Iran responds to Obama
Obama's unprecedented greeting to Iran is met with an unprecedented response by Grand Ayatollah Khamenei

Investigative historian and journalist, Gareth Porter, speaks to Sharmini Peries about President Obama's Nowruz greeting to Iran. Noting the significance of this unprecedented move by the US government, and [that] saying that this is the first time the Iranian leader himself has responded directly to the US, Porter said, "Obama was displaying atmospherics here far more than substance," adding that, "there really is nothing in the address that gives you a clue as to what change is going to be made in the US posture when they actually sit down with Iran."
