United States
The first well-known American rendition case involved the Achille Lauro hijackers in 1985. After they were given a plane and were en route in international air space, they were forced by United States Navy fighter planes to land at the Naval Air Station Sigonella, an Italian military base in Sicily used by the US Navy and NATO. The intent was to bring the hijackers within judicial reach of United States government representatives for transport to and trial in the United States. In September 1987, during the Reagan administration, the United States executed a rendition, code-named "Goldenrod," in a joint FBI-CIA operation. Agents lured Fawaz Yunis, wanted for his role in the hijacking of a Jordanian airliner that had American citizens on board, onto a boat off the coast of Cyprus and taken to international waters, where he was arrested. The Reagan administration did not undertake this kidnapping lightly. Then-FBI Director William H. Webster had opposed an earlier bid to snatch Yunis, arguing that the United States should not adopt the tactics of Israel, which had abducted Adolf Eichmann on a residential street in Buenos Aires, Argentina, in 1960 ... In 1984 and 1986, during a wave of terrorist attacks, Congress passed laws making air piracy and attacks on Americans abroad federal crimes. Ronald Reagan added teeth to these laws by signing a secret covert-action directive in 1986 that authorized the CIA to kidnap, anywhere abroad, foreigners wanted for terrorism. A new word entered the dictionary of U.S. foreign relations: rendition. Vietnam
