"A CIA plot" goes too far, true. But to believe the CIA isn't involved at all in fomenting revolution in a country whose current government is the result of the CIA having done so in the past, and which the US considers part of the "Axis of Evil," and which is an ally to a country the US is currently waging a war of aggression and plunder against (Venezuela) seems naive.

Yes, it’s possible to believe in an incompetent CIA. Particularly when Iran is directly an adversary to multiple countries in the Middle East and further that it’s been fucking with more recently than the 1970s.
