A Chilean officer, accused of murdering prisoners for Pinochet, was allowed to teach for years in the US National Defense University which disregarded the complaints against him.

The US coordinated and encouraged the repression in Chile and other nearby countries in the 1970s, and it continued afterward to shield many of those that carried it out.

I disagree with one person quoted in the article. These murders were not terrorism. Murder of prisoners is a different crime. Stretching the meaning of "terrorism" is an obstacle to clear thinking, so let's not do it.
