He was a genuine dissident student, which makes his positioning more dangerous for our naive, easily fooled authorities. He is not a bad guy himself but as you say, he has no choice but to obey Mullah pressures.
Halloween 1977 Carter's DCI Turner fired 820 case officers guttting our humint capability unto this day.Your caveat is that a) the person has a legitimate track record as a dissident; and b) he has been compromised by the peril of his wife in the mullahs' hands as well as relatives of his associates.
You warn he is sent on a mission to discern and misdirect our planning vis-a-vis covert ops, et cetera.
