Oh no he didn't!!!

Christopher Hitchens in Slate:

This does not necessarily mean that his letter is not a guide to the mentality of the masters who bade him write it. It opens with a few boilerplate paragraphs about American evil-doings (in which the admission that Saddam Hussein's overthrow was welcomed by "the people of the region" is easy to miss). It then turns to a pedantic discussion of the wrongness of the whole existence of the state of Israel, which might have been designed to make professor Juan Cole (who thinks that Khomeinist anti-Zionism is a derivation from Persian poetry) look like a fool and an ignoramus. Ahmadinejad then rams home this point, as it were, by a couple of callous remarks about the Holocaust. And, as if for good measure, he goes on to insinuate that the attack on the World Trade Center was unlikely to have been planned "without coordination with intelligence and security services." If he has evidence about this, he would have done well to present it, but it seems from the context that he believes the "coordination" to have been American.
