NSC decisions on covert psychological warfare launched CIA secret operations

By Desmond Okafor · August 18, 2026

The shift from gathering intelligence to conducting covert operations stayed buried in numerical files while the agency's psychological warfare began to reshape foreign capitals.

The people of Asia and Latin America spent the latter half of the twentieth century as the laboratory for a new kind of American power. They were the subjects of experiments in instability, the targets of invisible campaigns, and the casualties of a doctrine that viewed sovereignty as a variable to be manipulated.

This trajectory began not with a single order, but with a series of bureaucratic skirmishes in the immediate aftermath of the Second World War. The catalyst is found in the US National Archives, within a series known as the Foreign Relations Numerical Files. The file's catalogue entry records the messy transition from the wartime intelligence apparatus to the permanent, globalized shadow state we now know as the Central Intelligence Agency.

A deadlock in Washington

Before the CIA existed, there was a vacuum. The catalogue entry for the Numerical Files describes the "dissolution of the Office of Strategic Services (OSS)" and a subsequent scramble to decide who would inherit its functions. This was not a smooth handover; it was a struggle for control. The records document "conflicting concepts and plans" between the Bureau of the Budget, the Department of State, the FBI, and the armed services.

For a time, the government was paralyzed by a "deadlock" between the State Department and the military. The State Department attempted to build its own intelligence organization between 1945 and 1947, but the military eventually seized the lead. This tension reveals a fundamental divide in how Washington viewed the postwar world: as a place for diplomacy and statecraft, or as a theater for permanent strategic dominance. The impasse only broke with a letter from the President on January 22, 1946, which established the National Intelligence Authority and the Central Intelligence Group.

The 1947 National Security Act

Under the leadership of figures like Rear Admiral Sidney W. Souers, Lieutenant General Hoyt S. Vandenberg, and Rear Admiral Roscoe H. Hillenkoetter, the intelligence community moved toward legalization and permanence. The catalogue entry highlights the development of the intelligence provisions of the 1947 National Security Act, the legislative bedrock that codified the agency's existence.

However, the most consequential shift recorded in the archival description is not the creation of the agency itself, but the evolution of its mission. The records document the history of National Security Council (NSC) decisions regarding "covert psychological warfare." This is the moment the agency pivoted. The catalogue makes a sharp distinction between "secret intelligence"—the act of collecting information—and "secret operations," the act of intervening in the world.

By authorizing covert psychological warfare, the NSC gave the agency a mandate to do more than watch; it gave them a mandate to act. This distinction is where the human cost began to mount. "Secret intelligence" might mean reading a foreign leader's mail; "secret operations" mean ensuring that leader is removed from power, or that his people are convinced to turn against him through manufactured crises and propaganda. The Numerical Files capture the birth of this capability, transforming the US intelligence establishment from a mirror reflecting the world into a hammer used to shape it.

Asia, Latin America, and the USSR

There is a profound silence in these files that speaks as loudly as the text. The catalogue entry explicitly states that while the series addresses geographical areas including Asia, Latin America, and the USSR, it "does not include documentation of the planning and implementation of specific intelligence operations."

It also notes that the impact of intelligence appraisals upon particular foreign affairs policymaking or negotiations is missing. The record provides the framework—the letters, the memoranda, the general orders, and the directives—but it strips away the specific targets. We are given the blueprint for the machine and the names of the men who built it, but the records of who was crushed by that machine are stored elsewhere.

Related files in the National Archives, such as the European Political Reports from the OSS or the records of the London Office, offer glimpses into the agency's early overseas activities. Similarly, other archives hold fragments of this history, including UK National Archives files on the CIA's presence in Basutoland and Sarawak, and State Department telegrams regarding Western Europe and the South Atlantic. But the Numerical Files remain a study in institutional intent.

They show us that the capacity for "secret operations" was not an accidental byproduct of the Cold War, but a deliberate design choice. The agency was built to be a tool of psychological warfare, an instrument capable of operating outside the bounds of public accountability and diplomatic norms. The record confirms the existence of intelligence reports and analyses dealing with Asia, Latin America, and the USSR, but the catalogue notes that these specific files are not included in this series.
