Haass was frank about the double standard: Iran can't have nukes, but we can live with North Korea's.

The administration would seem more comfortable with a significant North Korean nuclear capability than it would with an Iran that had no capability.

Haass said one reason for the difference is, North Korea has a powerful protector in China, and Iran doesn't:

The problem [for Iran] is Iran does not have the equivalent of a China in its corner in the same way that North Korea does.
