Iran being much in the news now, it would be well to be informed on the subject of the history of Iran and it's connections to Islam.
Here, a Christian scholar (Frank Turek) interviews an accomplished, contemporary historian (Wm Federer) on the history of Iran.
This is an informative and instructive interview which will prepare one quite well for a constructive dialog on the subject.
