The day that Chile¡¯s Augusto Pinochet turned his sights on Washington DC

Orlando Letelier, a Chilean politician who served under Salvador Allende, was assassinated in Washington DC on September 21, 1976, exactly 40 years ago today.

A car bomb went off in the heart of the US capital¡¯s diplomatic neighborhood, taking the lives of the former minister and of his young American aide, Ronni Moffit.

Letelier¡¯s closest circle immediately pointed the finger of blame at Chile¡¯s dictator, Augusto Pinochet, who had deposed the Allende government in a 1973 military coup.

But it would be years before US authorities recognized the authorship of the first terrorist attack sponsored by a foreign government in Washington DC.

Letelier, an exile in the US ever since Pinochet stripped him of Chilean nationality, was in a hurry that morning. Tireless in his efforts to restore democracy in his country, he needed to get to the Institute for Policy Studies (IPS) quickly. The center served as a forum for Letelier¡¯s public denunciation of the Pinochet dictatorship, and he wanted to proofread an article meant for publication in The New York Times, refuting allegations that he was a traitor to his country.

Letelier was known to be a bad driver, so when his assistant Juan Gabriel Vald¨¦s got a call about a road incident, he immediately thought that his boss had crashed the car. The truth ¨C that a commando had been sent in from Chile to plant a bomb under Letelier¡¯s car, and that it had gone off in the middle of Washington DC ¨C was simply inconceivable.

Even Letelier himself, who had been getting more and more death threats in recent times, did not believe that Pinochet would dare attack him in the city that was also home to one of the dictator¡¯s greatest allies, US State Secretary Henry Kissinger.

In time, the US government began considering the assassination of Letelier and Moffit ¡°evidence of the criminal nature of the Chilean regime and of similar regimes in the region,¡± notes Juan Gabriel Vald¨¦s, who went on to become the Chilean ambassador in Washington.

An FBI investigation also ¡°opened up a space for human rights investigations in Argentina and other countries,¡± he adds.

The Jimmy Carter administration kept its distance with Chile and other Latin American dictatorships, but a complete break with Pinochet would not occur for another decade.

On that fateful September 21, a 17-year-old Francisco Pancho Letelier was at school when he was informed that something bad had happened to his dad. The FBI was waiting back at his Bethesda house, where he lived with his mother Isabel and three siblings ¨C including current Chilean senator Juan Pablo Letelier.

¡°All of us, one by one, told them that clearly the perpetrator was Augusto Pinochet,¡± recalls Francisco, now an artist who lives in California.

The first evidence that Pinochet ordered the attack, and that the US knew it, did not see the public light until a year ago. In October 2015, US State Secretary John Kerry handed Chilean President Michelle Bachelet a series of declassified files on the matter.

One of these documents was a secret memorandum written in 1987 by the secretary of state at the time, George Shultz, and meant for Ronald Reagan. The note asserted that the CIA felt there was ¡°convincing proof¡± that Pinochet had personally ordered his intelligence chief [Manuel Contreras] to prepare the assassination.¡±

That CIA report has not been released yet. It is believed to be part of a trove that is yet to see the light. Peter Kornbluh, a journalist who has been fighting for nearly four decades for the release of secret US documents on Chile, calls this report ¡°the Holy Grail in the history of this first act of international terrorism in the US capital.¡±

Getting it declassified is important ¡°not just for the families of the victims, but in order to understand how a foreign government was able to commit a terrorist act in the capital and not pay for it.¡±

The assassination ¡°is part of the history of terrorism that we need to understand to be better prepared to stop other attacks in the future,¡± says Kornbluh.

Forty years later, the memories of that crime remain alive.
