The Iran deal and its consequences

Progress has been made on shrinking the size of Iran’s enriched stockpile, confining the enrichment of uranium to one facility, and limiting aspects of the enrichment process. Still, the ultimate significance of the framework will depend on its verifiability and enforceability.

Negotiating the final agreement will be extremely challenging. For one thing, no official text has yet been published. The so-called framework represents a unilateral American interpretation. Some of its clauses have been dismissed by the principal Iranian negotiator as “spin.” A joint EU-Iran statement differs in important respects, especially with regard to the lifting of sanctions and permitted research and development.

Comparable ambiguities apply to the one-year window for a presumed Iranian breakout. Emerging at a relatively late stage in the negotiation, this concept replaced the previous baseline—that Iran might be permitted a technical capacity compatible with a plausible civilian nuclear program. The new approach complicates verification and makes it more political because of the vagueness of the criteria.
