The Cold War
The Cold War pitted the United States and Soviet Union in a decades-long contest fought through proxies, espionage, and secret programs rather than direct war. Its declassified operations, from psychological warfare to undersea wiretaps to human experiments, are among the best-documented conspiracies on record. These files gather the era's covert programs and the disputed events around them.

The CIA secretly influenced the news media during the Cold War
That the CIA covertly recruited journalists and shaped US news coverage during the Cold War sounds like a classic conspiracy theory. It isn't one: a Senate investigation and a major press exposé both confirmed the core relationships were real. What is not confirmed is the popular name attached to them, or the idea of a single, centrally run operation that controlled the American press.
Read the case file →The CIA ran a secret program to overthrow Castro and plotted his assassination
Operation Mongoose, also called the Cuban Project, was a real, government-wide covert program authorized by President Kennedy in November 1961 to sabotage and overthrow Fidel Castro's government after the Bay of Pigs disaster. Alongside it, and separately, the CIA ran assassination plots against Castro (some using organized-crime contacts) later confirmed in detail by the Senate's Church Committee. The program is not a theory; it is documented history. What remains genuinely contested is how far up the chain of command the assassination plotting was known and approved.

Not a theory in the usual sense but a covert operation the US government spent sixty years denying, then admitted in its own words. In August 1953, the CIA and British intelligence engineered the overthrow of Iran's democratically elected prime minister, Mohammad Mossadegh, after he nationalized the British-controlled oil industry, and installed the Shah as an absolute monarch in his place.

Beginning in the mid-1970s, the military dictatorships of Chile, Argentina, Uruguay, Paraguay, Bolivia and Brazil ran a secret joint operation, code-named Condor, to hunt down, kidnap, torture and kill each other's political exiles across borders, reaching as far as a car bomb on a Washington, D.C. street. It sounded like the kind of thing only a paranoid exile would claim, until a judge in Paraguay pulled three tons of the regimes' own paperwork out of a police station.
Read the case file →NATO and the CIA ran secret armies across Western Europe during the Cold War
Not a rumor but an admitted state secret: for roughly forty years, NATO and Western European intelligence services ran clandestine 'stay-behind' paramilitary networks, armed and trained to resist a Soviet occupation that never came. Italy's prime minister confirmed it to Parliament in 1990, and the European Parliament condemned it days later. What remains genuinely disputed is a darker, narrower claim layered on top: that these networks were turned against their own citizens.
Read the case file →The US military drew up plans to fake terror attacks and blame Cuba
Long before 'false flag' entered everyday vocabulary, America's own Joint Chiefs of Staff put their names to a plan to stage fake terrorism against American citizens and pin it on Cuba. The proposal is real, signed, and declassified. It was also rejected, and it never happened.
Read the case file →The US secretly brought Nazi scientists to America after WWII
Not a rumor but a documented program: after WWII, US intelligence recruited around 1,600 German scientists, engineers and technicians (including rocket engineer Wernher von Braun) and in a number of cases rewrote their Nazi Party and SS histories to slip them past America's own immigration bar on 'ardent Nazis'.

For a week in September 1950 the U.S. Navy sprayed a cloud of live bacteria over San Francisco to see how a real biological attack might spread. The program stayed secret for a quarter-century, surfaced in the press in 1976, and was confirmed under oath in 1977, by which time one of the supposedly harmless test bacteria, Serratia marcescens, had been reclassified as a genuine human pathogen and blamed for a fatal infection.

