Jacobo Arbenz was elected President of Guatemala in 1950 to continue a process of socio-economic reforms that the CIA disdainfully refers to in its memoranda as "an intensely nationalistic program of progress colored by the touchy, anti-foreign inferiority complex of the 'Banana Republic.'" The first CIA effort to overthrow the Guatemalan president - a CIA collaboration with Nicaraguan dictator Anastacio Somoza to support a disgruntled general named Carlos Castillo Armas and codenamed Operation PBFORTUNE - was authorized by President Truman in 1952. As early as February of that year, CIA Headquarters began generating memos with subject titles such as "Guatemalan Communist Personel to be disposed of during Military Operations," outlining categories of persons to be neutralized "through Executive Action" - murder - or through imprisonment and exile. The "A" list of those to be assassinated contained 58 names - all of which the CIA has excised from the declassified documents.
PBSUCCESS, authorized by President Eisenhower in August 1953, carried a $2.7 million budget for "pychological warfare and political action" and "subversion," among the other components of a small paramilitary war. But, according to the CIA's own internal study of the agency's so-called "K program," up until the day Arbenz resigned on June 27, 1954, "the option of assassination was still being considered." While the power of the CIA's psychological-war, codenamed "Operation Sherwood," against Arbenz rendered that option unnecessary, the last stage of PBSUCCESS called for "roll-up of Communists and collaborators." In June 1954, the CIA's operation succeeded in ousting the democratic government and replacing it with a military junta headed by Colonel Carlos Castillo Armas. Although Arbenz and his top aides were able to flee the country, after the CIA installed Castillo Armas in power, hundreds of Guatemalans were rounded up and killed. Between 1954 and 1990, human rights groups estimate, the repressive operatives of sucessive military regimes murdered more than 100,000 civilians.
