The deal is done. Iran has sort-of promised it won’t build nuclear weapons, but even the promise has serious caveats: Iran can continue to build weapons platforms to deliver the non-existent weapons; it can cooperate with friendly countries to acquire enhancements to weapons delivery technology; and it can prevent entry to requested facilities by international inspectors for 24 days per request; it need not account for prior military activity. And Iran will be vastly richer.
Based on the world’s experience with the efficacy of multinational inspection regimes and with Iran specifically, it would be wise to assume that the Islamic Republic will move (continue?) covertly to build nuclear warheads, perhaps just leaving out the nuclear fuel. Iran will likely begin testing rockets so that they will be able to release a future nuclear weapon securely at the right moment to get the right blast effect.
