Establishing a tough-minded policy now is the right way to convince Iran there will be immediate penalties should it not implement the deal ...

I don't think it's impossible, but it would depend on a strong and assertive and self-confident American President at the time.

I would suggest that all of us--and I certainly include myself in this--need to go beyond the conventional wisdoms as we think about Iran.

On balance, however, I believe the nuclear deal will deliver more advantages than disadvantages to the U.S.
