Pinochet came to power following a CIA backed coup d'etat to remove the democratically elected Marxist regime in 1973. Following the coup, the regime took part in Operation Condor; a campaign meant to deter opposition forces and communist influence. It is estimated that some 3,000 people were killed or "disappeared' as a result of Operation Condor in Chili alone.
Amnesty laws in the region made prosecution difficult, even after Chili returned to democracy in 1990. In response to extradition requests by Spain, General Pinochet was arrested in London in 1998. The House of Lords ruled in his arrest that Pinochet lacked immunity under international law; a motion which encouraged Chilean courts to seek justice. In 1999, Chilean courts overcame many of the hurdles by stating that "disappearances' would be considered a crime until death was proven concretely. It was also determined that all applicable Geneva Conventions were in place in Chile due to its technical status of internal conflict following Pinochet's coup. Since then, some 150 people have been convicted of human rights violations and nearly 400 military officials face prosecution.
The willingness and the ability to face past atrocities is a sign post in the maturation of nations. Some argue that these actions only highlight the dark stains in a nation's history, while others make cries for justice. With no contribution to laws regarding human rights and benchmarks of normative behavior, the examination of the past make recovery for future generations possible.
