First off, Jed, I think you misunderstood my question. I know that a strike on nuclear facilities won't result in regime change; I'm worried that it would retard regime change, and I'm wondering if Israel doing the deed would limit anti-American backlash.
And second, I'm a little perplexed by this sentence: "It matters not who rules Iran if they are no threat to us." The current Iranian regime is by its nature a threat to us -- a terror master, to use Michael Ledeen's phrase. I take it you get this, since you call for covert action to destabilize the regime. What I'm concerned about is the tension between, on the one hand, keeping nukes out of the Mullahs' hands, and on the other hand toppling the Mullahs entirely.
