazi scientists. Some of these scientists studied torture and brainwashing, and several had just been identified and prosecuted as war criminals during the Nuremberg Trials.[10][11]
Several secret U.S. government projects grew out of Operation Paperclip. These projects included Project CHATTER (established 1947), and Project BLUEBIRD (established 1950), which was renamed Project ARTICHOKE in 1951. Their purpose was to study mind-control, interrogation, behavior modification and related topics.”

Now, good luck trying to weed out the truth from the disinformation and the crackpot theories when it comes to this stuff!
