The main point here seems to be that Mahmoud Ahmadinejad says many things about Israel, and that the sum total of these things is incoherent contradiction. As such, it doesn’t make a ton of sense to credit what he says to one audience (the Iranian people) more than what he says to another (the international community), given that he may have incentive to deceive both. Of course, Ahmadinejad’s statements about Israel certainly call for some scrutiny, but I doubt that Kirchick credits the Iranian president’s statements about the peaceful nature of Iran’s nuclear program. Moreover, the “You’ve criticized Dick Cheney 103 times, but haven’t mentioned Attila the Hun even once; is Cheney really worse than the Scourge of God?” construction is just about the most useless talking point that Kirchick could have invoked.
The other point seems to be that Yglesias needs to regrow the beard.
