On Wednesday's show we ask: Has the Obama administration changed its tone toward Iran and will a more hard-line approach deter Tehran from its nuclear programme?
Joining the show will be Flynt Leverett, the director of the Iran Initiative at the New America Foundation. It is a nonprofit group that identifies new challenges for the US. We will also have Abbas Milani, a co-director of the Iran Democracy Project at the Hoover Institution, a conservative US think tank.
You can join the conversation. Call in with your questions and comments on Wednesday, April 21, at our live time of 1630GMT. Repeats will be aired at 2130GMT, and the next day at 0230GMT and 1130GMT.
