Quote: Point is, would you have ever believed that your country had anything to do with Pinochet coming to power if the documents had never been declassified? I don't think so.
Well, we have to agree to disagree, then.
Quote: If sending a country into a dictatorship isn't enough for you to admit that your country fucked up, what is?
This assumes your country wasn't heading into dictatorship anyway.
As a historical fact, every single communist government on earth has been a dictatorship. If, as you admit, the alternative to Pinochet was a communist government, then the alternative to our "sending [you] into a dictatorship" was you sending yourself into a dictatorship.
I'm simply noting that reality.
You might argue that the U.S. had no "right" to decide which form of dictatorship you got and that you should have been able to choose which form of dictatorship you had. And on that you may have a valid point.
However, even on that point, you need to accept that you still would have been under a dictatorship anyway.
