Here's the deal.

You don't have to make the case for negotiating with Iran, because that's pretty obvious. We don't want another war right now, or ever. Nobody does.

The problem is that when you read the kinds of things Iran's leaders have been saying and doing and their reactions to efforts to stop them from developing nuclear weapons, you have to be concerned, because these people don't care if they destroy their own country and its culture. They think a nuclear holocaust will bring back the 12th Imam.

To overcome that concern, you've got to show that they're all just bluffing. I don't want to wait until they drop a bomb on Tel-Aviv before we decide they're dangerous.
