* The agreement on inspections is a form of so-called “managed access”. Inspectors will not be able to conduct “anywhere, any time” visits. Instead, they will have to give grounds for their concerns about prohibited activities and give the Iranians an opportunity to address them before access is made mandatory by the joint commission. All this must take place within two weeks. Refusal by Iran to provide inspectors access that persisted for more than another week would be deemed a violation of the agreement and therefore subject to re-imposition of sanctions.

* Iran will be able to begin deployment of advanced enrichment centrifuges after the first 10 years of an agreement, but for 15 years it will have to keep its stockpile of low-enriched uranium below 300kg. After that, Iran will be able to develop the industrial-scale enrichment it seeks, but while its breakout time to a bomb will notionally diminish from the one year sought by the agreement, its obligations under the AP are perpetual, ensuring that even as its nuclear programme starts to expand again it will do so under conditions of far greater transparency than in the past. As long as future American presidents remain committed to preventing Iran from ever having a bomb and will use force if necessary to prevent it, deterrence should be maintained.
* On the question of the whether or not the arms embargo should be lifted, as the Iranians were demanding, a compromise has been thrashed out that appears to favour the tough line taken by American negotiators. The embargo, as it applies to the sale of offensive weapons to Iran, will remain in force for a further five years, while the ban on any technologies relating to ballistic missiles will stay in place for eight years. That means that the Russians, for example, will be able to go ahead with the sale of the S-300 air defence system, but presumably not of strike aircraft or tanks.
* A mechanism has also been established for dealing with possible Iranian violations of the deal that would allow sanctions to snap back automatically. (65 day process)
