Condor's key members were the governments in Argentina, Chile, Uruguay, Paraguay, Bolivia and Brazil. The United States government provided technical support and supplied military aid to the participants until at least 1978, and again after Republican Ronald Reagan became President in 1981.[2] Such support was frequently routed through the Central Intelligence Agency. Ecuador and Peru later joined the operation in more peripheral roles.[11] These efforts, such as Operation Charly, supported the local juntas in their anti-communist repression.[12]
