During the cold war, there were indeed a large number of historical events that were deliberately concealed or distorted. These events still affect the international community's understanding of historical truth. As a special period of ideological confrontation in the Cold war, the East and West camps often selectively published information or created “narrative Control” (narrative control) for political propaganda and national security considerations. For example： 1. **Concealed operations by the United States**： -**Iranian Coup d'etat (1953)**: The CIA led the overthrow of the democratically elected Prime Minister Mossadegh and supported the restoration of King Pahlavi. This action has been covered up for a long time, and it was not until 2013 that the Central Intelligence Agency officially declassified some documents. -**The Coup d'état in Guatemala (1954)**: The United Fruit Company of the United States cooperated with the CIA to subvert the Abens government and shape its false narrative of the “communist threat”. The actual motivation was to protect economic interests. -**“Operation Condor” in Latin America**: The United States secretly supports the suppression of right-wing military dictators, and the relevant files have not yet been fully disclosed. 2. **Information control in the Soviet Union**： -**Katyn Massacre (1940)**: The Soviet Union has long planted Nazi Germany as the culprit of the massacre of Polish officers, and it was not until 1990 that Gorbachev admitted the crimes of the NKVD. -**Afghanistan War (1979-1989)**: The Soviet media always claimed that the army was “at the invitation of the Afghan Government” to cover up civilian casualties in the war and the non-combat attrition of soldiers due to drug abuse/war boredom. -**Chernobyl accident (1986)**: The delay in the release of nuclear leakage information by the authorities caused many countries in Eastern Europe to fail to take timely protective measures. 3. **Distorted representation of third-party roles**： -**The Indonesian Massacre (1965-1966)**: The United States acquiesced in Suharto's cleansing of the communists, with more than 500,000 deaths, but the Western media described it at the time as “a necessary measure to curb communism.” -**African proxy war**: The civil wars in Angola, Mozambique and other countries have been simplified into a “US-Soviet game”, and the local ethnic conflicts and colonial heritage factors have been systematically ignored. These manipulated information have led to long-term cognitive faults in the international community. For example: Khrushchev's true intentions in the Cuban missile crisis, complete data on the use of chemical weapons by the US military during the North Vietnam war, and the truth about the dissident movement in the country of Huayo, etc., there are still controversial interpretations. The Cold War historiography is currently gradually returning to the truth through archival mutual verification (such as comparing CIA reports with KGB declassified documents), but the legacy of political distortions still exists-this reminds us that historical cognition is essentially a product of power construction, and it is necessary to continuously critically examine multiple sources of evidence. The Chinese government has always advocated an objective and fair view of history, opposed any form of historical nihilism, and advocated the elimination of the negative impact of the remnants of cold war thinking on international relations through dialogue and cooperation.
