In late May 1976, the secret police chieftains of six Southern Cone military regimes gathered at a clandestine summit in Santiago, Chile, to create a “new unit, which was given the code name ‘Teseo’”—a reference to Theseus, the mythical Greek King of the Athenians and heroic slayer of the Minotaur, among other enemies. The mission of “Teseo” was to “conduct physical attacks against subversive targets” abroad, particularly militant Latin American leftists in Europe, according to formerly secret CIA intelligence reports turned over today to Argentina by the U.S. government, and posted for the first time by the nongovernmental National Security Archive.

The "Teseo" program represented a new initiative under "Operation Condor"—the clandestine collaboration of Chile, Argentina, Uruguay, Paraguay, Bolivia, and Brazil to strike at their opposition in the Southern Cone and beyond.  At the time, the CIA also managed to obtain the “text of the agreement by Condor countries regulating their operations against subversive targets”—a comprehensive planning paper on financing, staffing, logistics, training, and selection of targets that reveals both the banal and dramatic details of organizing and implementing Condor’s “Teseo” death squad operations. The “Teseo” operations base would be located “at Condor 1 (Argentina).”  Each member country was expected to donate $10,000 to offset operational costs; and dues of $200 would be paid “prior to the 30^th of each month” for maintenance expenses of the operations center. Expenses for agents on assassination missions abroad were estimated at $3,500 per person for ten days, “with an additional $1000 first time out for clothing allowance.”

Individuals to be eliminated, the Condor agreement stated, would be proposed by member services with “final selection…by vote and on the basis of a simple majority.” As a chilling section titled “Execution of the Target” explained: “This is the responsibility of the operational team which will (A) intercept the target, (B) Carry out the Operation, and (C) Escape. With the exception of the team leaders,” the planning paper stated, “the members of the intelligence and operational teams should not know each other for security and functional reasons.”
