Meanwhile, back in the real world

President Obama has mail:

The Iran nuclear deal is not done. Negotiations continue. The target deadline is June 30.  We know much about the emerging agreement. Most of us would have preferred a stronger agreement.

The agreement will not prevent Iran from having a nuclear weapons capability. It will not require the dismantling of Iran’s nuclear enrichment infrastructure. It will however reduce that infrastructure for the next 10 to 15 years. And it will impose a transparency, inspection, and consequences regime with the goal of deterring and dissuading Iran from actually building a nuclear weapon.

The agreement does not purport to be a comprehensive strategy towards Iran. It does not address Iran’s support for terrorist organizations (like Hezbollah and Hamas), its interventions in Iraq, Syria, Lebanon, and Yemen (its “regional hegemony”), its ballistic missile arsenal, or its oppression of its own people. The U.S. administration has prioritized negotiations to deal with the nuclear threat, and hopes that an agreement will positively influence Iranian policy in these other areas.

Even granting this policy approach, we fear that the current negotiations, unless concluded along the lines outlined in this paper and buttressed by a resolute regional strategy, may fall short of meeting the administration’s own standard of a “good” agreement.

So argue the signatories of an open letter, including a variety of officials who were once part of the Obama administration. It's worth reading in full.
