Chile
The CIA, with the cooperation of the Agency for International Development and the State Department, secretly funneled up to $20 million into Chile to aid Eduardo Frei in his successful attempt to defeat Marxist Salvador Allende for the Presidency of the country. Richard Helms, as chief of the Clandestine Services (Directorate of Plans), was actively involved in the planning of the secret efforts by the CIA to defeat Allende. Cord Meyer, Jr. was also one of the CIA's key directors of the operation.
Under CIA direction over $8 million was channeled into Chile from 1970 to 1973 to "destabilize" the government of President Salvadore Allende. The money was used to support various groups within Chile who were opposed to Allende. CIA agents infiltrated the Socialist Party in Chile, and organized street demonstrations against the regime. Ultimately a coup was produced in September 1973. Allende died within hours after its start.