In the early-to-mid 1970s the Church of Scientology ran a coordinated campaign, code-named Operation Snow White, to plant covert operatives inside federal agencies and steal or destroy government files it judged unfavorable to Scientology and its founder, a scheme so extensive that when the FBI finally raided its offices in 1977, the paper trail alone was enough to convict eleven of the Church's most senior officials.
Read the case file →The US Navy, NSA, and CIA secretly wiretapped a Soviet undersea military cable in the Sea of Okhotsk
Not a rumor but a documented Cold War intelligence operation: in the early 1970s, US Navy divers working from a modified submarine placed a covert tap on a Soviet military communications cable on the floor of the Sea of Okhotsk, recording years of unencrypted Soviet naval traffic, until an NSA analyst sold the secret to the KGB and was convicted of espionage for it.
Read the case file →The CIA secretly experimented on people with drugs and mind control
Long dismissed as paranoia, the claim that the CIA ran covert mind-control and drug experiments on often unwitting subjects turned out to be documented fact: a case study in why institutional distrust is not always irrational.
Read the case file →The FBI ran a secret campaign to spy on and sabotage domestic political activists
For fifteen years the FBI ran a secret program, code-named COINTELPRO, to not just watch but actively disrupt civil-rights, anti-war and other domestic political movements, a claim that sounded like paranoia until burglars stole the paperwork and Congress confirmed the rest.
Read the case file →The Gulf of Tonkin incident that launched the Vietnam War was misrepresented
The naval battle that supposedly launched America into Vietnam turned out to be half real. The first attack happened. The second (the one Congress voted on) almost certainly did not, and the National Security Agency's own declassified history says the signals intelligence used to sell it was misread and then misrepresented.
Read the case file →The US government secretly sold arms to Iran and funneled the money to Nicaraguan rebels
Not a rumor but a proven, prosecuted scandal: senior Reagan administration officials secretly sold arms to Iran, then under a US embargo, and diverted the proceeds to arm Nicaraguan rebels Congress had explicitly forbidden the government to fund. Exposed in late 1986, it produced a presidential commission, a joint congressional inquiry, and criminal convictions of the operation's key figures.
Read the case file →The Pentagon Papers proved the government systematically lied to the public about Vietnam
A classified Defense Department history of the Vietnam War, secretly commissioned by Robert McNamara and leaked by Daniel Ellsberg in 1971, showed on the government's own paper trail that Truman through Johnson had misled Congress and the public about the war's scope and its odds of success. The Supreme Court refused to block publication, and in 2011 the study was declassified in full.
Read the case file →The CIA secretly built a ship to raise a sunken Soviet submarine from the Pacific floor
Not a rumor but a declassified CIA operation: in the early 1970s, the agency secretly built a purpose-designed ship, the Hughes Glomar Explorer, to lift a sunken Soviet ballistic-missile submarine from nearly three miles down in the Pacific, all under the cover story that reclusive billionaire Howard Hughes was mining seabed minerals. Leaked to the press in 1975 and partially declassified by the CIA in 2010, it also produced the legal doctrine now known as the 'Glomar response.'
Read the case file →The U.S. Army secretly planned to hide hundreds of nuclear missiles in tunnels under the Greenland ice
Camp Century was sold to the world in 1960 as a marvel of peacetime science: an under-ice 'city' beneath the Greenland ice sheet, powered by the first mobile nuclear reactor, where U.S. Army engineers studied Arctic construction and glaciologists drilled the first ice core to bedrock. What the public (and even the Danish government that hosted it) was not told is that the base doubled as a feasibility test for Project Iceworm, a top-secret plan to bury up to 600 nuclear missiles in a shifting maze of ice tunnels aimed at the Soviet Union. The scheme was abandoned when the ice itself proved too unstable, and it stayed secret until Danish investigators forced the documents into the open in the 1990s.
Read the case file →The U.S. government spent two decades studying psychic spies
For more than twenty years, the CIA, the Defense Intelligence Agency, and the U.S. Army really did fund an effort to gather intelligence by clairvoyance, a program eventually code-named Star Gate. That the program existed is beyond dispute; it was declassified in 1995 and its files fill the CIA's reading room. Whether "remote viewing" ever actually worked is a separate question, and the government's own final review answered it in the negative.
Read the case file →In 1949 the U.S. government secretly released a radioactive cloud over its own citizens and hid it for decades: the Hanford 'Green Run'
For nearly forty years, an official secret sat in classified files: one December night in 1949, the U.S. government intentionally released a radioactive cloud over its own farmland and told no one. The Hanford Site, the plutonium factory that fueled the Nagasaki bomb, ran what insiders called the Green Run. Operators dissolved 'green' fuel, irradiated uranium cooled for only about sixteen days instead of the usual months, and let the resulting iodine-131 and xenon escape up the stack, apparently to generate a signature that would help U.S. aircraft detect the Soviet Union's new nuclear program. Weather scattered the plume farther than planned, across a region of dairy farms, and no evacuation or warning was issued. The release only came to light in 1986, through declassified documents pried loose by local journalists and activists. This case file lays out what the record firmly establishes, and where the science of downwind harm remains honestly unresolved.
Read the case file →The US military secretly exposed thousands of its own service members to real chemical and biological warfare agents in Cold War tests, then concealed the program for decades
Between 1962 and 1973 the Department of Defense conducted Project 112, a classified chemical and biological warfare test program run out of the Deseret Test Center in Utah. Its sea-based arm, Project SHAD (Shipboard Hazard and Defense), used Navy ships and Army tugboats to gauge how vulnerable US forces were to chemical and biological attack. Roughly 5,900 service members took part. Many tests used harmless simulants and tracer chemicals, but a number involved real agents, including the biological agents that cause Q fever and tularemia, and trace amounts of nerve agents such as sarin and VX. The Pentagon denied the program's existence for decades until a journalist's investigation aired on CBS in 2000, after which the Department of Defense released detailed fact sheets, testified before Congress, and the VA began contacting participants. This case file separates the documented record (a real, now-acknowledged program of chem-bio tests involving service members who were often not told what they were exposed to) from the questions that are still genuinely open (above all, whether the exposures caused lasting harm). On the existence and concealment of the tests, the verdict is substantiated.
Read the case file →Project 1794, the US Air Force's secret flying-saucer program, is the real explanation behind Cold War flying-saucer UFO reports
In the early Cold War the US Air Force quietly funded a Canadian firm, Avro Aircraft Limited of Malton, Ontario, to design a flying saucer. Under the code name Project 1794, engineers led by John Frost sketched a disc-shaped, vertical-takeoff craft meant to reach between Mach 3 and Mach 4, climb above 100,000 feet, and intercept Soviet bombers. A low-speed proof-of-concept vehicle, the VZ-9 Avrocar, was actually built and flown. When the National Archives declassified the program's records in 2012, the documents made headlines and revived an old idea: that secret craft like these, not aliens, were what people saw when they reported flying saucers. This case file separates the documented record (a real, failed saucer-aircraft program, now declassified) from the rated claim (that the program explains the era's UFO reports). The program's existence is not in question; the UFO-explanation claim is unproven, and its strongest form is undercut by how poorly the aircraft actually flew.

The paper trail behind one of ufology's most durable legends: a roll of anonymous film, a purported 1947 Truman order, and the forensic history that led the FBI to stamp the whole file 'BOGUS.'
