4. The biggest concession to the Iranians might have already been made. Although it is the West’s position that it has not granted Iran the so-called right to enrich, the text of the interim agreement states that the permanent deal will “involve a mutually defined enrichment program with mutually agreed parameters.” Essentially, Barack Obama’s administration has already conceded, before the main round of negotiations, that Iran is going to end up with the right to enrich. Realists would argue that Iran will end up with that “right” no matter what, but it seems premature to cede the point now.

5. The Geneva agreement only makes the most elliptical references to two indispensable components of any nuclear-weapons program. The entire agreement is focused on the fuel cycle, but there is no promise by Iran in this interim deal to abstain from pursuing work on ballistic missiles or on weaponization. A nuclear weapons program has three main components: the fuel, the warhead and the delivery system. Iran is free, in the coming six-month period of the interim deal, to do whatever it pleases on missiles and warhead development.
