I'm not seeing that so much in the current debate on Iran. Certainly there is still some effort devoted to using carrots and sticks to cause Iran to abandon its nuclear program (however unrealistic that might be). And I don't think the notion that a nuclear armed Iran invariably would undertake regional aggression is nearly as stark (or articulated by senior policymakers) as it was during the Iraq debate. I don't have the Bush administration statements right at my fingertips, but the rhetoric was not if Hussein would renew his regional aggression, but when.
