I agree with Dr. Rice that a nuclear weapon in the hands of Iranian Mullahs will destabilize the Middle East. Since 1979, they have been exporting terror and inciting their co-religionists in Sunni dominated countries to destabilize these countries.

International community will have to support US sanctions against Iran to force it to stop its nuclear enrichment. But it looks that European nations, Russians and Chinese are not willing to back or complement US sanction because of their lucrative business ties to Iran.
