Five days before the assassination in downtown Washington of former Chilean Defence Minister Orlando Letelier, then-Secretary of State Henry Kissinger rescinded instructions to U.S. ambassadors in Latin America’s Southern Cone to warn the region’s military regimes against carrying out “a series of international murders”, according to documents released by the National Security Archive (NSA) here.

Kissinger “has instructed that no further action be taken on this matter”, reads a declassified Sep. 16, 1976 cable sent by Kissinger’s office from Zambia, where he was travelling at the time, to his assistant secretary of state for inter-American affairs, Harry Shlaudeman.

Even Kissinger’s fiercest critics couldn’t accuse him of being a fool. This was no well-meaning attempt to avoid interfering with another nation; he’d have known that likely targets dwelled in countries like his own. That, it seems, is the mark of a true “statesman“: accepting a spree of international murders, and hushing up your own involvement for over a third of a century.
