Just curious. As far back as I remember I only hear about them destabilizing countries that aren’t fully in the pocket of American powerplayers. Sometimes they assassinate people, sometimes instigate coups, subvert media… and the #1 way to encounter them seems to be to try and take back control locally of one’s country’s oil and other valuable resources.
So my question is, have they ever done anything good?
Depends on whose side you’re on. If you’re a genocidal maniac like Kissinger, sure they did.
A better question is: has any nation’s intelligence service ever done anything “good” in the history of our species? It’s still no, but with less nationalism.
