Here's the thing about a UN speech and these interviews with US broadcasters and journalists. They are, first and foremost, part of the political show. Ahmadinejad takes the spotlight and, unless someone greases the stage, he will act out his script, take a bow, and present the applause lines to his audience back home.
It is what happens in the wings that matters. And those "noises off", from the political in-fighting in Tehran to the President's attempt at back-channel negotiations with Washington to a systematic approach to detentions and intimidations to contain and fragment any opposition, demand an attention beyond this week in September.
