I really cant see them getting many genuine responses to this, although it is quite a good idea. If I thought i'd be paid attention to, I would ask a few questions...but they will obviously only choose to respond to the questions that they can look good by answering.
What i'd most like to ask right now, is why we didnt just nuke iran a month ago when they kidnapped our navy crew. I'm sure the prisoners' release had nothing to do with their announcement a few days later that they were officially nuclear, and unwilling to discuss it while we wanted to stop them.
