I think today marks the anniversary of a coup led by Augusto Pinochet to overthrow the democratically elected Chilean government led by Salvador Allende, who was the first Marxist to be elected president in a Latin American democracy. The CIA investigated itself using declassified documents and determined no wrongdoing. Just that it "appeared to condone" the coup, but found "no evidence" of any participation, which means the United States definitely participated to some extent in the rise to power of a ruthless autocrat who disappeared or executed thousands of people and interred and tortured tens of thousands more over nearly two decades.
Or something like that.
