CIA
The CIA is the Central Intelligence Agency, which is one of the main intelligence agencies that operate in USA. They are involved with international spy networks. They are similar to the FBI, except that the FBI are primarily involved in national (US) interests. In practice, however, they overlap significantly. The CIA have on a number of occasions assassinated or attempted to assassinate foreign targets, including an attempted assassination of Cuban leader Fidel Castro. They supposedly no longer do this. Other things the CIA has done are rigging the Italian elections in the late-1940s to prevent the Communist Party from winning, , helping reactionary dictator Augusto Pinochet start a coup d'etat against the elected democratic socialist Salvador Allende, and backing a monarchist coup in the Republic of Iran, resulting in the creation of a brutal monarchist dictatorship, which was overthrown in the 1970s by a coalition of liberals, democratic socialists, Marxists, and Islamic fundamentalists. The Islamic fundamentalists won the ensuing power-struggle, and the authoritarian Islamic Republic of Iran was formed. This is only a few of the atrocities the CIA has committed.
The CIA generally has a bad reputation now, due to the various assassinations and attempted assassinations, and are widely blamed for any problems caused by any American intelligence agencies, whether they did them or not.
