i think the "letter" was brushed off and dismissed by the bush admin as some kooky manifesto on how the west is evil and iran has no interest in trying to work things out. if you read it for yourself now you have the ability to make up your own mind based on the content and issues discussed. not only that, but by initiating dialogue and putting forth opinions and suggestions now there's somewhat of a bar to measure iran's actions going forward and respond in jest.
