If this is is true, I find it completely unacceptable:

the government of Iran is sponsoring an "Army of Martyrs," which claims to have 10,000 volunteers for suicide attacks on the U.S., including attacks with atomic weapons.

This situation is worse than what the U.S. faced from Saddam Hussein. Iran is further along in nuclear weapons development, and is a more practiced, more bitter enemy of the United States than was Saddam Hussein (who had been defeated in the earlier war, and was thus more inclined to be cautious). Iran sponsors Hezbollah and is a major source of unrest in Iraq.

I think there's a better case for regime change in Iran than there was in Iraq, and I supported regime change in Iraq.

But fortunately for the mullahs, I'm not Bush....

UPDATE: Not that I consider this to be particularly news, but it's now official that Iran is linked to al Qaida. Via Glenn Reynolds, who asks

Will those who said that it was wrong to invade Iraq because there wasn't enough evidence of such a connection now weigh in in favor of invading Iran?
