CIA's secret mind-control horrors exposed as new MKUltra claims emerge

A secret CIA program that experimented on unwitting Americans has once again been thrust into the spotlight, with lawmakers hearing chilling allegations of drugging, psychological torture and deadly human experimentation.

Several congressional officials convened on Capitol Hill on Tuesday to hear testimony about Project MKUltra, the notorious Cold War program that sought to develop techniques for interrogation, brainwashing and mind control.

Lawmakers heard claims that the CIA lured Americans into brothels and secretly dosed them with hallucinogens, fed prisoners massive quantities of LSD for weeks and conducted experiments aimed at erasing memories and controlling human behavior.

Witnesses further alleged that some victims died during the experiments and that the true number of casualties may never be known.

Historian Stephen Kinzer told lawmakers under oath: 'MKULTRA conducted the most extreme experiments on human beings that have ever been carried out by a US government agency. 'By any standard, they qualify as medical torture.'

Project MKUltra was launched by the CIA in 1953 amid fears that the Soviet Union and China had developed advanced brainwashing techniques.

Kinzer and investigative journalist Tom O’Neill, the second witness, also warned that the sinister CIA experiments could still be happening in secret decades later.

Kinzer said: 'There have been enormous advances in cyber technology, neuroscience, and artificial intelligence. Covert agencies may have access to tools for mind control that Sidney Gottlieb [the then-CIA boss] could not have imagined.'

Gottlieb believed that to implant a new mind into someone, researchers first had to destroy the one that already existed.

Subjects included criminals, mental patients, drug addicts, Army soldiers and ordinary citizens who were given drugs without their knowledge.

The testimonies also raised fresh questions about whether the program achieved far more than the government has admitted and whether a modern version of MKUltra could still exist today.

'The American people deserve the complete record,' Kinzer told lawmakers.

'The victims and their families deserve acknowledgment, accountability, and justice.'

The hearing laid bare the staggering scope of the operation.

According to congressional testimony, MKUltra consisted of at least 149 subprojects, operated across more than 80 institutions and involved 185 non-government researchers.

The CIA secretly funded hospitals and research facilities so unwitting patients could be used as experimental subjects.

Witnesses said Americans were subjected to LSD, electroshock, hypnosis, sensory deprivation and psychological torture without their knowledge or consent.

One of the most notorious examples was Operation Midnight Climax.

The CIA set up safe houses and brothels where unsuspecting men were lured in by prostitutes, secretly dosed with hallucinogens and observed through one-way mirrors.

Kinzer testified that there was 'not even the pretense of scientific experimentation.'

He said the operation appeared to have become an opportunity for agency officials to indulge themselves while conducting unauthorized experiments on Americans.

Even more disturbing were allegations surrounding psychiatrist Dr Louis Jolyon West, whom investigative journalist Tom O'Neill said worked closely with Gottlieb.

After combing through hundreds of boxes of West's papers, O'Neill discovered correspondence that he described as a blueprint for MKUltra's true objectives.

According to the documents, West proposed using LSD and hypnosis to induce 'trance states,' 'confusions,' 'amnesias' and other 'specific mental disorders' in unwilling subjects who would remember nothing afterward.

'These experiments, needless to say, must eventually be put to test in practical trials in the field,' O'Neill testified.

The ultimate goal, O'Neill claimed, was to learn how to extract information, implant false information and alter an individual's beliefs and loyalties.

'In other words, to completely switch their allegiance from one group or leader to another,' he said.

One of the most explosive claims involved a 1956 report in which West allegedly wrote that he had learned how to replace 'true memories' with false ones.

O'Neil said under oath: 'It has been found to be feasible to take the memory of a definite event in the life of an individual and, through hypnotic suggestion, bring about the subsequent conscious recall to the effect that this event never actually took place, but that a different (fictional) event actually did occur.'

He called it the 'Holy Grail' of MKUltra, saying: 'The secret to taking possession of a person's mind and controlling their behavior.'

The hearing also revisited some of the program's darkest alleged abuses.

Kinzer described a case involving a group of African American inmates in a federal prison in Kentucky who were reportedly fed double, triple and quadruple doses of LSD every day for 77 days.

A memorandum dated December 2, 1953 provided details about Olson's death and included illegible Xeroxed copy of the death certificate

'We have no idea what happened to them,' he told lawmakers.

Another major focus was the death of Dr Frank Olson, a scientist who worked on CIA biological weapons programs and secretly participated in MKUltra.

Olson died in 1953 after plunging from a New York City hotel window, a death officially ruled a suicide.

But Kinzer told Congress that he believes Olson was murdered because he intended to expose the government's biological weapons activities and reveal what he knew about lethal MKUltra experiments.

'The Frank Olson case, that was a murder,' testified O’Neill. 'I don't believe that was a suicide.'

'The motivation was [that] he was going to be a whistleblower and announce that the US government was using biological weapons in the Korean War and was also going to share what he knew about MKUltra experiments, including lethal experiments.'

Witnesses also claimed that people were 'experimented to death' at a CIA safe house in Germany and suggested that the true number of victims may never be known.

The secrecy surrounding MKUltra was compounded when then-CIA Director Richard Helms ordered the destruction of the program's records in 1973.

Thousands of documents were shredded or burned, leaving only a fraction of the operation's history intact. Yet Kinzer warned that the story may not be over.

Although Gottlieb eventually concluded that mind control had failed, Kinzer said advances in artificial intelligence, cyber technology and neuroscience have dramatically changed the landscape.
