The U.S. government claim has always been that the CIA was not involved in the murder of Allende and company and the creation of the Pinochet dictatorship. I do not believe them: the extremely... calm reaction of Kissinger and company to the Pinochet government's assassination of Orlando Letelier in Dupont Circle convined me that Pinochet has *something* very damning about U.S. sponsorship of his coup squirreled away in his filing cabinet.
