>Apart from the six dictatorships involved (Argentina, Brazil, Chile, Bolivia, Paraguay, Uruguay), the U.S. also played an important role, giving its blessing to this operation.

There is some indication that the U.S. (at least the CIA) may have had more involvement than simply 'giving its blessing'.
