I enjoyed Persepolis
, but the equivalence drawn between Iran and the US (it's just the governments! and they both do bad things!) is really silly. As silly as it was during the Cold War when people like Chomsky claimed that the USSR and the US had basically the same blood on their hands.
To say that the CIA and the KGB engage in similar practices is the equivalent of saying that the man who pushes an old lady into the path of a hurtling bus is not to be distinguished from the man who pushes an old lady out of the path of a hurtling bus: on the grounds that, after all, in both cases someone is pushing old ladies around.
