Iran should not have been mentioned with Iraq and N. Korea.
The elected part of their government is moderate, the vast majority of the population is moderate (Khatami got 84% of the vote in the last election), they have been holding out olive branches to us ever since Khatami was first elected, they are the most educated country in the region other than Israel, the population is the most liberal in the region and Khatami is already walking a tight rope between what he wants and what the hardline, non-elected clerics want. Iran is potentialy our best and most stable ally in the region, even moreso than Israel, if we can help the moderates oust the conservative clerics.
