No. They have to go. And die. Horribly. Let the people revolt, and let them rip the ayatollahs to shreds. Kill Ahmadenijad and all the "12th mahdi" bullshitters, too. Replace them with Western agnostic leaders who are young and tired of Islam and all the misery it brings. .
You are correct. It is up to the people of Iran to rid themselves of the Moolahs and Assahollahs in whatever way they see fit. It is not our job.
