because of what the president said. these plus 30 years of a massive wall of mistrust has been built up between the two nations. it affects everything, fredricka. it affects the middle east and america's relations and its ability to operate in that whole region. it is vital, not to mention sorting out the whole nuclear program. so, you know, there has been a willingness expressed by both iranian side now and the u.s. side to have at least some kind of encounter. no one knows whether it will be a handshake or more than that, exchanging words, sitting down. we just don't know. nor do we know it's going to happen. for all i know, iranians haven't decided whether it's going to happen. i'll be interviewing president rowhani later on this afternoon. of course, i'll ask about that, but also all the issues that the president mentioned. >> can't wait to hear that, christiane. the images of it, mahmoud ahmadinejad and also benjamin
