I think the CIA should disrupt their nuclear potential and if that doesn't work we may need targeted air strikes on their installations. But do you really agree with Sarah that we should declare war on Iran? And do you think we should declare war on ALL nations that have nuclear weapons that don't like us very much? That would include N. Korea, Afghanistan and maybe China. We don't have the right to blow up every country that MAY pose a threat to us. We shouldn't live our lives like Michael Corleone and wipe out all our enemies.  History has shown, that doesn't work either.
