Juanita Castro, younger sister of Fidel and Raul, has revealed that she aided the CIA in working against her brothers in Cuba in the 1960s. Though she initially supported Fidel’s revolution in 1959, "I began to become disenchanted when I saw so much injustice," she said, explaining that her brother had betrayed his democratic principles by turning to Communism and using such violent tactics against opposition. Castro’s memoir, written in Spanish, is about to hit shelves, and she recently broke her silence to Univision, saying that the CIA approached her after she began sheltering enemies of her brother’s regime. “I was rather shocked, but anyway I said yes,” she said. “In this way began a long relationship with the arch-enemy of Fidel Castro, the Central Intelligence Agency.” Castro has been living in exile in Miami since 1964, the last time she spoke to either of her brothers, and ran a community pharmacy there until retiring in 2006.
