Former military officers from Argentina and Uruguay went on trial in 2013 in Buenos Aires for their human rights abuses in Operation Condor. The cross-border conspiracy of dictatorships in the 1970s and 1980s to "eradicate 'subversion,' a word which increasingly translated into non-violent dissent from the left and center left." These prosecutions were enabled by massive releases of formerly classified documents to the national Security Archive which were then used as evidence against the accused. "The documents are very useful in establishing a comprehensive analytical framework of what Operation Condor was," said Pablo Enrique Ouvina, the lead prosecutor in the case. Of the 171 Condor victims cited in the indictments, approximately forty-two survived and one hundred twenty others were killed and/or disappeared. "Condor was a latter day rendition, torture and assassination program," noted Carlos Osorio, who directs the Archive's Southern Cone Documentation project. "Holding these officials accountable for the multinational crimes of Condor," he said, "cannot help but set a precedent for more recent abuses of a similar nature."
