We're talking about stopping the world's next Hitler.
For the record, Pinochet was a military dictator resposible for the deaths of thousands of people.... INCLUDING a few Americans who had the misfortune to be in his country during one of his "purges".
It's interesting that you would use a scumbag like Pinochet as an example. Blindness like yours led to the Nazi occupation of most of Europe during WWII. You really need to open your eyes and take a good look at history.
