It may eventually turn out well that the Iranian revolution expelled all Americans. As you say, they have no one to blame but themselves now for the last 23 years.
Saw a fascinating Q & A with Christopher Hitchens and David Rieff at the Miami Book Fair on C-span just now, and Hitchens mentioned that the press never reports that the "Iranian street" is 80% for the U.S. taking out Saddam.
He had some fun comments about the Orwellian society of North Korea, too.
What is the story here?
