If we want a lasting nuclear deal with Iran, it can't be completely one-sided. Paradoxically, we don't want to strong-arm Iran into accepting a deal they hate, but which they are taking because we've left them no choice. A completely one-sided deal might be easier to sell here at home, but that sort of deal is also less likely to endure. In order to last, there has to be something in it for them, both in terms of tangible benefits but also in terms of acknowledging Iranian interests and national pride. Otherwise, the deal won't stick and we'll be back to the current situation of threat-mongering, suspicion, and strategic distraction. That might be an outcome that a few neo-cons want, but hardly anyone else.
