Iranian Ex-President Mohammad Khatami in the U.S.!

David Ellwood, dean of Harvard University's John F. Kennedy School of Government defended the decision to invite former Iranian President Mohammad Khatami to speak on the eve of the anniversary of the Sept. 11 terror attacks:

Do we listen to those that we disagree with, and vigorously challenge them, or do we close our ears completely?

He also emphasized that Khatami would not be allowed to visit unless he was willing to take unscripted questions.
