I heard the opposite from many Iranians (including opponents of Ahmadinejad)--the open hostility of Bollinger was seen as so rude and contrary to the norms of hospitality that it overshadowed the content of Ahmadinejad's speech. As a result, he came off (remarkably!) looking like the statesman to domestic mass audiences...
While many in the Iranian foreign policy elite cringe at the President's antics and declarations, don't underestimate the way it plays with both hardliners and his broader voter base, among whom tweaking the US can score domestic points.
