Using Nowruz as an Opening

Both US President Obama and, separately, Israeli President Shimon Peres have sent Nowruz greetings to Iran in efforts to thaw the chill: Peres actually speaking in Persian apparently, Obama relying on subtitles. I doubt that it will have much effect (especially Peres), but it's an improvement over confrontrational threats, and at least a reminder that someone in the West noticed it was Nowruz.
