The Dark History of the CIA

HERE'S SOMETHING TO SIT WITH: the United States government ran a program to test mind control drugs on unwitting American citizens. Psychiatric patients, prisoners, hospital patients, even military personnel were dosed with LSD and other experimental compounds without their knowledge or consent. When the program was shut down, the CIA director ordered all files destroyed. Most were. What survived was found in a financial records room during a 1977 Congressional investigation.

That was MKUltra. It is not a conspiracy theory. It is documented history, confirmed by Senate hearings, partially recovered files, and survivor testimony. And it is far from the only documented program in the CIA's history that strains credulity precisely because it happened.

The Origins: Intelligence Born From War

The CIA was created in 1947, two years after the end of World War II, by the National Security Act signed by Harry Truman. Its predecessor, the Office of Strategic Services (OSS), had been a wartime intelligence and sabotage organization. Many OSS veterans moved into the new CIA, bringing with them the wartime mentality that anything was justified if it served the strategic objective.

The early Cold War context is essential for understanding what followed. American leaders genuinely believed that Soviet communism represented an existential threat to Western civilization, and that the Soviets were willing to use any means necessary. This belief, whether fully accurate or not, created internal authorization for the CIA to operate outside conventional legal and moral constraints. If the enemy had no rules, the thinking went, then operating with rules was a form of unilateral disarmament.

What this rationalization produced, documented in declassified files over the following decades, is a record that includes torture programs, political assassinations, coups against elected governments, domestic surveillance of American citizens, and human experimentation on a scale that would be prosecuted as serious crime in any other context.

Overthrowing Governments: Iran and Guatemala

In 1953, the CIA orchestrated the overthrow of Mohammad Mosaddegh, the democratically elected Prime Minister of Iran. Operation AJAX, run jointly with British intelligence, used propaganda, bribed politicians and military officers, and organized street mobs to destabilize the Mosaddegh government after it nationalized the Anglo-Iranian Oil Company (now BP). The operation restored Shah Mohammad Reza Pahlavi to power.

The CIA's own internal history, written in 1954 and declassified in 2013, describes the operation in detail and is frank about what it was: the removal of a foreign government through covert action to protect Western oil interests. The Iranian Revolution of 1979, which produced the Islamic Republic that America has been in conflict with ever since, cannot be understood without 1953.

In 1954, the CIA repeated the performance in Guatemala. Operation PBSUCCESS removed President Jacobo Arbenz, who had moved to redistribute some of the United Fruit Company's vast Guatemalan landholdings. The operation used a combination of psychological warfare, air interdiction by CIA-piloted planes, and support for an exile invasion force. Arbenz resigned. What followed was decades of military dictatorship and civil war that killed hundreds of thousands of Guatemalans.

These two operations established a template that the CIA applied across Latin America, the Middle East, and parts of Africa and Southeast Asia throughout the Cold War.

MKUltra: The Mind Control Program

Between 1953 and 1973, the CIA ran a program called MKUltra, officially directed at finding ways to control human behavior, extract information under interrogation, and potentially create "Manchurian Candidate"-style operatives who could be directed to act without conscious awareness. The program funded research at universities, hospitals, and prisons, often without the knowledge of the institutions involved and almost always without the knowledge of the subjects.

Experiments included prolonged sensory deprivation, electroconvulsive therapy administered without consent, hypnosis, and above all psychoactive drugs. LSD was the primary compound of interest, but researchers also used mescaline, heroin, barbiturates, and other substances. Subjects included psychiatric patients, prison inmates, people in Veterans Administration hospitals, and in at least one documented subproject, sex workers lured to a CIA safe house in San Francisco where operatives observed their reactions through one-way mirrors.

Frank Olson, a CIA scientist, died in 1953 under circumstances that remain disputed. He fell from a hotel window in New York nine days after being dosed with LSD without his knowledge at a CIA gathering. His death was ruled a suicide. His family has consistently disputed this conclusion, and when his body was exhumed in 1994, the forensic evidence suggested he had been struck on the head before going through the window.

Director Richard Helms ordered the MKUltra files destroyed in 1973 when Watergate was exposing intelligence community activities and he feared Congressional scrutiny. Approximately 20,000 documents survived because they had been misfiled in a financial records building not covered by the destruction order. These surviving files are what the 1977 Senate investigation, the Church Committee hearings, actually examined.

Operation Condor and South American Death Squads

In the 1970s, the CIA coordinated a multinational intelligence and assassination network across South America known as Operation Condor. Participating governments included Argentina, Bolivia, Brazil, Chile, Paraguay, and Uruguay, all military dictatorships. The program facilitated the tracking, detention, torture, and murder of political dissidents across national borders.

Estimates of people killed under Condor range from 60,000 to 80,000, with hundreds of thousands more tortured and detained. CIA documents show the agency provided training, communications infrastructure, and intelligence sharing. The degree of direct operational involvement versus passive facilitation remains contested, but the agency's awareness and at minimum logistical support is documented.

Domestic Surveillance: COINTELPRO and Operation CHAOS

The CIA's legal mandate prohibits it from operating domestically against American citizens. The FBI's COINTELPRO program (1956-1971) was technically domestic, but the CIA ran its own domestic surveillance operation, Operation CHAOS, from 1967 to 1974. CHAOS targeted anti-Vietnam War protesters, civil rights organizations, and other domestic dissidents on the theory that they might be receiving foreign direction or funding.

CHAOS compiled files on more than 7,000 American citizens. It infiltrated domestic political groups. It shared information with local police red squads. The program was a direct violation of the CIA's charter, a fact the agency itself acknowledged internally while continuing the program anyway.

The Phoenix Program

In Vietnam, the CIA ran the Phoenix Program from 1965 to 1972, a counterinsurgency effort designed to identify and neutralize the Viet Cong political infrastructure. "Neutralize" meant capture, defection, or killing. The program killed an estimated 20,000 to 40,000 people by CIA and South Vietnamese accounts, though Vietnamese sources put the number much higher.

The program's methods included systematic torture at interrogation facilities. Former CIA director William Colby, who ran Phoenix, acknowledged in Congressional testimony that significant abuses occurred. Provincial Reconnaissance Units, paramilitary teams operating under Phoenix, were responsible for killings that in many cases targeted people identified as VC infrastructure but with little to no due process or verification.

Post-Cold War: From Extraordinary Rendition to Enhanced Interrogation

After September 11, 2001, the CIA was authorized to operate detention and interrogation facilities outside the United States, the "black sites" documented in the 2014 Senate Intelligence Committee report on the CIA's detention and interrogation program. The report, based on 6.3 million pages of CIA documents, concluded that the "enhanced interrogation" techniques used, which included waterboarding, sleep deprivation to the point of hallucination, stress positions, and rectal feeding, constituted torture, that they were not effective in producing reliable intelligence, and that the CIA systematically misled Congress and the executive branch about the program's scope and results.

No CIA officer was prosecuted. The Senate report's full 6,700-page version remains classified.

What the Record Actually Shows

The CIA has also done things that are defensible and, by most accounts, necessary: tracking Soviet weapons programs, monitoring nuclear proliferation, penetrating terrorist networks, providing warning of military buildups. The case for a capable intelligence service is not difficult to make.

But the documented history of the CIA's worst programs reveals something important about what happens when any institution is given broad authority, minimal oversight, and a mandate to operate in secrecy. The abuses were not carried out by uniquely evil people. They were carried out by people who had convinced themselves that the stakes were high enough to justify the methods.

That conviction, more than any individual director or operation, is the through-line in the CIA's dark history. It is also the warning the record carries for anyone paying attention.
