MK Ultra on its own could count for several.

Was the experiment where they released some "harmless pathogen" (assuming your immune system is all good!) in major cities to see how they spread, resulting in some deaths/complications part of MK Ultra? Can't remember if it was under that project or part of a different one leading up to it.

The Iran/contras were CIA.

Oh also the Iranian revolution, or at least the instability that led to it.

Saddam Hussein and Osama bin Laden both started as CIA assets that got tired of being used.

A lot of attempts on Fidel Castro's life.

That's off the top of my head. There's also a bunch of fuckery in central and south America, though if I had to guess, I would guess that there has been fuckery in every single country on this planet, including countries some would have called allies. Iirc they targeted some Canadian cities for that "release the pathogen" experiment, too.
