It's easy to find information on bad things the CIA did [1], "minor" things of note including classic hits like "imposing a dictatorship in Iran, leading to an Islamic fundamentalist revolution and thus creating a powerful enemy against the US where there wasn't one before" and "trafficking drugs into the US and greatly amplifying America's drug problems", but looking for times where they actually did good for the country leaves me with little if anything.

The CIA's actions aren't done in national defense. They're a subversive organization. The fact the CIA suddenly shifted from being a shadowy government organization that people pretty much only knew about through action movies to being "open" about their ongoing activities within these past few years raises some red flags. Looking at the CIA's history, it's incredible that anyone would sit there and think they're trustworthy. I encounter people trying to say "well that's in the past" pretty often, which is a silly position to take, because why would they have any reason to stop?
